Liber Umbrarum
This roleplaying supplement explores ghosts who remain on Earth after death, including spirits, poltergeists, phantoms, and other restless dead. It details a dozen new types of ghosts, provides guidance for ghost-centered campaigns, and supports playing a ghost as a character or continuing as one after a character’s death. The book also adds advantages and disadvantages for dealing with ghosts and expands the rules for interactions between the living and the dead.
