Liege Killer

Two hundred years after a nuclear apocalypse forced humanity to flee Earth, stories are still told about the Paratwa - fearsome genetically modified killers who occupied two bodies, controlled by a single vicious mind. The legendary Paratwa Reemul, known as the Liege-Killer, was the strongest of them all.
Now someone has revived Reemul from stasis and sent him to terrorize the peaceful orbital colonies of Earth. Is this an isolated incident, or has the one who unleashed this terrible power announced a gambit for control over the entire human race?
