Hmm I love the idea and the personality of the character, but there are some problems.
Mainly, only two wolves in my entire story have markings; Kiari and Syri. They are "special" in a way, which is why they have those. No others in the story can, I'm afraid.
Second is that I already have a beta, but I do have an idea where she'd fit in. Possibly a friend of Syri's, or maybe an Elite.
Or unless you'd like her to be more of a bad character (not evil, just on the 'bad' side), there's not much I can do unless she's just a background character, I'm afraid.
