Hestia

"Before she was the goddess of the hearth, she specialized in another type of fire."

- Lore

Hestia, in Greek religion, goddess of the hearth, daughter of Cronus and Rhea, and one of the 12 Olympian deities. When the gods Apollo and Poseidon became suitors for her hand she swore to remain a maiden forever, whereupon Zeus, the king of the gods, bestowed upon her the honour of presiding over all sacrifices.

She was worshipped chiefly as goddess of the family hearth; but, as the city union was only the family union on a large scale, she had also, at least in some states, a public cult at the civic hearth in the prytaneion, or town hall. Hestia was closely connected with Zeus, god of the family in its external relation of hospitality and its internal unity. She was also associated with Hermes, the two representing domestic life on the one hand, and business and outdoor life on the other. In later philosophy Hestia became the hearth goddess of the universe.

Hades
At some point during the war between the Olympians and the Titans, Hestia wielded the Adamant Rail against her enemies.
