The Shroud is a pervasive mist that twists, corrupts, and alters the physiology and psychology of creatures trapped within it for too long. The creatures that spend their lives within it are something different entirely. The darkness of the Shroud becomes familiar and the suffering of regions affected by the Shroud becomes all they know. Some form of despair or distress becomes all of what these creatures embody.
The Shroudborn are, in part, creatures born of the Shroud, or those twisted and corrupted by it, claiming Humanoids, Monstrocities, Aberrations, Plants, Fey, and others.
