Ghost

From Project: Redcap

Ghosts in Ars Magica can belong to any of the supernatural realms. Some explanations on ghosts, and sample ghosts, are given at Houses of Hermes: True Lineages, pages 126-129, and Realms of Power: Magic, pages 115-118. The Mysteries Revised Edition includes one mystery that allows a magus to becomes immortal by becoming a living ghost.
