Hestia

Hestia, daughter of Cronus and Rhea. Rhea is the goddess of Earth and almost everything, so she was one of the first goddesses in Mount Olympus. Cronus is a titan, a very evil one and most probably the leader of the titans, gave birth to Hestia. Goddess of homes, the hearth, cooking and fire. She can cause natural disasters like volcano eruptions and can do much harm if she's angry. 

Personality

Hestia is one of the lead goddesses, very major but not up to the century. She can control fire, so she has an unpredictable and demanding personality. She likes to take care and watch over homes.

Other

When Hestia was a baby, Cronus was horrified and decided to swallow her. Rhea was very shocked at this, and to Cronus' surprise she confronted him to Zeus. Zeus let Hestia live and grow in Mount Olympus, where she can be safe to such a villain like Cronus.
