Hestia

Hestia is the Olympian goddess of the hearth, domestic life, virginity, the home and the state. She is the eldest child of Cronus and Rhea.

Hestia decided to remain a virgin goddess after witnessing the stress put upon her family by marriage and disloyalty when it came to love. She was also the goddess partially responsible for giving Prometheus fire, which was soon given to humanity. However, she was soon resurrected by Hades shortly before his own death at the hands of Deicidia.

Birth and Rescue
Hestia was the oldest child of Cronus, the Titan-King of Mount Othrys, and his wife, Rhea. When she was born, Cronus was initially willing to be a good father until he realized that Hestia wasn't a Titaness, but a more powerful and beautiful immortal (a goddess) and therefore had the potential to overpower him one day. Fearing the possibility, Cronus quickly swallowed her whole - much to Rhea's horror. However, as an immortal goddess who couldn't truly die, Hestia wasn't killed or destroyed by her father's swallowing her whole, and instead spent her childhood undigested in her father's stomach. She was later joined by her younger siblings (Demeter, Hera, Hades, and Poseidon), all of whom were also swallowed shortly after their birth.

Ultimately, Rhea gave birth to her sixth and final child, Zeus, whom she hid away and secretly raised on Crete with Gaia's aid, faraway from Mount Othrys. In place of Zeus, she gave a huge boulder as a decoy for the tired Cronus to eat. After he reached his maturity, Zeus successfully infiltrated Cronus' Palace on Mount Othrys as the Titan-King's new royal cupbearer. Hestia was finally released during the final drinking competition Cronus had with his Titan brothers and nephews, for Zeus poured a potent emetic into Cronus' goblet, which caused the Titan-King to disgorge all the contents of his stomach in reverse order of swallowing. First the boulder, then Poseidon, Hades, Hera, Demeter, and finally Hestia herself. Zeus quickly introduced himself to his elder siblings and all of them quickly escaped Mount Othrys before their father and their Titanic relatives could react.

In Zeus' cave at Mount Ida, Hestia and the other gods accepted Zeus as their leader, and though she initially suggested diplomacy, she was finally convinced to agree with her younger siblings about declaring war against their tyrannical father. Hestia was happily reunited with her mother Rhea, who tearfully embraced her and her siblings and recommended their releasing their Elder Cyclopes and Hekatonkeries uncles from Tartarus first, for the Hekatonkeries could serve as strong allies in their battle and the Elder Cyclopes could forge excellent weapons.

Rescuing the Elder Cyclopes and Hekatonkeries
Her brother, Hades, turned out to be skillful in navigating under the earth and lead them all into Tartarus through a network of Underworld tunnels. There, imprisoned in the maximum-security zone, surrounded by huge bronze walls, and a lava moat, were the Elder Cyclopes and Hekatonkeries. Their guardian Kampê was the most ferocious and fearsome monster in all of Tartarus.

However, the gods overcame their fear and were able to sneak in. Zeus managed to talk to the Cyclops Brontes and convinced him to forge powerful weapons for him and his siblings behind Kampê's back. The three Elder Cyclopes forged three incredibly powerful weapons: the Master Bolt (for Zeus), the Trident (for Poseidon), and the Helm of Darkness (for Hades). With these new weapons, Zeus killed Kampê and Poseidon shattered the chains of the Elder Cyclopes and Hekatonkeries, releasing them. Afterwards, Hades safely guided his siblings and uncles back out of Tartarus. In return for their release, all six of her uncles agreed to fight on the gods' side in the upcoming war with the Titans.

The First Titanomachy
Shortly after their return from Tartarus, Hestia and her siblings officially declared war on Cronus and the other Titans, which resulted in the terrifying 11-year-long Titanomachy. The Titans initially had the upper hand since they were well-armed and much more experienced warriors. However, as the years passed, the gods quickly became skilled warriors as well, and with the help of their new extremely powerful weapons and the aid of the Elder Cyclopes and Hekatonkeries, they finally prevailed.

While preparing for the final battle of the War, Hestia and her siblings ascended to Mount Olympus (the tallest mountain in Greece after Mount Othrys). During the final battle, Zeus used his Master Bolt to shear off the top of Mount Othrys and hurl Cronus from his throne, defeating the Titan King. Shortly thereafter, the gods invaded the ruins of Mount Othrys and finally overwhelmed Atlas, Hyperion, Iapetus, Crius, and Coeus.

In the aftermath of the battle, the Elder Cyclopes chained up all of the defeated Titans, while the Hekatonkeries forced them to kneel before the gods. Zeus took their father's Scythe, sliced Cronus into a thousand pieces, and then cast him into Tartarus along with the rest of his followers (except for Atlas, who was forced to hold the sky). The gods chose Olympus as their official residence and the Elder Cyclopes built magnificent palaces there for them all. As a result, the gods started to call themselves the Olympians.

Incident with Priapus
While celebrating the anniversary of her children's victory over the Titans, Rhea organized a grandiose party on Mount Ida on Crete. All gods and neutral Titans were invited, as well as many nymphs and satyrs. After drinking, Hestia wandered out into the woods and fell asleep. Priapus, a minor god of vegetation who possessed an abnormally massive phallus, spotted the beautiful goddess and hoped to take advantage of her. However, as he prepared to mount her, she was awakened by a donkey's loud braying. She screamed, and Priapus immediately fled. Hestia designated the donkey as her sacred animal thereafter.

Prometheus' Punishment
After the war, Hestia decided to become the Goddess of the Hearth and Family. She secretly allowed Prometheus to take some sacred fire from the Olympian hearth, as he desired to give it to humans. Despite this, no member of her family suspected her (or at least, they didn't punish her).

Feeling bad for Prometheus' severe punishment, Hestia protected every mortal pursued, attacked or in trouble if they made it to either a house's or a town's hearth. People of that household or city would be obliged or honor-bound to help and protect them if they asked for it.
