Sadde's running.
Not for any particular reason, just because it's faster. He's been meaning to go to one of the capitals for a bit and now, he supposes, is as good a time as any.
And eventually he's not running anymore, because he's close enough to civilisation that someone might spot him. Not that he wouldn't be able to notice them by scent before they saw him, but still. And as he makes his way to the Norway capital at this more leisurely pace, he notices the tiny, shiny key. He walks towards it and picks it up and immediately notices just how magic it is. He can tell by the way the key feels like things, and different things depending on where it is.
He verifies that what the key feels like is consistent in absolute location by waving it around a bit and seeing that the same place always feels the same. "Huh," he murmurs to himself.
He straightens up and thinks. The first obvious thing to try is seeing whether it opens any doors—a universal skeleton key sounds like the kind of thing a magical key could be—but the second obvious thing can be tested right there and then. He pushes the key into thin air with some purpose, as if he wanted to unlock an invisible door, and then turns it, et voilà, the faintest of door-shaped outlines appears before him.
He locks the door, and it disappears. Unlocks it again, and there it is. So he pulls it open and sees—
It has some fire pits, actually a fair number of them, and lots of plants of various kinds that look like they would have been ridiculously hard to grow together in that way but they look really picturesque.
In this park are people of odd ethnic mishmashes - blue eyed black people, redheaded ice-pale people with Indian features, Jewish noses on folks who would otherwise look Asian - and they seem to be demons. Everybody's got bat wings; some of them have horns, many have tails, a few have claws and hooves and fangy teeth.
It seems to be a musical gathering of some kind! Everybody's got sheet music and are picking their way through a weird polyphony. There's two demons on flutes, there's an electric cello and an elaborate drum set and an unidentifiable form of horn and one demon on a violin -
Demons begin conversing in various unfamiliar languages and finally they start addressing Sadde in more recognizable terms - "Sprechen Sie Deutsch?" "¿Hablas Español?" "Parlez-vous Francais?"
It's the one who looks like a non-mixed-up white guy and is also the hottest person alive who tries, "D'you speak English?"
He recognises the questions even if he can't properly answer all of them. "Je parle français, oui, but English is my first language, hello there," he says in what he hopes of his most seductive tone of voice, not taking his eyes off the hot one for a second. Not even to blink.
Some of the demons, who apparently don't speak English, disengage from the conversation. There is a brief discussion of who is to take charge of the new guy - "we've got two flutes, Zoray, you take him" "what, no, lookit him eyefucking Cam" "and do you think Cam wants to be eyefucked?" "what's he going to do, put me over my recommended daily allowance?" and then Cam puts his violin down and motions Sadde away from the resumed jam session.
Speaking of eyes, at this point Cam might notice just how golden Sadde's are.
"...that's a very, very unexpected question. I'm pretty sure I'm not dead." He's not eyefucking Cam, but he's definitely still eyeing him. "Did I accidentally end up in the afterlife? Should I be concerned it's called Hell? Is anyone going to try torturing me for eternity?"
"The pits of fire are not and have never been intended to contain people. You already speak some languages and you didn't come with your own set of wings, which, around here, generally means that you are a dead ex-human new demon as opposed to an ex nihilo new demon."
Sadde has, of course, realised by now just why he thinks Cam is the hottest person alive, so he's trying to play it cool and such, because the prospect of scaring this person away is absolutely terrifying don't even think it oh my god, play it cool, be cool.
"Roughly accurate. Now, given that I used a magic portal to end up in what appears to be an afterlife, and furthermore you seemed to think I should know what a daeva is or how to summon one, I'm gonna go out on a limb and assume I'm actually from a completely different world, or universe, or however you wanna call that."
"I'm not completely having you on," he reassures this god amongst (im)mortals. "So, anyway, before I go any further, I think the most immediately relevant fact about my kind of vampire is that we have this magical soulmate thing going on where if I lay eyes on a person I'm mutually romantically compatible with I am instantly and magically in love with them forever. And that happened when I looked at you."
"That makes a lot of sense in hindsight," he comments. Also: he's not being immediately rejected by Cam! Ee. Eeeeee. Eeeeeeeeeeeeeeeeeeeeeee! "By the way, you don't seem surprised by the fact that you'd fall in love with a guy so I presume you're attracted to guys? Typically this magic soulmate thing selects for sexual compatibility but in my case I also have some extra magic that means I can shapeshift and I am often also female ssssooooo I didn't know how that'd interact." Is it obvious there's only one thing he can think about now?
Do not jump his bones do not jump his bones you will break them and also that's not cool consent is a thing you can get him to fall for you the regular way even if that takes very long because you two are in fact compatible and aaaaaaaargh!
"Uh. Sure. So. There's three kinds of daeva, demons and angels and fairies. Demons make things, angels change things, fairies move things. All three can be summoned by humans in the mortal realm by drawing variously elaborate circular designs on the floor and then they can exchange goods and services for the hire of our cool magic powers. If a human summons somebody and then they die they become a daeva, exactly how it's determined which type is unclear but I suspect personality compatibility with the magic type; humans who die without having summoned anyone go to Limbo which is really boring and disappointing but not awful or anything. Daeva are indestructible and immortal and heal very rapidly from small injuries; Limboites actually get that too but no powers and their world doesn't have much in it to start out and unlike angels and demons they can't naturally fix that. We export a lot during the concordances, which are periods of smallish overlap between any pair of non-mortal worlds."
"Can you qualify that? Making things and changing things and moving things? Can daeva summon other daeva? Can anyone summon Limboites? And how indestructible are we talking, here? You felt pretty squeezable," and also like heaven, we should touch again, in fact we should touch a lot for a very long time.
Cam makes an M&M in the palm of his hand, displays it, and eats it. "Making things," he repeats. "Angels can shrink or transmute or grow or attach or detach - trained right they're good healers. Fairies are telekinetic. Daeva can't summon, no summoning Limboites, and very indestructible but only past a certain point, like, if you shot me I'd bleed and fall over but I wouldn't crack my skull."
"Yup! They took over, uh, last year, relatively speaking. The previous shadow government was very terrible, but the new one's great, they're slowly peeling the Masquerade and making sure vampires don't kill humans and figuring out a way to make artificial blood that doesn't taste like death the way non-human blood does and their long-term goals seem to be making everyone who wants to one form or another of immortal."
"Yup! And so can I, in fact, due to my personal type of magic, and I was in fact on my way to one of their capitals to offer my services when I stumbled upon the key," and this time he shows it to Cam. "Decided to test, created magic portal, saw you, fell in love, and here I am."
"Superspeed, superstrength, don't need to breathe, don't need to sleep, don't age, unless someone can disable me and set me on fire I'm pretty indestructible, supersenses, incredibly enhanced cognition, perfect recall, very fine precision over every movement, never needing to actually sit down or rest at all, being preternaturally beautiful."
...he's not just been hurt by a wave of despair and depression. Nope. Not at all. He's completely 100% not crushed.
(It's so good he has this much control over his muscles and body language.)
(...well, he may have gone completely still, there.)
"It, uh, really is symmetrical, for what it's worth. Like, even when one of the people in the relationship isn't a vampire, the magical thing seems to, er, filter pretty well."
"Right. Of course. That's entirely reasonable. I'm not totally in control of my emotions right now, the lots of extra room in my brain and the unfamiliarity of the mate bond are a bit hard to process. What the not-in-love-with-you me would've said, I think, would be that of course we shouldn't go full speed ahead, and you have all the time in the world to think it over, and you're naturally free to say no and decide it's not for you."
"...I would very much prefer to be around you as much as possible. Also—" And his skin becomes slightly less pale, more like when he was human. "Vampires sparkle under sunlight, this was my personal magic at work to make me look less vampirey. I didn't list that 'cause I don't exactly see it as an unqualified superpower."
"Well, that and - we've got an equilibrium here that involves everybody being really indestructible and all contests being evenly matched and no permanent harm being done if someone drops someone else in a black hole, I don't know that the reaction you'd get would be universally friendly."
"I mean, I've never been holed, and it'd take a real antisocial type to hole you here in the center of Hellish civilization where a lot of people are in the middle of doing things and wouldn't like to be interrupted by a black hole. But it's a thing now and then. I just don't recommend letting on that you aren't a demon. My shuttle's over there, let's just go hide you in my house."
"Hell is very tacky. We can all make anything on a whim and getting rid of it is a lot harder and there's no incentive to recycle. One day someone wanted to make an enormous plane of gold. Now a lot of demons hang out on it. There are some planets nearish by but mostly it's the plane of gold."
That is such a great face.
"How does gravity even work, there?"
"So the plane of gold is actually large enough to generate its own gravitational field? That's actually really cool."
(Thank the gods of vampire magic that he can see Cam's shirtless glory without having to actually look at it.)
"Disadvantage number one or two, depending on how you're counting it, of being a vampire is that humans smell, look, and taste appetising enough to turn otherwise upstanding people into serial murderers. The other disadvantage number one or two is that the turning process consists in three days of pure agony that would be enough to kill a human, and that agony doesn't even disappear from your throat and flares whenever you smell human. You eventually get used to it, especially on an animal diet, but the first year's tough."
"...it is very possible to get to much worse states than that. The fact that you're more immortal than I am is a pretty huge advantage, most vampires don't really survive the death of their mates, and the ones who do tend to not be functional members of society. Erm. And in the spirit of full disclosure, if you asked me to go away forever and never see you again I would but I might just bury myself somewhere and stay there, maybe give you the address if you ever changed your mind. That said, you rejecting me now would not be substantially better or worse, I think, than you rejecting me in a week or something. And also given the nature of the beast, if you do start anything you're very unlikely to regret it."
"...that you're likely to be thoughtful, smart, good, probably quite ambitious, probably tolerant of weird things like switching genders, confident, er, I never really stopped to think about what my soulmate would look like given that I'd just instantly know. There are a few more specific things, like I'd expect my soulmate to be the kind of person who'd take kindly to my talking a lot and disclosing a lot of information and who'd want to be informed of the soulmate thing soon probably."
"Yeah, pretty much. I mean, I'm pretty certain I wouldn't mate on a non-vegetarian—that's how we call vampires who subsist on animal blood, vegetarians. And just like I could go away if you asked me to, I," imperceptible vampire pause, "think I'd go away if I knew my mate wasn't vegetarian and didn't want to change. And actually when I turned I had been planning on overthrowing the previous evil shadow government but then stuff happened and someone else did first and now being a serial murderer is a crime."
He's okay with it.
And he finishes wrapping his arms around Cam and there is kissing and Sadde continues being careful not to break Cam until he's modified his muscles enough that he feels he won't actually (fail to) break Cam if he stops holding back.
Yes, lots of those! And since he got what he's interpreting as carte blanche, he soon kicks his shoes and socks off, and stops doing the wandering hands thing to start getting rid of his trousers. He doesn't fumble with them because that'd imply less than perfect control over his movements and awareness of his body and environments, but their current position does make it somewhat awkward so he soon growls in frustration and just rips them off—not by strength alone, since he's pretty much reduced his to human levels, but rather by using his witchcraft to produce tiny barbs on his legs that'd do the job for him. It's reduced to tatters after he's done.
And to allow Cam to answer, the kisses move down his jaw to his neck. Also it's much easier for Sadde to take off his briefs than it was his trousers.
"So," he pulls away to start, looking up at Cam's face, "is this an appropriate time for me to ask you to conjure condoms?"
"Terribly good points! I'm not feeling very female at the moment and even if I did I'd need some several editing to even be capable of conceiving. But that being the case..." He gives his current object of affections a goodbye with his tongue and then makes his way back up so he's nibbling on Cam's neck again.
He really won't suggest anything particularly kinky for at least a week.
"I would prefer you wearing nothing, but shirtless is pretty good. I won't say two weeks of uninterrupted you is enough but it's definitely a good start," she says, grinning and going after him, completely naked herself. "So, this is the part where we actually get to know each other, right?"
"I've told you my name. I'm a vampire, and I'm in your house because I'm magically in love with you and you decided that being a vampire in Hell was probably not going to be good for me, and also you wanted to think about what to do with a vampire who's magically in love with you. What were your conclusions?"
"...Honestly, my conclusions were that I didn't have enough information to decide if you're relationship material but your obvious intense lust was really distracting from figuring that out and I didn't have a principled objection to shuffling the old-fashioned order of operations. I'm not sure I have worn it down to a non-distracting level, though. You may be some kind of lust vampire."
"Hmm, well, I wouldn't be surprised if I was lustier than most other vampires, given that when I was a human I think I had a pretty high sex drive, relatively speaking. But two weeks of uninterrupted lewdness doesn't sound too excessive for when two vampires mate on each other, from what I've gathered."
"Well... I'm not a vampire. I'm a demon. So. I live in this house, occasionally I go to the plane of gold to do random social things like the music assembly you dropped in on, and frequently, I take summons, which have me out of Hell altogether for hours or days. What do you see yourself doing inserted into this lifestyle?"
"Summoners draw circles soliciting a random demon because they don't know one who has the skills or disposition they're looking for, first to grab it gets it and vanishes from Hell and appears in the circle. No passengers. Variety of things. Put out forest fires, build space stations, make houses. I really want to terraform Mars but so far nobody will let me."
"Summonings can have bindings. They're an important safety precaution - you don't want to summon a random demon, find that you got a sociopath, and have them suck the Earth into a black hole - but the gag's there so we don't talk them out of their souls, even though we can't actually collect. Aaaand is that how it works? Open portals? We should probably go do something about that."
"I didn't get much chance to actually test it, I was in the middle of doing that when soulmate magic hit me in the forehead and it kinda slipped my mind, but yes, we should. Why do they think you'd talk them out of their souls? How can you talk someone out of their soul?"
"I'm not sure. The key feels like stuff, depending on where it is, but it's a really vague feeling—I'm not sure if it's vaguer for non-vampires or just the same for everyone—and I haven't tested what this feeling means but my hunch is that it somehow correlates with what world the door will open to. Like I said, I didn't really test it much." She offers it to him.
It's fairly obvious that the key is magic the instant Cam takes it, and even moving it from Sadde's hand to a spot closer to his eyes is enough to trigger the "feeling," as impossible to explain as sight to one born blind. It's golden, small enough to fit in a child's hand, and, other than the ineffable feeling, completely ordinary.
Some points don't feel like anything, but most points do. The feeling is very vague, and while apparently completely random, there are places where it's similar enough to other places that it might actually be the same. And any given location always feels the same no matter how many times he moves the location there or how long he waits to return to it.
Eventually she settles on a design that has a pair of limbs leaving from between her shoulder blades and separating into four "fingers" that end in blunted claws, with a fifth claw protruding from where the fingers join, and a thin membrane between all of them, basically a completely black version of this.
"Alright. I think I could pull off making these on my own but it'd probably take some trial and error to get them fully functional. I'm also already pretty non-vampire due to not wanting to squish you, it won't be too hard..." Pause. "Everything but nerves and blood vessels is human, now."
She's turned her body human enough that she actually starts crying, and she tries contorting her way towards Cam without actually uncurling. She's not very successful, so she just reaches out for him with her arms, trying to pull him into a hug or, or something. "Didn't—didn't—think," she sobs.
She whimpers and moans and sobs a bit. "Pain- I don't—turning, the venom's—!" She scrunches her eyes shut and tries to snuggle up, tries to make herself small, make herself disappear in Cam's arms. "Vampire venom—turning is—three days, pain, burns—" He might get an idea of just how much it hurts from the fact that it's enough to turn someone with a whole vampire's worth of brain into a sobbing incoherent mess.
Sadde helps along with biokinesis, and the wings fall off, and she lets out a breath she'd been holding—being partially human is weird—and slowly calms down, enough to explain: "Turning is a very painful process. It lasts three days, the venom reforms our whole body. I—should've expected this to happen, once the venom got into contact with it." She says it all in a small monotone.
Hug! Cling. "I guess I'm not turning really human? I don't know, I don't actually know what's going on on a biological level, my power's awareness of what's going on is less specific than that. Maybe it's because my blood vessels are already dealing with the venom, maybe I'm just mimicking a human body, I don't know."
"Can you make new ones attached to, I don't know, a circulatory system or something that will keep them alive for long enough for the venom to turn them? They should have my DNA for me to be able to properly attach them to myself but—I should probably just try making my own before anything."
"No idea, just seems to be a hard magical limit, but I'm kind of glad we can't, can you imagine? Right now the equilibrium in Hell is that everyone is indestructible and has fantastic magical powers and can instantly replace anything of theirs you destroy. Imagine if anybody who felt like it could make an army of second-class citizens."
"There are no detectable flaws in the copy when we copy a human brain. We just get a basement dweller. It affects animals too, anything smarter than like a snail will be pretty clearly stupider than it's supposed to be. And fortunately at least in humans there's enough mind/body interaction that we also can't get female basement dwellers to carry to term and get Hell-dwelling humans that way, although we can get, like, cats, so there are cats."
"Not usually. When a person goes to Limbo, they get approximately their favorite thing, and that's sometimes a pet. Those have roughly normal intelligence for the species, it seems to these people like the pet has continuity with the live version if applicable, and they get indestructibility too - stuff in Limbo in general does in a kind of cool way, like, if your Limbo thing is a house you can give away everything in your fridge and find bacon there the next morning, run the water constantly with no real plumbing, etcetera."
"I have my medical and engineering quals up to the highest levels available in organized demonic education, and I play the violin, and I have learned several languages the long way, and I can program, and I keep up with media, mostly human some demon smatterings of angel and fairy and Limboite."
"...that's not really how my brain works. I can't generalise from my own experience to other vampires, but given the number of thoughts I can have going on at the same time, and given that I'm mated to you, I don't know if there'll be a single second for the rest of eternity I won't spend thinking about having sex with you at least a little. That said, it's not nearly as much of an insistent priority as it was when we met."
"We should fix that. We should definitely fix that. I wonder how many tries I'd need to open a door to your world, we could get you to terraform Mars. Or maybe find a way to mine and bring standards of living to 2159's, I'm sure the Empress Regnant wouldn't mind. Also I wonder if I could summon other daeva from here, not being a demon but not being a human either."
"And they have all done so. Although the early twenty-first century probably needs me and is less likely to shoot random people trying to get rid of me than current Mars. Where I'd actually really like to go if we're on general flights of fancy is Limbo. It's flat earth and one thing per person and that's it. And I could see my parents."
She tests that the two spots still feel the same—they do—and presses the key into the one on the right. It goes through the wall as if it weren't there, and the shimmering door appears. She creates a second door on the other spot—it's shaped differently, a bit larger—and then opens both. One of them leads underground, and the other about twelve feet above the surface of a desert. "If it's the same world, it's definitely not the same place in that world."
She closes her eyes. "It does not help to think about you having had sex with anyone else. I know it happened, you're gorgeous and sexy and have this horrible tendency to go around strutting your shirtless glory—please don't ever stop that—but the bond is a. Pretty strong instinct." She opens her eyes again.
She doesn't growl. There's no growling going on. The fact that he's been having sex for one hundred and thirty years is none of her business. "It does mean you'd probably either been spending a lot of time alone or around blind people," she tries and mostly fails to say lightly.
"I hope you're not buying into the stereotype that most demons are rapists. I was a virgin until I was forty-something because that's about how long it took me to figure I didn't necessarily have to be in true love or anything, not because nobody ever looked at me twice."
"I think there aren't any demons where I'm from, and while extrapolating from two examples isn't a super great idea, two universes with humans plus something else, presumably demons are as rare as vampires in the multiversal scheme of things. But I get your point, I suppose, I'm just not sure what you want me to do with it."
"Mm, yeah, there's a reason why I didn't list the ability to form mate bonds amongst my superpowers. All in all, between falling in love with you the regular way and the magical way, I'd probably prefer the former, especially if the end result was still this, but here we are."
"Telling them about it, giving them pamphlets, with some luck get the magic princess to impart instant knowledge on them, if it works out they become vampires too and the couple lives happily ever after. Forcibly turning anyone is a crime, for whatever reason, and for as long as one doesn't actually look at a potential mate, there's no mate bond formed, so if the culprit is found before their mate has finished turning they are removed from the premises with more magic so that the victim doesn't get into a relationship they don't want."
"I'm not the first vegetarian vampire. And, I don't know, when I turned I was very adamant about preferring to die than to become a serial murderer. Also most vampires didn't use to get much warning before being turned, but I got some, the person who turned me explained it all to me while I was still human and was very, erm, decent about not eating people and not letting me eat people while she was taking care of me during my newborn year."
"...mind-affecting gunk isn't very accurate. My brain works differently, there's a lot more room, but everything occupies a lot more space. I could spend hours staring at a mote of dust in the air, analysing the way light hit it or following it as drafts moved it about, scrutinising its shape, comparing it to the rest of the world, composing still images of it in my memory. A happy surprise is a wave of unending joy, a mild disappointment is crushing despair, hunger is an all-consuming need, the smell of blood is utmost temptation, I can go on being poetic for a bit but I think you get it. And then there are a few extra instincts installed, for how to move my body, how to react to other vampires, how to stalk and hunt."
"I know. The whatever it is that makes people go slurp is that humans smell and taste just that good. The mate thing is... harder to explain, I suppose, it is an extra magical thing that's tacked on, but I think it may be perfectly explainable by love times brain architecture... times a hundred maybe, I think even if a vampire falls in love with a non-mate the feeling's less intense."
"It's not the growling itself that disconcerted me - it didn't bother me when it was a 'ooh, we are about to have sex' growl - it's the underlying unsettling fact that you are, through no fault of your own, internally very possessive about a period of time during which - how old are you?"
"Debatably single genderfluid vampire seeks... gallivanting and sex no strings attached? Unholy demonic matrimony? Lounging on the plane of gold watching astroworks go up confessing secrets? Action, adventure, rescuing each other from miscellaneous otherworldly fates? What do you want?"
"I would rather neither of us need rescuing, but I want... If I were to just take it for granted that you'd come with me, I want to terraform your Mars and bring the standards of living where I'm from to those of 2159 daeva-having Earth and open a portal to Limbo so Limboites could have an actually nice afterlife and go world-hopping looking for more things to fix. I want to be useful and help other people and learn a lot of new stuff, figure out physics, or meta-physics if it turns out they change from one universe to another, and the physics of each of the universes I visit. Which I guess aren't all very romantic or couple-y activities but I guess you being there doing those things with me would be enough, as far as relationship goals go."
And so:
success!
"Well, there's some nuance to the thing I called 'pessimism' or 'creativity about horror.' I try to think about the ways things could go wrong and to come up with ways the universe will screw me over, and that's at least in large part meant to balance out my innate recklessness."
"They told me about Limbo. I tried to summon Limboites. Doesn't seem to be doable, at least not with anything based on the same principle. It is entirely possible that they just didn't know about the ex-summoners, there's billions of daeva and had never been many summoners before I came along and blew the secret wide open."
"No. I didn't have anything productive to suggest be done about it - couldn't summon anyone to give them stuff, the daeva realms already give them stuff - and I didn't want to distract from the revolution in every form of material scarcity that I was trying to kick off. And it hasn't come up in the time since because I don't even know why - the demons can't talk, the fairies and angels usually can - but I've seen no sign of humans knowing about it. If I'd lived longer I might have orchestrated a reveal about that too, because it's possible to correspond with Limbo via daeva, but it's so laborious and time consuming that it didn't seem urgent - there wasn't a Limbo concordance of any kind during the time between Revelation and my death."
"Apparently the door just didn't let air through, so no sucking occurred. I didn't try sticking the radio there though, since no other doors I opened went to space. Which is actually also pretty interesting, there's much more space than not-space, finding not-space should be basically impossible."
The space probe will see: space. Nothing particularly interesting about it, other than it being space—no nearby planets or stars or even debris.
"Yeah, it made me wonder if the universe of origin, or the place in the universe of origin, could have something to do with it. I wasn't exactly in a public place back in my world, I was in fact in the middle of some woods, but I was closer to, uh, civilisation, so to speak, than we currently are."
"Let's see, what other tests are there. Trying to summon you from another universe but we should wait until we're sure you're not receiving any other summons while technically-summoned, there's still in theory a chance these portals close themselves after a while but we have no reason to believe that anymore... Is there a good reason for me to try summoning fairies and angels here?"
"Right, I was thinking about that but haven't really come up with anything plausible. I do wanna explore your circles a bit more, though, like that 'used up' part, and see if I can't find any principle we'd be able to generalise to summon Limboites that no one did for daeva..."
"Hello, summoner," he says, looking at Sadde and barely glancing at Cam, "what can I do for you?"
Cam answers anyway: "He's just doing a summoning for kicks. Want some cookies for your time?"
"Uh," says the fairy, "sure."
Cam makes him some cookies.
"My planet currently looks a lot like what yours would in 2012 if... well, if you did not exist. Plus my brand of magic, if it has any kinds of strange radio signals I wouldn't know but I wouldn't count on it, plus the shadow government slowly taking over. And now that I think about it, you could access the Golden Empire's website, too, so that's one, I guess."
"I'm not sure? I mean, I did open a couple of portals literally underground, so all that'd accomplish would be that whoever opened the one back home would find solid matter on the other side, or something. If they're a vampire, though, destroying pretty much anything is cake if they're curious about whatever's there. Can you make a basement-dweller you with your kind of indestructibility?"
"Well, this one's definitely not shaped like the one I opened here," he comments, and then opens it. Tundra, with a strange mammal-looking thing in the distance.
"Now I'm wondering what happens if I try to open a door that intersects with this one..." He closes the door but doesn't lock it, and then tries to use a spot in the middle of it as keyhole. "Doesn't feel like anything," he comments, and tries to unlock. No banana. "Interesting."
"Oh well. Um. Okay, so, basically no experimental results regarding the portal from my world, some experimental results about intersecting portals." He locks the latest one. "That still leaves the possibility that someone else could come from my world and suffer unpleasantness."
"Yeah." Pause. "I wonder what happens if your summoner dies while you're in different universes, if voluntary dismissal doesn't work across. I definitely don't want to test that one, unless we find someone with a terminal disease who'd like to try and a daeva who wants to risk never being summonable again."
"I want to see whether summoning works when neither of us is in Hell. The experimental setup I have in mind is I open a door here, someone else holds it open, then I go through the door and open a second door somewhere else, go through that door and open a third door somewhere else. Then one of us goes through the third door, the other of us locks it and gives the key to the person holding the second door, that person locks it. That way we're both in two different universes and completely disconnected from Hell. Then I try to summon you. The thing where dismissal doesn't work apparently doesn't care whether I'm in Hell or not, since I was when it didn't."
"Yeah. This is a really annoying key. But I mean, there may be some correlation between things that isn't... immediately obvious. If we're going to basically go the brute force way anyway, I might as well arbitrarily choose to try to find places that feel the same way this world felt when I opened a door to it."
