[<< wikibooks] Greek Mythology/Titans
The Titans, often called as the Elder Gods, are the children of Uranus (Ορανος) . Their role/function was to oppose the gods run by Zeus and the other Olympians. They are not simply big gods. That role is for the Gigantes who came out of a god's blood. The Titans were involved in epic wars, many of which have been written about. Some sons of Titans include important gods like Prometheus and Atlas.
