Cosmic Catastrophe

A very large meteorite struck
Lucifer-1, in Quantum 7, about
100 years ago. Few traces of human
civilization survived. Continuing vol-
canism has rendered its air nearly
unbreathable in most areas.
Lucifer-3 is worse: the surface of
Earth – and quite possibly every world
within several hundred light years –
was sterilized by radiation from a
nearby supernova or gamma-ray
burster. Homeliners are systematically
looting the ruins of its TL7 human civ-
ilization for surviving art treasures
and refined raw materials.
On Taft-3, massive solar flares
caused sterility and a more gradual
collapse of civilization.
Few traces of
human civilization
survived.
