4 Vesta is the second largest asteroid in the asteroid belt.
The Awoken have incorporated Vesta into the Vestian Web - the heart of Awoken civilization in the Reef and from where Queen Mara Sov rules her domain.  Just outside the Vestian Web lies the Vestian Outpost, a space station built from a Fallen Ketch and the asteroid 5560 Amytis, where outsiders are permitted to enter the Awoken realm. The Prison of Elders is located nearby.
