Kobol

Kobol is a planet in the fictional Battlestar Galactica universe.

Within the context of both Battlestar Galactica stories, Kobol is the birthplace and original home of humanity, from which the civilization departed and formed the Twelve Colonies on other worlds. According to legend, there was also a thirteenth tribe who settled on a "lost" colony, a planet called Earth, whose location remained a mystery to the populations of the other twelve.
