This is the corpse that Raziel uses to shift from the Spectral Realm that you start off at into the Material, or Physical Realm. The Revenant C model was the basis for this. I figure that Raziel is pulling from a similar crop of long-dead corpses so it makes sense they would wind up looking similar. The original game's models are also similar. The differences from the Rev C here are: the corpse is even more gnarled, a bit moldier, completely without clothing or accessories, and with some hair strands added. The corpse is also skinnier; the jaw less thick. The brows are angled more upward; the mouth has a more tragic feel to the shape. It should feel more pained and anguished than malevolent and sinister.
