History of Pools of Luminance

Pools of Luminance is a sector in Arcadian Valley on Nessus. Its main connection is a narrow corridor through a Vex structure at the southwest end, which leads to The Cistern. Unless Story Mission Six is active, this corridor is the only way in or out.

Inside, players cross the Radiolarian Stream by hopping between rocks while avoiding the Radiolarian. A golden alcove to the south holds a scannable object. Past the stream is the Radiolarian Cavern, the first area with enemy Vex, including Goblins, Hobgoblins, Harpies and Minotaurs.

At the far end is the Luminance Arena. During Story Mission Six, players fight strong Vex forces, including a Hydra, to help Cayde-6 escape a teleportation loop. A second scannable object sits below arena level near its northwestern edge. After clearing the arena, players can use a Vex Teleport, which drops them near the sector entrance.

The crystals resemble those in the Vault of Glass and on Atheon, and project a star map onto the adjacent wall. The sector first appeared in Destiny 2 and returns in Season of Dawn, Episode: Echoes and Reclamation.
