BTW, just to add to Alyssienna's description/looks, she has three long scars across the right side of her face, reaching from the corner of her eye to her jaw.
Reason: Fenrir clawed her face when she refused to go kill some of Harry's allies.
Other Backstory: Parents were former Deatheaters, is Bellatrix Lestrange's neice (unfortunately), her twin, Conner was killed when she refused the Mark, then they threatened her little sister, and, unwilling to let her sister die, accepted the Mark. (She was I guess you could say a child prodigy, not perfect though). Was crucioed repeatedly throughout war for refusing to do what Voldy Wart wanted.
