Somewhere, in a dimension far away, a chain reaction begins.
Until--finally--it crashes.
It doesn't, exactly, have a spatial location within the universes it passes through. It isn't that kind of phenomenon. But it links to specific concepts, and so while there isn't exactly any coordinate that it definitely occupies, coordinates closely linked with its central concept are places where it sort-of is. Generally it isn't in any one dimension long enough for this to matter, but when it finally stops--
Something happens to Areelu's laboratory. She--can't actually identify what; it's not like anything she's ever experienced before. Not that she's never been disoriented before, but this is--still different--
She takes notes, on what she can observe of it; she has the Concentration for that. Once it's over, she checks everything she can think of, to see if she can divine anything about what that was, or in case it let in any hostiles, or had any effects of its own--
The pieces of Seshka's soul are missing.
Areelu does not handle this well.
She looks for them, of course. In the entirety of her demiplane, first. There are test subjects who suffer, because she is unhappy.
She tries scrying them. It isn't the first thing she tries, by some margin, but it's something she would give more than one attempt, before giving into despair.
And there--
She smacks into the pavement.
It wouldn't quite be accurate to say she falls onto the street; she didn't have a prior location above the street to fall onto it from. But she is, very suddenly, there, horizontally oriented on the ground, a ground which is made up of stones that are not sufficiently even and well-fitted that none of them poke her in any locations.
Oof.
"It's this way!"
The square where the festival is occurring is lovely, draped in all kinds of banners, with musicians playing jaunty dancing music. There's free drinks, and dummies and targets to show off punching skills and marksmanship, and all kinds of other festival panoply.
--Oh, fuck, that's bad. Why are demons invading a random Mendevian city. How are demons invading a random Mendevian city. Okay, first priority has got to be finding safe places to put civilians; even if her purification powers work on demons as well as could possibly be hoped, there are too many of them--
THIS IS REALLY REALLY BAD.
Would...whatever process made her...really have dumped her in a situation she couldn't survive? What a waste.
...But babies are stillborn all the time. There's no reason, really, to expect the process that produced her to work better than that. It feels like it should, but it always feels like bad things shouldn't happen to you, personally.
There's so much that she wants to do, and she can't do it if she dies to a freak demon attack, but--
Think.
Okay, first of all, there's a child with her. Second--it would be pretty bad if they made an undead out of that dragon. Would they? They're demons, not necromancers, they could totally just decide to eat it--but they could also, like, not.
"Stay with me," she tells the elven child who found her. "I'll try to protect you."
Okay, great, mission accomplished, how is kiddo holding up--wah!
Okay, so, like.
She has wings. Probably she could have recovered gracefully from a chasm opening up under her feet.
You know, if her first instinct had been to do that, instead of to lunge for the child close enough to her to also have been in the path of the fissure, and wrap her up tight to protect her as much as possible from the fall.
...She feels like there was supposed to be something happening soon that was not super compatible with a giant horrible rift to the Abyss! But she can't even remember what it is so she definitely can't argue that a giant horrible rift to the Abyss shouldn't have happened, except, you know, for all the normal ways a giant horrible rift to the abyss shouldn't happen.
"I...guess that explains Deskari."
Well, she doesn't actually have all that much experience wielding tentacles that aren't attached to her body, and like, the tentacle-related experience she does have is a bit awash in other identities, so the sudden lunge does get her out of the grapple, but the resulting stab isn't theoretically lethal this time, and she's capable of getting her hands on the girl's rapier and demiplaning it.
"Thanks." It's starting to get a little awkward not to know the kid's name but asking would open her up to questions about her name and that is not a kettle of fish she wants to fry right now.
It really isn't obvious to her what's wrong with Violence And Shitty Lying Lady--on a root level, not an expressions of bad behavior level--and whatever it is, she's pretty confident it's something wrong with her, not some kind of abyssal contamination or anything, but...she really really does not have any better ideas than trying to magic her better.
She kneels down beside the woman's sleeping body and attempts to examine her more closely with her People Being Not Okay sense.
...Better than she ought to be, for magic reasons? Like, if there's some specific trauma that's turning you evil, or you'd benefit from a smack upside the head with a big Empathy Stick, she can work with that? Like, she does have a direct sensory apparatus specifically into things being wrong with people!
DAMMIT SHE DOES NOT HAVE TIME FOR THIS SHIT.
She teleports out of the woman's attempt to strangle her with her bare hands.
Her Golarion instincts say to kill the bitch and ask Nirvana to send a good lawyer. Instincts formed in more civilized areas say MURDER BAD. Less instinctive responses from civilized places say killing in self-defense is fine but, like, she's not that worried about preventing this woman from killing her now that her sword is gone, and--
"Wonderful."
Okay, well, there are a bunch of armed groups of people with only normal amounts or less of thing-wrong-with-them fighting the demons. She picks the largest and most successful-looking group and bops over.
”Hi, I have an unlimited,” technically inaccurate but it doesn’t run on spell slots and she isn’t, like, immediately about to run out of mana or anything, “short-range teleportation ability, if I can get you guys somewhere halfway defensible can you protect wounded.”
“That is—sort of complicated—uh, ‘at will’ was actually a huge oversimplification. I, uh, don’t have spell slots? Instead I have a thing called ‘mana’ that I regenerate over time, at a rate that depends on stuff, and any given spell costs a certain amount of mana, and teleporting more people at a time is faster but costs more total mana than teleporting the same number of people in smaller groups.”
That is very weird. This person does not detect as Evil, but there are ways to fake that, and “demons playing silly buggers” happens a lot more often than people with really weird magic.
But then, “demons playing silly buggers” just happens a lot anyway, and it’s not like weird magic is unheard of. Not using spell slots at all is weirder than the fact that the evil Count Arendae channels positive, but not by that wide a margin.
And being incredibly suspicious of helpful people is Hulrun’s job.
”Okay. This place was a good choice in the short term, and useful for collecting the survivors clustered around this area, but in the long term I’d rather have a base less centrally located to the spot where Deskari showed up.” And Terendelev was horribly murdered.
“Someplace that we can get out of on our own if we have to—demons can teleport too.” Not literally all of them but enough that it’s not worth explicitly qualifying. “If the Gray Garrison hasn’t fallen, that would probably be the best choice.” Especially since it looked like that was the direction Deskari launched the Wardstone in. It’s probably fallen, though.
Most of the rank-and-file present would have no idea what the straight-line distance is between the temple of Iomedae and the Gray Garrison, but fortunately Irabeth has occasioned to work with people who could, or had familiars who could, fly, such that it happened to come up. Direction is easier.
