Storyline
An anonymous, rich, crippled American gets books from the Tibetan monastery at Qanguptoy, from which he learns the art of soul projection. Longing for an adventure, and restricted by his earthly body, he looks at the sky one night and sees a green star (referred later as The Green Star) and projects his soul to a cloud-covered planet revolving around it. The texts of the five volumes of the series are ostensibly transcripts of first-person narratives by the anonymous author recounting his adventures: the first after he took the (preserved) body of Chong The Mighty, and returned to earth after Chong was killed by a brigand; the rest, in his second incarnation as Karn The Hunter (where the author had taken over Karn's just-dead body). Through a bequest, these come into the hands of Lin Carter, who "edits" them for publication.
