Orpheus is a tabletop role playing game by White Wolf Publishing, set in a microcosm of the World of Darkness. Unlike the other World of Darkness game lines, Orpheus has a specifically planned metaplot and a set number of books that were published. Although it uses the same system as White Wolf's other games, ghosts and spirits are the exclusive focus of this story. Other supernatural creatures in the World of Darkness are strongly discouraged from entering the events of Orpheus. It is, however, tied with Wraith: The Oblivion, White Wolf's previous game dealing with the afterlife; some of the events in Orpheus are related to Ends of Empire, the final book in the Wraith: The Oblivion line.
