Allison is a short, pert, perky, black-haired, human, kinda cute young (human) woman.  She's obviously chatty, seems rather cheerful, and is usually smiling.  Often (or at least some of the time) she displays a sharp wit (that in some cases may bite too deeply).  Despite the youthful exuberance, when necessary she can shift and be less flighty and frivolous.

She wears studded leather armor; like her hair, it is black.  She wears leather gloves cut so the fingers are exposed -- the gloves are black.  Her boots; black.  It seems she likes the color black.  If it weren't for her personality, one might think she is a brooding, moody teenager . . . or in mourning . . . but again, these assumptions are readily contradicted by surface signs of her disposition: upbeat, positive, smiling.

She is armed with a sword and a crossbow.  She also carries a backpack.  (Of course, it's black . . . )
