Stephen Leeds, AKA 'Legion', is a man whose unique mental condition allows him to generate a multitude of personae: hallucinatory entities with a wide variety of personal characteristics and a vast array of highly specialised skills. As the story begins, Leeds and his 'aspects' are drawn into the search for the missing Balubal Razon, inventor of a camera whose astonishing properties could alter our understanding of human history and change the very structure of society.
