Crew of Exiles

In 2500 A.D. an immortal has ended its own life. Beryl, a misanthropic transcendent being, is accused of assisting in the suicide. Banished to a human body by his peers, Beryl is sentenced to a 1,000-year exile on the depopulated Earth.

Beryl is certain the exile will drive him insane if he can't figure out a cheat. But getting dragged along on an adventure by the few remaining earthlings isn't exactly what he had in mind.
