Seven Kingdoms: Seowyn's Crossing
Twixt is a shifter boy of about ten. He and his twin sister Tween were found by Ghost in the Faewyld where they were living as street thieves along with an older shifter boy named Fish who looked after them. Twixt is the quiet twin. He follows his sister’s lead and after her he follows Fish’s lead. Even when he knows he’s doing something wrong. Which he tries to apologize for even as he’s doing it. But there’s something special about Twixt. He seems to have some affinity for the spirit realm. Before Ghost came across them, Twixt was seeing “a strange cat” in his dreams, a big one, one that was white with odd markings he’d never seen before. The cat, he said, seemed to be telling him that someone was coming to find them, and that they needed to be found.
Twixt and Tween are too young to remember anything of their tribe, being orphaned with no memories of even their parents. They are now living, along with Fish, with Ghost’s elven mentors/foster-family Arun, Jariel and Vondyr where they are being trained in the same ways she was.
