|Destruction of Reptillian Cylons
|Sometime before Thousand-Yahren War
|Somewhere in Cyrannus Galaxy
(probably a Cylon Homeworld)
|Robotic Cylons' Victory, All Reptillian Cylons are dead
Originally, the reptilian, serpent Cylons created a race of robots to service their needs and then they created the ultimate in machinery technology, the ruler known as the Imperious Leader. But due to a slight error in their programming, the Imperious Leader turned against his creators and ordered his subjects to exterminate all human life forms. Thus began a war with the Cylon Centurions that erased all of the human race in the star system. Reptillian Cylons were killed by Robotic Cylons and leaving behind a race of supermachines. Their robotic creations still bear their name.
