From Destinypedia, the Destiny wiki
The Sunken Cavern is an underground sector beneath Exodus Black in the Arcadian Valley on Nessus. The cavern inhabits several Vex chambers, connected through floating rocks in the center of a deep pit.
This sector is accessible on the south-eastern side via a tunnel system from the east side of Exodus Black, past a Vex portal, that would lead to the Chamber of Sky, and on the north-eastern side from the north-east of the Hallows.
On the west side lower levels is a gateway, that leads to an active Vex portal. This teleports to a small cavern, with another Vex portal, which teleports to the Well of Giants, but is only active during the mission Looped.
