Alright, I was thinking a very young male drow runaway that finds his way into Nightwood, to be be found out by Brand stealing away food and trinkets from his other adopted young children to survive. Brand has some pity and benefit of the doubt and takes him in, teaching him with the others, but later down the line he finally rubs most the wrong way and runs off to be a bandit or whatnot. I'd love to incorporate some of the PC's already into his story.
