The person who has just crashed into this universe after an instantaneous, eternal fall with a soft crack of displaced air definitely isn't exactly human either, judging by the tail.  And the ears.

"...welllll.  Fuck.  On the plus side, I'm not dead.  On the minus side, I think home might be doomed and I can't really do much about that from here."

She draws herself up into a ready stance, not looking for a fight but nonetheless prepared for one, tail lashing back and forth, a knife that wasn't in evidence a moment ago in her hand as ink shifts beneath her skin, dispelling an orb of light she doesn't need - the slight pressure-itchiness of it almost a comfort - and observes where she landed.  Warm, sea breeze, bright sunshine...

"...I swear, if this is - home -" she barely chokes out the thought, because she means the place she grew up, this time, a place she's long been exiled from due to the plots of gods and monsters and misses dearly, "- again, but - somewhere, somewhen, somehow else...I will pitch such a fit at the universe.  Or praise it, depending on if there's not a repeat sabotage.  But - it doesn't seem right.  There's no coconuts.  And - that's not a presentation of tiefling-bloodedness I've ever seen or heard of before."

"Ahoy!  Where the fuck have I washed up?"

Said not-a-familiar-kind-of-tiefling looks up sharply at the other girl's arrival. She's afraid and startled, but mostly confused. Not more confused than she is afraid, necessarily, but confused enough that for a moment she freezes instead of trying to leave.

"Uh, what?"

She shakes her head, aware that that probably sounded really stupid.

"This island doesn't have a name, I don't think… were you trying to get to the mainland, somehow?"

She doesn't seem surprised enough by the fact that she didn't see or hear the stranger arrive. Disturbed, yes, but… she's been losing time a lot, lately.

"Wasn't really expecting to end up anywhere in particular; when a goddess decides you can't even die in her universe lest what you've done - been manipulated to do - to, undermine other gods or something, leak, you thank your lucky stars you end up anywhere at all.  ...What were you expecting?"

Her tail lashes back and forth stressily, but she's sheathed her knife for now.

This doesn't really un-confuse her!

"Uh, I wasn't really expecting anything. I came out here because there wasn't anyone else to… put at risk."

Her eyes follow the tailswishes. She… doesn't look like a husk, even though she's got nonhuman features. But that doesn't really tell Su-Yeong what she is.

"At risk of...what?"

Her tail continues lashing, and her knife jumps to her hand, drawing a frustrated hiss before she sheathes it again.  "Fucking overeager bloodthirsty -- bleed on your knife once and it never -- ugh.  No, I'm not going to start anything, and I'll help with whatever you're worried about, if I can."  And Su-Yeong might need that reassurance, because underneath a deep blue, and deeply unsuited-for-this-weather, overcoat, which Su-Yeong might be able to see is embellished on the inside with scrap cloth and embroidered ?artwork?, is what is unmistakeably armor.  Not very heavy or all-covering armor, per se, she's no knight, but this woman has clearly experienced people trying to stab her and decided to make that process difficult for anyone attempting it.

She opens her mouth, then closes it. She - wilts, a bit, at Hali's eagerness to defend her.

"At risk of me. You're… really not from around here, huh?"

"I am not!  And - you're a people.  I help people when I can help people!  So - what's happening, that you're worried that you'll hurt someone?"

The question makes her laugh, hard enough that -

She changes, shrinking down to a more human size and amount-of-covered-in-fur. She eeps when she realizes that she's now naked, but she's got enough head hair that she can kind of… make that be less of a problem?

"Um. Sorry about laughing, it's just surprising that you seem to honestly not know. I'm a husk. And that means I'm dangerous, just inherently. I'm not in control of my magic, so if I get mad, there's nothing stopping me from - hurling fireballs, or whatever."

There is a moment of realization-of-what's-happening, followed immediately by what could absolutely be specifically panicked gay not-looking.  "...well if it's control you need, I - actually think I could work something out for that, given time, depending on how the - husk-ness - works?  I'm very good at magic that affects other magic; when you have to counter magic things the hard way you darn well learn all the tips, tricks, weak spots...but also, what's really stopping anyone from doing that?  I literally can't do the wizard thing the way wizards do it and I'm right here with instincts to fireball stuff!"

She takes a moment to process what the other girl said, then - looks up hopefully.

"Okay, so… I don't really know how it all works, I'm not a doctor or anything, but… what happened to me is-"

(She stops herself, touching a hand to her heart and shutting her eyes while she calms her own breathing.)

"Something happened to me, something really bad and humiliating. I can't really go into detail because thinking about it too hard makes me mad, and when I get too mad, I - change. The opposite of how I changed just now, in case that wasn't obvious. And - it isn't all the time, but sometimes I also lose track of time - like, I'll wake up in the morning and go to get some water, and then it'll just be late afternoon and I've just eaten some sort of forest creature, and I don't remember any of it. That sort of thing. And I haven't burned down this place yet, but - it could happen. When I started out, I looked pretty much human, just with the weird eyes, and then a couple days later I looked like this, and after about a week I started being - uh, the bigger me - sometimes. Probably in a few more days I'll be big all the time, and then - I don't know. You're supposed to lose your mind, but most husks don't make it to that point."

(Another deep breath.)

"But - you said you have magic that can directly affect other magic?"

"Yes.  I - I can't promise I'll succeed.  I don't know what this is or how it works or why it's this and not some other thing - but, I'll try.  I - can't not.  Because - fuck, if I was in your shoes...Okay.  Okay, I need to - look at you."

She's still keeping her head averted, keeping only the corner of her eye on Su-Jeong.

"Like, doctor-like.  If I'm going to ever get a good idea of what's happening.

"So...I should have a blanket somewhere, if that would help.  Won't get in the way any, I'm looking at magic."

She does, indeed, have a blanket; she pulled it out of a bag that absolutely shouldn't have fit any such thing inside.  Would Su-Jeong like the blanket?

She nods.

"Thank you. And - for what it's worth, I don't know that anyone really knows why magic is the way it is."

She would like the blanket! She wraps it around her shoulders, not bothering to push her hair out of the way.

Then Hali can take a look at her soul, pulling out a rune-etched jeweler's loupe with which to get a close look once she's taken in an overview with her normal vision.

The first thing that she'll see is that Su-Yeong's soul has two parts. There's the part that looks like a human, of course, but it's connected to a spectral goat. Both human and goat have the glowing red eyes, with a stream of red light connecting each pair.

The goat, agitated, paces around the human, looking like it perceives everything around it as a threat to be challenged. Right now it's peering suspiciously at Hali, but it'll also turn towards the sound of a bird's call or the rustle of leaves.

Looking closer, the magic takes on the appearance of pumping blood, but there's something obviously dysfunctional about it. The channels that it pulses through are - not precisely injured, but they're too small for the volume of angry red magic coursing through it. It's forcing the channels open - has already forced them open wider than they should be - but it's still not enough. She's generating magic too fast.

"Holy what the - okay!  Found the problem!"

And she actually might well have a solution for it, or at least a patch while she can focus on the underlying thing!

"You have way too much magic forcing its way through your soul and your soul goat is spooked as all heck.  I can help with the magic, I cannot immediately solve the trauma response."

She snickers.

"Soul goat?"

That makes it sound like she's got a familiar, somehow. A weird, fucked-up familiar, that doesn't know he's supposed to have his own body instead of - what, appending horns and fur to hers? - but a familiar nonetheless.

She wonders if she'll get to name him.

"What do you plan to do to help with the magic?"

"Bleed it off, not with literal bleeding but with, like, spells that can draw off that reservoir.  Maybe into a different reservoir.  ...And, yeah, there's like, a goat soul.  Attached to your human soul.  By the, like, eyes?  Is that normal here?"

"Bleed it off?"

The goat doesn't like that! It starts pacing faster, rearing up onto its hind legs, glowing brighter, and Su-Yeong starts to glow and grow…

… but the human part of her soul reaches out to the goat and, with great effort, pets it, easing it down, scritching between its horns. She returns to her smaller form. She's quivering a little, but also smiling triumphantly.

"Um, okay, the first thing I want to know is… that won't hurt him, right? Familiars are definitely a normal thing, more people have them than not. I guess I don't know if they're as attached as mine is, but people with magic all have familiars."

"I - I can't be sure, because this isn't something I'm used to working with, but - there's a big problem I see in that you're generating so much magic it's literally bursting the channels between you two, for all that they're not not healing up.  And I think that's not helping either of you!  I will probably need to take a closer, more detailed look for - longer-term things - but for right now, I'm confident that a tap won't hurt either of you."

She nods nervously.

"Okay, I think that - should be okay."

(She closes her eyes again, focusing on what it might be like if this - stranger - succeeds. She could have a real familiar, she could go home, she could eventually get a better job than the - old one. That last one wouldn't be easy, since she doesn't know anyone who might take her in as an apprentice, particularly since she's already an adult, but… she's seen, so many times, the difference between how people with magic and people without are treated. She holds onto that hope until her heart starts to hurt.)

"I'm - ready, I guess? What do you need to do?"

"I need to - well, write some things down, first, because my magic is built off of runes rather than soul-exertion - and then I can give you the thing, and it will hopefully work as intended.

"...Any aesthetic preferences or recommended methods of venting excess magic?"

She laughs - she'd been assuming that this would happen right away.

"Uh, I dunno what's on offer… I think I definitely want it to put my familiar into his own body, so probably you should go out to the mainland and look at some normal people, so you can know what that's supposed to look like. If you can put it into a clear red gemstone - I'm not picky on the kind, but it should be a close color match to my eyes - that would help me look normal, too. I think a necklace or ring would be best, but there's also hairclips and bracelets… I don't have any piercings, by the way, I know some guys do earrings. I guess you can look at magic jewelry while you're visiting the mainland?"

She gets up and starts to pace.

"Now that I'm thinking of it, I'd really like some regular clothes, too, and some food that I don't have to catch and eat raw, but I don't have any money on me and I don't want you to get in hot water for stealing. I guess I could send you to my house, but, no offense, I don't really know you that well yet, and it'd probably freak out my boyfriend. More than he's probably already freaking out…"

(That makes her feel guilty, but - it'll be okay, she tells herself. The weird magic girl is going to fix this.)

"Anyways, you might want to disguise yourself a little, now that I think of it… I think the ears and moving tattoos are fine, they could be illusions, but you should probably hide the tail, and - can you do illusions? Or control animals, if you got a bird to sit on your shoulder that'd do the trick."
