There is a sudden presence in the air before you, and seeming from between two shadows, the woman on horseback emerges, the tall, heavy, black skinned and flame- maned horse lighting the area, the hounds flanking and covering it, the lady herself- as she looks at all of you, it is terribly obvious that all your estimates are dangerously, pofoundly wrong.
Physically, she's a large, strong woman- at or beyond the upper limits for a normal human being, which she may no longer be- but that's not the important part, that is what shines through it.
The poise, presence, and yet almost translucence, the body merely a vessel, a hammer in the hands of her own will, it is possible to see how she managed to convince thousands of mutually hostile maniacs to unite their differences and follow her- both much worse and far better than they could ever hope to be on their own.
Red- violet eyes, impossibly sharp- the gift that Larric has a small touch of, Rohal in greater measure, she has to the last degree. She looks into you, through you all, reads, grasps everything- surface thoughts the least of it; after a mere moment, she knows you, physical, mental, moral drives and limits, strengths and weaknesses- no wonder she's always a move, a dozen moves, ahead.
It doesn't hurt, but it does chill and dislocate, and arguably violate; but what would that gift do, to someone still in the process of growing into an adult? Most thaumaturges come into their talents- they congeal- some time between late youth and adulthood, about the second half of growing up. A terrifying time to suddenly have the head of everyone around you laid open, to have to deal with, understand all of that, to try to be a self in the middle of it all.
What emerged from the process is this almost incandescently driven woman, for whom boundaries scarcely exist; evil- by some definitions, yes, including some that she probably shares. Unable to turn back, definitely, and probably also by temperament unwilling- what does she see when she looks at herself?
It may be as well that you cannot return the favour. She's probably- hopefully- much better grounded in herself, but the faintly fire- illuminated trail of spectres that hover behind her will never leave her now, and only grow longer with time and chance.
