Xur, the strange arms dealer.

Xur the agent of the nine. Xur is a figure shrouded in shadow. It stands hunched over air, in the same position if stabbed through with a spear. Its drapes are of dark cloth, overhanging and concealing all joints and bodily features. It wears a bag strewn at Its back. Within that hoods suffocating darkness lay two iridescent yellow eyes. A writhing mass of matter holds those eyes in their sockets and distinguishes facial features. This untidily dark arching lump is the emissary of the Nine.
