Forgotten Deep

The Forgotten Deep is one of three Lost Sectors in the Pale Heart, with The Broken Deep and The Blooming Deep, added with The Final Shape. The Pale Heart's Lost Sectors are in The Landing, and the Forgotten Deep is fought with Hive enemies.

Its final boss is Ei, Räkosh, Banisher of Memory, a Lightbearer Wizard. The boss guards a locked orange chest, which opens for rewards once the boss is defeated.

Rewards on Legend difficulty have been reported differently across sources and years, with some listing Exotic armor and others saying Exotic drops have been limited since The Final Shape. Check the current rotation before farming it.
