As for Xemu, the Loyal Officers overthrew him and locked him away in a mountain on one of the planets. He is kept in by a force-field powered by an eternal battery and Xemu is still alive today.

This comes from a cult pamphlet which believes Xemu can break free. Do not worry internet traveller, the arrival of the Green One stopped the explosion of Planet Mythos. We are not cultists, we do not worship Xemu, and Xemu will not escape the past while the Green One protects us. And if any of us die along the way, Port Authority can regenerate a new body for us using the new Düp 'O' Vat cloning process. Feel better now?
