The Timegod
Drawing on Norse legend, these books follow the story of the time-traveling Immortals of Query & their two greatest heroes--who both save & doom their people: The Fires of Paratime (1982) Timediver's Dawn (1992) The Timegod (1993) (republication of The Fires of Paratime) Timegod's World (2001) Omnibus. Lovi, a young timediver, becomes a full-fledged member of the Temporal Guard of the planet Query, but he soon rebels against the parasitic culture in which he lives.
