"Becoming a spiritualist is not a calling: it’s a phenomenon. When a creature dies, its spirit flees its body and begins the next stage of its existence. Debilitating emotional attachments during life and other psychic corruptions cause some spirits to drift into the Ethereal Plane and descend toward the Negative Energy Plane. Some of these spirits are able to escape the pull of undeath and make their way back to the Material Plane, seeking refuge in a psychically attuned mind. Such a fusing of consciousnesses creates a spiritualist—the master of a single powerful phantom whom the spiritualist can manifest to do her bidding."Pathfinder Spiritualist
