Monolith

The Monolith is a structure in Destiny 2 belonging to The Witness. It is the setting of the Substratum encounter, the first encounter of the Salvation's Edge raid.

Overview

The Monolith is a tall structure with labyrinthine rooms on its lower levels. In Substratum, teams see looming statues holding it up over a vast pit. Teams clear rooms and complete the encounter's objectives, and then a staircase leading further into the Monolith unfurls from the ceiling. Teams must ascend it to reach the final confrontation with the Witness.

Keepers of the Monolith

The Keepers of the Monolith are Vex hydras of the Sol Divisive collective. They protect the Monolith on the Substratum levels and lock down doors that lead to the conductors teams need to advance. Teams must eliminate them to continue the encounter and ascend.
