Seldsin's slender, obsidian-skinned body stands tall for a drow at several inches under six foot.
He sports an athletic and lithe build with little, but pronounced muscle - obviously a person of grace rather than strength.

His pure white hair is left long enough to reach down his back past his shoulders and lacks any attempts to style it besides a few locks bound in intricate silver clasps to form a short, wide ponytail and two tresses draped over the front of each of his shoulders.

Along with the rest of his features typical to drow are his eyes, which possess twin violet irises.
