Jill Alar!
Obsidian fur coats her, though as light shifts, you might see it shift in hue to deep purple, or even a deep violet under bright light. Her wings, however, are the easiest place to see the shift, the feathers towards the bottom of them brightening to a slightly more obvious violet.
Of course, being an alar, she has the crest of her family, and it resides on the back of her right hand, as Zalvine called it, an eldritch star, a design so simple yet maddeningly complex.
A star that's not a star, a stellar forge of heat, light and matter...
or a waiting maw, writ large across the very cosmos itself.
Staring at it too long would make one's head progressively hurt as the design seemed to become infinitely more complex.
..Then in a simple blink, it would be normal.
A more personal mark is something of an arcane spiderwebbing pattern over her forearms, each line linking to another. To trace it with the eyes would get the eyes lost, perhaps.
Eyes shine a startlingly deep blue, and sometimes with a hunger that startles even herself. Her inner flesh, and her pawpads, are a mottled mix of obsidian over a background of violet.
Clothes are not something she tends towards, though if she does, they tend to be wraps, or other things modified to better suit her winged nature.
That does, of course, exclude the band of violet about her neck, a well anchored hoop on the front of it. Wuff has a collar, it seems.
