Phoebe

In the mythology of classical Greece, Phoebe was one of the Titans, a group of godlike giants which predate the Olympian pantheon, and were ultimately supplanted by them.

Overview
One of the more obscure Titans, Phoebe was one of the first generation, and is most notable for giving birth to two of the second-generation Titanesses, Leto and Asteria, by her brother Coeus. These two in turn were the mothers of the Olympian gods Apollo, Artemis and Hecate. She was associated with the powers of divine prophecy but, like her siblings, does not appear to have been worshiped or prayed to in any significant way.

Phoebe was one of the Titans who participated in the Titanomachy, a ten year war waged by Zeus and his allies against their forebears for control of the universe. After their ultimate defeat, Phoebe and many of the other Titans were imprisoned in Tartarus, the Greek pit of damnation, for their transgressions.
