From Introduction:
Rather than presenting a series of events, this Lost Souls scenario describes a number of foes the players can interact with. These foes can be used in the context of the plot presented here, or in an adventure of the narrator’s own design. Besides presenting information on two new supernatural foes (the janus bat and the succubus), this scenario also gives details on a number of human foes, including an evil medium. It also illustrates how a character’s cause of death can become the basis of a complete adventure.
This adventure assumes the central player is a journalist whose cause of death was “Caught in rock star’s slamming door.” His Life & Death history should include “Friend mysteriously murdered.”
