Calypso

Calypso is a third generation Titaness, a daughter of Atlas. As punishment for her support in the First Titanomachy, she was banished to Ogygia, a remote island where different heroes whom she couldn't help but fall in love with would end up. None of those heroes whom she falls for would ever be able to stay with her.

​​​​​​Early life
Calypso was born from Atlas and his grandmother Tethys. Though her parents never married, she developed a very close relationship with her father.

First Titanomachy
When the First Titan War began, Calypso was the only of her sisters to help her father, uncles, and cousins to fight against the gods. Though the Titans initially had the upper hand in the battles, since they were very skilled and much more experienced warriors, the gods quickly became skilled and experienced warriors as well, and with the help of their new extremely powerful weapons (Zeus' Master Bolt, Poseidon's Trident, and Hades' Helm of Darkness) and the aid of the Elder Cyclopes the gods finally prevailed.

During the final battle, Zeus and his siblings ascended to Mount Olympus (the tallest mountain in Greece after Mount Othrys), used his Master Bolt to shear off the top of Mount Othrys, and hurled Cronus from his black throne, defeating the Titan King. Shortly thereafter, the gods invaded the ruins of Mount Othrys, and finally overwhelmed the remaining Titans. In the aftermath of the battle, the Titans were all chained up by the Elder Cyclopes, after which the Hekatonkeries forced them to kneel before the gods. Only Kronos' mighty former second-in-command, Calypso's father, received a different punishment, as he was forced to hold up the sky while being chained to the ruins of Mount Othrys.

As punishment for her support of the Titans, Calypso was imprisoned in the phantom island Ogygia by the Fates. She cannot leave the island, but others can. As Hera felt pity, the gods gave Calypso several servants and will come to visit her every so often to bring the word of the outside world. Every thousand years or so, the gods of Olympus will send Calypso a "companion" (hero) to Ogygia so that Calypso will "tend to him and befriend him." All the heroes sent to her attract her, so she falls in love with them, but they will never stay and will end up breaking her heart.

The Odyssey
Calypso was the absolute ruler of the isle of Ogygia, where she imprisons the Greek hero Odysseus to make him her immortal husband. Calypso kept Odysseus on her island for seven years until Odysseus wished to return to his wife, Penelope, the queen of Ithaca.

Odysseus' patron goddess, Athena, asks Zeus to release Odysseus. Zeus complies and sends Hermes to tell Calypso to set Odysseus free. Calypso begrudgingly accepts this command and gives Odysseus the supplies he needs to make a raft home. Her winds allowed the hero to sail away to his destination safely. Unknown to Calypso, when he is an old man, Odysseus tries to find a way back to her, but his astrolabe lacks a vital crystal from Ogygia to make it work.
