One million years ago, the Celestials collected the Wanderers (Homo erectus) during their first Host on Earth. Gammenon the Gatherer collected the ape-men and send them to Ziran the Tester. Ziran mutated them to have an unstable genome, creating the Deviants (Homo descendus). The Deviants became a race with destabilized DNA producing various mutations, who were then released and went hiding in caves.
