Wraith, Gloom

You feel the air go unnaturally cold. An aura of despair seems to permeate the atmosphere. Those who can see incorporeal undead see a ten-foot-tall figure floating there, covered from head to foot in a tattered black cloak, the face hidden within the hood. Its hands are scabbed and greyish green, like a drowned corpse, and they reach out and try to touch you.
