You see dead people, and as a medium have the ability to communicate and interact with them as well.
Mediumship allows you to see, hear and interact with the ghosts and spirits of the departed, whether they wish to be seen or not. Just as you are aware of the spirits present, they too are aware of your presence and know you can see them as well. On a successful Mediumship power check against a difficulty of the Willpower of the target, any ghost, spirit or other incorporeal being in your presence can be touched and affected by you as if they were corporeal beings, and your attacks, powers and other abilities will now work on them as if they were living beings in the real, material world.
You may ask a ghost or spirit in your presence any questions you like, but they are not required to provide truthful answers to you or even answer you at all unless they are under the influence of any mental powers you possess or other means of forcing their will. If you are unable to speak the language that the ghost or spirit spoke in life, make a Mediumship power check against a difficulty of the incorporeal being's Intellect. Success means you are able to communicate verbally and understand each other despite your language differences.
Mediumship requires the ghost or spirit to already be in the immediate vicinity (perhaps anchored to or otherwise haunting the area) for the power to work.
Speak With Dead
As a bonus power or power stunt, you may speak with the ghost or spirit of a departed soul in a manner similar to Séance. Speak With Dead requires that you possess in your presence the corpse or bones of the spirit you wish to summon and communicate with - the spirit will animate the earthly remains and appear to speak through them as it did in life. Make a power check against the Willpower of the spirit you wish to summon and speak with. Success means they heed your call and arrive in your presence, possessing the remains of their corporeal body. They must answer your questions and the questions of all others present truthfully (although some may give cryptic responses) and to the best of their ability. Unlike Séance, however, all present (even if they do not possess the Mediumship power) will see and hear the earthly remains speak with the voice of the departed spirit. All present will be able to understand and communicate with the spirit regardless of language differences.
When randomly rolling characters, Mediumship can be taken in place of ESP.
