Nemesis

Tearing its way through space on a collision course for Earth is NEMESIS, a fiery ball of destruction, a dwarf star as red as the colour of blood.

Circling Nemesis is ROTOR, an Earth colony whose only occupants have cut themselves off from the anarchy and degeneration of an old and wasted world.

For them ROTOR is a kind of Ark.

And NEMESIS is the Flood.
