Time travel; Science Fiction
Rigg, Param, and Umbo have combined their abilities to slip through time and escaped from their deadly pursuers, circumventing the impassable Wall that separates their planet into nineteen independent evolutionary experiments. As they travel through these strange environments, a warning from the future tells them that ships from Earth are about to revisit their time-displaced colony and will destroy the current inhabitants. The group spends a year travelling and meeting people to learn about the past in order to change the future. When the ships arrive, Rigg kills the pilot but ends up needing him alive to save the planet. Rigg then travels back in time to stop himself, creating a double of himself in the process.
