When the body dies, the spark usually leaves the body going to wherever it's strongest part takes it. Often this will be to an appropriate otherworld associated with the beings that was worshipped in life. Sparks of people who were not in any way devout or insightful may wander and eventually fade before finding a home in the otherworlds. Sparks of people who committed acts against some god that they are associated with or that generally trucked with bad beings of the otherworlds may end up in unpleasant otherworlds as a result.
