The world ended with no warning, and all that was left ... was hope.

The Cylons were created by the people of the Twelve Colonies. Intelligent robots, they were used as slaves and soldiers to fight humanity's wars. But the Cylons became sentient and they rebelled. Man and machine fought to a bloody stalemate, then the Cylons withdrew to a remote region of space.

In one devastating day, billions of human lives were consumed by nuclear fires. Only those souls fortunate enough to be aboard starships were able to band together and escape and flee into deep space, led by the sole surviving Colonial warship, the battlestar Galactica.
