Slow Empire
From Tardis Wiki, the free Doctor Who reference
The Slow Empire was an empire established millions of years ago by a humanoid race of unknown origin.
History
The founders of the empire designed a method of travel known as Transference. They sent out probe ships carrying, in stasis, condemned psychopaths who had been lobotomised and "cyberdynically" implanted with controls. On arrival on a habitable planet, they would set up transference engines and then die on the spot. This expanded the empire across a vast space. (EDA: The Slow Empire)
