After Zeus established himself as supreme monarch of the Olympus and the Olympian gods, Vesta became the domestic engineer of Olympus. She was assisted in her tasks by her cousin, the Titan Prometheus. Prometheus, however, had developed great affection for the ancient Greeks who worshipped the Olympians which eventually led him to steal the fire of the gods and give a portion of it to mortal man. Vesta was aware of Prometheus' actions but turned a blind eye to them. Prometheus ended up being punished by Zeus for his conduct for several millennia before eventually being rescued by the demigod son of Zeus, Hercules. At one point, Vesta was desired by both Apollo and Neptune. In response to this she swore a vow of chastity to Zeus which he honoured even today. 

Vesta once was a member of the ruling council of Olympian gods which was comprised of Zeus, Hera, Neptune, Demeter, and Vesta, together with Zeus's children Apollo, Ares, Artemis, Athena, Hephaestus, Hermes, and Venus. She later resigned her seat at the high table in favour of Zeus' son, her nephew Dionysus, who then became one of the twelve great Olympian gods. It was said she did so because she grew tired of the gods' petty bickerings during council meetings. Her worship under the name of Vesta (as she was named Hestia at birth and was so worshipped in Greece) carried over to the ancient Romans after the survivors of the fallen city of Troy travelled to the lands of Italy. Under the name of Vesta, she had numerous priestesses called the Vestal Virgins who paid her homage and tribute to her ancient vow of chastity. 

(Thor I#301) - Vesta was present when the Asgardian Thor came to Olympus, asking Zeus' help in reviving the Asgardians slain in battle with the Celestials.

(Hercules III#4 - BTS) - Vesta was possibly present with the Olympian pantheon as they convened a board meeting on Earth at the Olympus Group, assuming the appearances of mortal businessmen in an attempt to maintain some connection with humanity. Zeus had gathered them to confront Hera for manipulating Hercules into appearing on a reality television show as part of an attempt to gain revenge upon him, but he wound up being jeered at by his own family for his many infidelities. They finally voted against interfering with Hercules' labors.

(Hercules: Fall of an Avenger#1 - BTS) - Athena led the Olympus Group including Hestia to the funeral of Hercules.
