Post-Tefarrs Summary: Used to be humans, living in the tefarn system, for several thousand years after the fall of Earth etc. Hostile alien force of unknown origin invades, using highly advanced psionic warfare. 95% of the Teffar people are almost instantly wiped out, only the ones who have high restitances to psionics survive, and avoid detection. Over the next 50 or so generations, the only teffars still alive are full immune to psionics, but unable to use any psionics themselves. Around 50,000 Teffars manage to escape the alien occupied planet in a single City-Ship, The survivors are put into a state of cryogenic sleep for close to a century while the ship continued on auto-pilot at speeds many times faster than light. The ship finally arrived at a suitable planet, and life continued for the Post Teffar people, with their capital based around the now landed City-Ship. However, fearing being invaded again by pursuing aliens, much of their future infrastructure was built into further city ships, that would be able to leave the ground and carry much of the Teffar population with them.
