Allied forces (House of Light, Imperial Cabal, Lucent Brood and Guardians) assault the Witness. Launch it from the campaign in the director after the prior Final Shape missions; it also has Replay, Narrative and Grandmaster variants (Grandmaster listed at power 2010, added June 2024 as the first non-Nightfall Grandmaster activity per Destinypedia).

Encounters

1. Territory: fight through the Witness's forces and claim zones to banish its influence.
2. Cornerstones: in the Witness's arena, kill the two Cornerstones (Taken) on either side.
3. Veiled Statues: enter the Witness's consciousness, collect Traveler's Light and destroy the statues with the sword.
4. Final phase: destroy the Glyphs on the Witness's body to expose its chest and damage it, dodging its hand attacks; repeat until the final stand.

Grandmaster adds Witness arms to shoot out (glowing orange bands) and more dangerous attacks.
