With most people, repression of emotions can lead to stress or even illness — mental, physical, or both. With some, however, those emotions run deep and hold great power. How does the repressed emotion of a powerful sorcerer manifest itself? What of a young person with the undeveloped potential to be a summoner? Or what if a relatively normal person just dams up a reservoir of repressed emotion, only to have a triggering incident ignite it into life like a tindertwig tossed in a vat of lamp oil? In rare cases these powerful emotions manifest, arising from a person to take on a life of their own. These are the ikiryo, the living spirits. This powerful emotional force is a danger to all it encounters, especially the focus or cause of those emotions, and potentially deadly to those with which it interacts.
