History of Darkest Depths

Overview

Darkest Depths is a Triumph on the Moon that requires finding the Hive book in the Catacombs. It is tied to the Oblation exotic missions, and only a progress tracker is listed.

How to complete

1. Complete all three Oblation exotic missions: Oblation Bloodline, Oblation Soulfed and Oblation Immolation. Their rewards include the Cull's Shadow exotic and its catalysts.
2. Go to the Moon and follow the Catacombs to the end.
3. Stand on a Hive plate to form a bridge, then cross it to the Hive pedestal holding the Oblation book.
4. Interact with the book to claim the triumph.

Tip: Oblation can also be started as a timed Legendary run. All three missions must be finished within 30 minutes, and the timer cannot be extended. Completing the separate That's a New PB triumph during the timed run rewards the Oblation II Emblem.
