Demeter

Demeter is the daughter of Rhea and Kronos and sister of Zeus, Poseidon, Hades, Hera, and Hestia.

History
Shortly after her birth, Demeter was eaten by her father and began to grow within him. Later, she was freed by her brother, Zeus. She later participated in the Titanomachy, joining her siblings and overthrowing their father, Kronos.

Many years later, an uprising began by King Acrisius. Demeter, along with the other gods, wanted to lay waste to Acrisius' warriors. Demeter gained a nephew when Zeus had a child with Danae. About twenty years later, Demeter sided with others to just make peace with the other humans. However, her brother, Hades told Zeus to let him loose upon the mortals and made them pay for destroying their temples.
