Meet Sister Bernice - newest initiate into the order of Saint Celestion. Such is her devotion to the faith that she and her young companion, Sister Ruth, have undertaken a pilgrimage to the planet Agora, birthplace of the blessed Saint himself. The pilgrims aren't alone, however. Also on the planet is a team of archaeologists searching for the lost tomb of Celestion - a subject in which Sister Bernice seems curiously interested... In her quest to unearth an ancient relic that will point the way to Legion, Bernice will face some fearsome challenges: the dreaded Blood Beast of Thaloon, the randiest Bishop in the galaxy, and an ancient cult with some very bad habits indeed.
