The twelve giant offspring of GAIA and URANUS, they come in brother-sister pairs: CRONUS and RHEA, OCEANUS and TETHYS, HYPERION and THEA, COEUS and PHOEBE — all happily married to each other — plus the singletons IAPETUS, THEMIS, CRIUS and MNEMOSYNE who prefer to keep their options open. (The six sisters are also called the TITANIDES, by the way.)
After the deed was done, CRONUS and RHEA ruled over the Gods and the world entered a Golden Age of peace and prosperity. A second generation of TITANS was born — GAIA’s grandchildren: HELIOS, EOS, SELENE, ASTERIA, LETO, LELANTUS, ATLAS, PROMETHEUS, EPIMETHEUS, MENOETIUS, METIS, ASTRAEUS, PALLAS, PERSES.
Of course this Golden Age of bliss didn’t last. The following generation of deities — the Olympian Gods — warred against them and a disgruntled ZEUS banished them all to Tartarus Prison.
