Phantom

Many rogues walk a fine line between life and death, risking their own lives and taking the lives of others. While adventuring on that line, some rogues discover a mystical connection to death itself. These rogues take knowledge from the dead and become immersed in negative energy, eventually becoming like Ghost. Thieves' guilds value them as highly effective information gatherers and Spy.
A Phantom can become a wizard's confidant and righthand. In temples of Astus, the Phantom might work as an agent to track down those who try to cheat death and to recover knowledge that might otherwise be lost to the grave.
