Name(s) - Yeine dau she Kinneth tai wer Somem kanna Darre. Yeine, daughter of Kinneth of the Sonnem tribe within the Darre people. Also Yeine Darre, or Yeine Arameri. Just call her Yeine. She's also grown used to being called The Grey Lady, though that was originally Enefa's title.
Sphere - Energy
Age - Nineteen/twenty as a human, then a couple of centuries on top of that. Relatively new as gods go, really.
Physical Description - "I am not very interesting to look at. It might have been different if I had gotten the traits of my two peoples in a better combination. Amn height with Darre curves, perhaps, or thick straight Darre hair colored Amn-pale. I have Amn eyes: faded green in color, more unnerving than pretty. Otherwise I am short and flat and brown as forestwood, and my hair is a curled mess. Because I find it unmanageable otherwise, I wear it short. I am sometimes mistaken for a boy." - The Hundred Thousand Kingdoms.
Other - Yeine moves like someone who's physically fit and on the ball, but she doesn't go out of her way to be graceful. Unless she knows you well and likes you, she'll make a point of keeping a bubble of personal space. Her expression tends toward reserved, trying not to show what she is thinking, but if something gets to her emotionally, she becomes an open book.
Other gods and/or ghosts it applies to might notice that she is *immensely* more powerful at dawn and dusk than at any other time of day.
Patronage - Yeine is likely to patron along thematic ping lines. Said thematic pings include family, ruthlessness, revenge and freedom. If any or all of these are particularly relevant to a ghost, they'd probably make a good match for her. Some characters I can see her patroning in particular include Katniss Everdeen (The Hunger Games,) Ciel Phantomhive (Kuroshitsuji) and Emiya Kiritsugu (Fate/Zero.)
Additionally, the best proteges for her are ones she can respect as capable and driven. She's not hugely cuddly or sensitive, and she won't go out of her way to motivate someone she perceives as inert or passive, but if her protege, who is normally the active sort, hits a rough patch, she will be there for them, absolutely.
She has a soft spot for children - especially mischievous trickster children - as well as chaos gods and their ilk.

She's a god, she can take whatever you throw at her. On the flip side, check out her thematic pings! This is not a woman who will let things slide, though at least her vengeance will be fair, rather than escalating.
And (other) gods help you if you fuck with her proteges or other close CR she forms!
On the death note, Yeine can revive, though there'll probably be hilarious side effects. Something along the lines of a temporary body swap, or memory transfer upon revival.
I really doubt mind control would work on her, at all.
Feel free to fourth-wall. There is a known concept of multiversality within her world. (Well, known to gods, at least...)
