She looks like she has saved up all of her decadent and slothful impulses for a solid decade and is indulging them all at once. She is sprawled on a couch with a book she's only half-reading, and an ice cream sundae, and smiiiiiiling.
So it's okay if I just check you out rather than trying to get Liselen to explain what 'Dark' even means or what causes the Wild Magic to trust people et cetera?
Tialle's Demon is approximately twelve thousand years old. The first thousand or so of those years were spent in Shadow Mountain, home of the Endarkened, where he was frequently tortured, usually in an attempt to punish him for not enjoying other people's suffering enough. He really doesn't enjoy other people's suffering. Eventually he escaped and found a dragon, and it turned out that they were extremely fundamentally similar, so much so that the mental sharing inherent in their Bond never ended and they continue to share a consciousness to this day.
Ever since they Bonded, they have been living together on a remote island being quietly lonely and quietly resigned to the inevitability of one day being found and killed either by enough other Endarkened to overpower them or by non-Endarkened who will expect Tialle's Demon to be as cruel and dangerous and terrifying as the rest of his kind.
They are somewhat suspicious of Kithabel, but they are content to wait and see how trustworthy she turns out to be. And if she really does introduce them to another of the same sort-of-person, and if they really can Bond to that person (the last time they spoke to another sapient creature was long before multiple Dragonbonds were a thing), then they will be very happy about that.
The similarities to Jewel are pervasive and obvious. The way Jewel refused to participate in the Hunger Games and the way Tialle's Demon refused to participate in the torture-centric Endarkened culture share a nearly identical underlying attitude.
Yep, says Kithabel, that sure is three of one person, that's weird. Jewel, you may expect to experience permanent mindsharey-whatnot in this particular case if you do the staring-bonding thing.
Jewel shrugs. Okay.
Yeah, I thought you'd say that. Any last minute objections to me fetching the hermit dragon and beloved thereof?
The hermit dragon's beloved is six and a half feet tall, winged, tailed, bright red, and not wearing pants.
The dragon's beloved is now wearing pants. "Milliways has a rule against nudity," she says.
"Hm? Oh." He looks down and shrugs.
"Wow, okay," he says, laughing. "Omnipotence. Cool."
"...You'll want to set up a thing so you only do stuff when you mean to."
"Wow, why was that not already a thing - yeah, got it."
"Good. It's not a problem for non-omnipotent sorcerers, by and large, because there's nonzero effort in adopting enough of a mental posture for any given effect and by the time they have massive amounts of momentum to throw around they've got decades of practice or more, but for new omnipotences it's a thing."
Shrug. "Okay, so I guess we all traipse back home and I take over the world now? Unless you still wanted to help?"
"I actually recommend hanging out here for a while learning things from Bar, who knows many things and might be able to give you useful otherworldly inspiration. But unless you want me along there's no point to bringing me home with you."
"I'm on board with useful otherworldly inspiration."
Charmed napkins Bar.
"Hi! Got any advice for me?"
"Well, okay, what can you tell me about my world? Is it really just Panem or are there other people out there?"
"Okay. District 13, huh? That'll be fun," he muses.
