History of Well of Flame

Well of Flame is a private sector of Arcadian Valley on Nessus, entered only from The Cistern.

Features

Multiple Vex teleporters direct players back toward the exit. The Flame Arena is normally sealed by an energy barrier but opens during the adventure "Invitation from the Emperor", where Cabal enemies are fought. A hole in the first chamber leads to a dead end with a Vex portal. The Destiny 2 Wiki reports no chests, material nodes or patrol beacons here.

Enemies

Destinypedia lists Red Legion, Sol Collective, House of Dusk and the Nessian Schism (during Episode: Echoes); it also links the area to the Aqueducts.
