Kobolians are a race of humans who left their home planet for the stars. They founded twelve planets nearby of which Caprica is one of them. The thirteenth planet is called Earth. The inhabitants are Earth human in form, there are no differences, nothing to tell us and them apart.
The whole twelve tribes of man is based on the Old Testaments story of Jacob's sons. Each tribe in the series is based after a Zodiac sign, Aerelon, Aquaria, Canceron, Caprica, Gemenon, Leonon, Libron, Picon, Sagittaron, Scorpion, Tauron and Virgon. The Colonial Fleet Headquarters are on Picon.
