Dread wraith

"'This creature is a sinister, spectral figure robed in darkness. It's nearly as large as an ogre, and it has no visible features or appendages except for the glowing red pinpoints of its eyes.'"

The oldest and most malevolent wraiths lurk in the depths of forgotten temples and other forsaken places. They can sense the approach of living creatures, and hunger for them. Despite its size, the dread wraith possesses unearthly quickness, and makes use of its spring attacks and natural reach to strike with deadly effect and melt back into the shadows—or the walls.
