“That follow-up was to answer your question and address your comment, not something immediately actionable.”

There is something wrong.  Plausibly she is emotionally exhausted at finding out she is stranded on another planet in an alternate reality …and finding out Gods are able to read her thoughts …and finding out about alarming new forms of magic …and any of the dozen other revelations.  Okay, actually emotional exhaustion seems past plausible and more into nearly certain!  And he doesn’t know if her magic is actually tiring or exhausting!

“I have one more topic we should discuss before tomorrow, but it can wait.  Also, I am unfamiliar with your magic and its endurance or usage limits or concentration requirements.  You’ve made it seem effortless so far, but if you need a break, or even to stop for the day entirely, that seems reasonable, you’ve already performed more magic for much longer than anyone used to this planet’s magic would expect.”

He really hopes he hasn’t let her critically exhaust herself.

Of course she made it seem effortless, she is a consummate professional!

And she is definitely not tired. 'Tired' is when you've had an average of four hours sleep a night for the past ten days, up in the air from sundown to sunup putting out fires on a front that stretches across a continent where air superiority a fond memory, and now the enemy is threatening to break through the lines again because they apparently have infinite reinforcements so your adjutant regretfully shakes you awake to inform you that she has run out of coffee.

But Tanya doesn't owe these people such a high degree of service, and she definitely doesn't want to grow tired enough to be mentally impaired in case she needs to negotiate with Terendelev later tonight. And while it's not exactly the same, she has grown quite tired of talking to Jon.

"I do not absolutely have to stop for the day, but perhaps it would be prudent to conceal this from observers, and I don't know if and when my services might be required next. Let's ask Terendelev" - not for permission to return to base, she doesn't need her permission, "how important she thinks it is for us to stay up."

Terendelev can be seen flying between groups of soldiers, helping to clear larger buildings. 

She uses a message once Tanya gets close enough and makes herself visible.

“Tanya, do you need relief?  I can assign some bodyguards and we can use a room at the cathedral which is protected against scrying and teleports.”

Does Terendelev even have someone who could relieve her and if she does why wasn't that someone up there at the beginning of the fighting? Whatever, it's not Tanya's problem at the moment.

"I would appreciate a rest. And since I had to come down at some point, it seemed prudent to ask if you expect to need my help again later and what the tradeoffs are. I presume further briefing will be done at the secure location, assuming the bodyguards have clearance." 

The next best option is Terendelev herself, flying to each building as they prepare to clear it, and making copious use of her icy breath.

“Follow me to the cathedral.  I’ll choose someone who can be trusted to be discreet and is competent to resist the common spells to obtain information from them.  You can ask them for more local context - I don’t know what Jon knows or would have told you, Outsiders can vary very widely in how much local context they have.”

Hopefully Jon isn’t one of the outsiders who struggle with understanding the basics of human psychology, but Iomedae may have had to make some tradeoffs…

“Actually if you don’t mind Jon could come with me to brief me on what you’re willing to share while you’re being briefed?”

(Terendelev included him in her message.)

“We didn’t actually discuss yet what parts of our discussion Tanya wants to keep confidential between us?  I’ve given a very loose high level discussion of some of the major concerns, but for her end, what she personally wants kept secret I don’t know yet.”

Tanya wasn't aware that confidentiality from Terendelev was on offer! It makes sense, as Jon is representing the higher-ups even if he might not be particularly senior himself, but Tanya doesn't know what she'd trust Iomedae's organization with but not Terendelev. She knows many more terrible things about Iomedae than she does about Terendelev, but those are 1) things divulged freely, 2) things believed locally which may or may not be actually true, 3) lacking the context and explanations that are not known locally, and 4) she hasn't really had a chance to talk to Terendelev and for all she knows she's a terrible person and an incompetent administrator who got her job by taking stupid risks and killing people.

And even if Iomedae keeps her secrets from Terendelev - which she well might, Tanya has no idea how important or powerful Terendelev really is in Iomedae's local organization - Terendelev will very likely take orders from Iomedae, or at least heavily incentivized offers, so does it really matter?

She goes quickly over everything she remembers saying to Jon. Some of her capabilities which she hasn't demonstrated; best to keep those back on general principles. That she's from Earth and the possibilities of different Earths, which she doubts Terendelev can do anything about... Then her reactions to the local torture 'afterlives' and the divine mind-reading...

"I haven't had time to consider the question, and Jon didn't tell me much about you or this city or Iomedae's local followers. For now, please keep information about capabilities I haven't demonstrated and about my origin secret unless immediately relevant to local planning, in which case ask me. I hope I will be able to share it once I better understand the implications" (and in a more secure location with fewer poorly-vetted guards). "My concerns about, uh, things related to the gods don't seem actionable but if you think it useful to share them, please let me know." Complaining about gods is a good way to get on their worshippers' bad side. "To be clear my concerns are more with the information leaking and not with you personally knowing it," she adds to Terendelev. (This isn't strictly true but it's the polite thing to say.) 

...she belatedly realize that this offer might represent Jon or Iomedae's organization themselves not fully trusting Terendelev. Well, Jon can refrain from fully briefing Terendelev but he'll have to coordinate with Tanya to make it work, so it's not her problem for now. Right now she has a promise of payment from Terendelev, while Jon directed her to other local organizations and didn't hint at making any direct deals.

"Understood."

He would have been a little worried she hadn't taken his offer seriously if she expressed no preferences with that.

Golarion's gods might be really concerning in comparison to other planets, they've got a lot of Evil gods!  She’ll try not to dwell on it until Jon has had a chance to let Tanya know what he plans to share.

She leads them to the cathedral and announces herself, then messages a soldier.

"I need a secure room... a confessional will work I suppose if the meeting rooms are in use.  I need Ser Brogan, and two other fighters fit for bodyguarding a caster, paladins if we can spare any."

They are led back into a small room, big enough for just two people with an extendable screen in the middle.  Terendelev folds the screen back.

An elderly man in plate armor arrives a minute or so later.

"You requested me, Lady Terendelev?"

He practically radiates courage and calmness, Tanya's anxieties become substantially easier to manage as he steps into the room.

"This is Tanya von Degurechaff, she is the source of the so called 'miracle of the angel of light' everyone has been discussing.  She arrived in Kenabres, disoriented and missing some memories.  She is from another planet, a very different planet, with very different magic.  Very strong magic, as you may infer from the fact that she sent Deskari himself fleeing and slew most other demons in a single beam of light.  She needs a rest, the exact level of her magic still available and magic spent is a secret.  Her source as the miracle is currently secret.  She also needs local context, I've had a spyglass archon acting as a spotter for her and providing local context, but well local as in the sense of 'this planet', and archons you know..."

She doesn't want to insult Jon and she doesn't know he even made any mistakes...

"Thank you, lady, er, Von Degurechaff."  He says with warm sincerity (despite stumbling over the noble title).

He smiles beatifically "The ways of angels are not the ways of mortal men." He says as if reciting a well known proverb.

He addresses Jon "Has it been long, ah, since you were mortal?  If you ever were?"

He doesn't feel embarrassed, he's hopeful a mortal human can better address the whole 'emotionally exhausted/distressed thing' in a human way?  (Maybe a hug or something, but he has some vague intuition inbetween Tanya's professionalism and human social norms a hug wouldn't quite work?) 

"Some millennia, and I wasn't human or from Golarion, but I have had many summons and some calls to this planet before."

Also, he hadn't realized Deskari himself had shown up prior to his calling!  It is kind of surprising Deskari doesn't have fire immunity, but besides that it makes sense Tanya's physics-based (and thus spell resistance-bypassing) magic could wound him.

"Yes, of course."  Gentle smile.

"I will serve in this role to the best of my ability."

He turns to Tanya.

"Although I am certainly not the most learned in this city, I at least know my letters and try to keep up with news from afar.  Von Degurechaff, I will keep your secrets safe... save for the demons utterly breaking my will first."

He remembers the last part after a momentary pause, he should be clear about when and how his word holds true.

What a dignified-looking person! He practically radiates calm and competence. Tanya feels a little better just looking at him.

Tanya was awarded a knighthood, so she supposes addressing her as 'lady' is appropriate. This might be the first time anyone has done so; her military rank always took precedence and she (luckily) never had to attend any court functions. She doesn't endorse the concept of nobility - people should be equal before the law - but as long as it exists, she would rather go through life as 'Lady' than as 'Lt. Colonel'. After all, it's always easier to give up privileges than to demand them, and it makes you look better too.

She is about to tell him that calling her 'Lady' is unnecessary but stops herself just in time, because she doesn't know the appropriate honorific for any of them! (Except that Terendelev is a Lady too?) She's a bumbling foreigner here and must be careful to avoid offense, now that she's out of actual combat where terseness can be excused. 

...she feels like learning an entire new set of keigo ought to be a very intimidating process but it - surprisingly doesn't feel that way? Ah, well, being regularly shot at really puts social missteps in proportion; Tanya is happy for that silver lining of the cloud of her military career.

"Thank you, sir." That's how Terendelev addressed him, right? "Is it truly feasible to keep the secret that I am behind these attacks? I understand from Jon that you don't have long-range magic detectors, but I have flown close to the ground several times including during the first attack. Optical illusions and decoys aside, anyone in the city who spent the day carefully observing might recognize my face or mana signatures or both. In fact, my decoy illusions looked like me at first, I was seen with Terendelev several times, and when I first arrived in the city I talked to her in public where anyone could have overheard us."

More importantly: Jon is immortal? ...or at least the locals believe so. But really, when you can reincarnate souls, why not make your faithful employees immortal? Think of the incredible quality of personnel with thousands of years of experience behind them! Not having to replace your best and most senior people with green recruits is already a huge bonus to any organization, but think how much better those best people could be if you could recruit from across the ages! 

...admittedly this doesn't seem to be a very good description of, well, Jon? Well, perhaps that is why he remains a relatively junior employee on-call for dangerous deployments after thousands of years. But also, if senior people never retire, junior ones can't be promoted without laterally growing the organization, which in turn requires recruiting even more people into junior positions...

In any case, what an employment benefit to be able to offer people! They probably don't have to pay them much or offer good working conditions; they'll have qualified applicants flooding HR no matter what. Being fired is a literal death sentence, and even if you keep your memories your next reincarnation might be on a 'mortal' reservation planet! Reincarnation must be the tightest-kept secret technology there is; it's no wonder people are willing to call those who monopolize it gods.

He's unsure about how to address her!  Not worried though, never worried.  He suppresses his urge to try to recall foreign styles of titles, it won't help with someone not even from this planet.  She didn't seem bothered by his slip, so he'll focus on her question for the moment.

"For the time being... all sorts of wild rumors are flying around: a foreign type of sorcerer from Tian Xia, a miracle out of heaven, a 'light' dragon with beams of light for breath... I was partial to the theory an emergency scroll of Gate was used, the more learned of us know that even an archmage sorcerer would have have run out spells before now and the aid was too sustained to be a divine smiting out of Heaven."

He thinks for a moment.

"We could try to figure out who was around you in the city and what they know?  In the longer term... demons are pretty poor at distributing intelligence... but even they will eventually start to pick through the rumors."

He puzzles it out.

"Concealing your existence in the long term might not be practical, but maybe we could disguise you as an Angel or Archon?  Maybe with the right magic items it could work...  Lady Terendelev have you ever heard of an item that does Angelic Aspect, at least the lesser version?"

"No but I like the direction you are thinking in.  You can work on that with Tanya after you finish briefing her, comparing what of her magic she is willing to reveal to you with what options of this planet's magic are available.  Given the state of the city, I plan to prioritize making money for the next few years anyway, so you should consider even rare or more expensive items."

"If Deskari himself witnessed and bore an attack from Tanya, he may have more insight into her and her magic, as a Demon Lord he would have a variety of exotic senses.  For example, he can sense through his swarms.  Despite that, I concur some form of deception is worth considering if Tanya is planning on aiding the Worldwound and Mendev further.  For the time being I have her under Nondetection and Undetectable Alignment."

There, that was a clear way to indicate to the Paladin that his detect evil won't work on Tanya so he won't feel deceived if he later learns Tanya is Lawful Evil, without actually revealing the fact that Tanya is Lawful Evil!

He tries to think of any other points he might be missing.

He had really hoped Von Degurechaff would stick around longer!  The Worldwound is the worse problem on the continent!  Well, if an Archon thinks she has better things to do, maybe, but still.  At least they had her for today.

He is also thinking about how the Archon and Terendelev aren't getting her title (titles?) right!  He really doesn't want to offend the foreign (other worldly?) adventurer.  (Is she a youthfully faced halfing, or some other race or somehow genuinely as young as she looks?  He'll also want to figure out a gracious way to ask that doesn't condescend to her at all.)

"I do not know nearly enough about the local situation to make plans yet, or to make any long-term commitments to pretend to be someone else. I am concerned with my short-term security, but I probably can't make useful suggestions about ruses and information management. Speaking of which, is this location as secure and as confidential as we're going to get, or should I postpone some discussions until later? The highest grade of security will be needed when I sleep, but if it is not too expensive then it would be nice to relax at other times too." That she'll be defenseless while she's sleeping is presumably obvious and not a serious information leak. She hopes Terendelev will get the hint and tell her how much she trusts Brogan.

(Since the room is a confessional, it is presumably hard to overhear conversations in it for anyone but the divine management.)

“This room is under a mage’s private sanctum, and the cathderal is under a forbiddance and is our best defended location in the city.  The only thing more secure is a demiplane and I have one but it requires multiple spells to get to and back from and I don’t anticipate having the spells available to spare today.”

She glances to Jon to see if he has anything to add…

He can read subtexts if they are about security precautions!

“Paladins (of which I believe Ser Brogan is one?) have an unusually strong protective effect granted to them by their God.” glancing at Ser Brogan “(I assume Iomedae in your case?)”

“This makes them hard to unwillingly use divination magic on or extract information from.”

“Which brings me to a concern I should mention sooner, rather than later.  Moderately powerful or more paladins have an anti-fear aura that makes nearby allies resistant to fear.  I am unsure if this is wanted in Tanya’s case, I worry it might be an unwanted mental influence?”
