(He is an ambush predator. If he's not moving around a ton, he does just look like a weirdly stunted tree with vines on it. Most Male Goada do. They don't have the weirdly human faces like the Ents from lord of the rings, they're more like mutated, carnivorous trees. Soul eating carnivorous trees. If Sin thought about it, with the exception of his awful night vision, Valspan is an amazing night watchman, because he doesn't need sleep and his vines can drape over most of the deck to give away anyone he can't see. Just a thought.)
