History of Declassification (activity)

Overview

Declassification is the final Kepler side quest from Ikora Rey in Destiny 2: The Edge of Fate, with Lodi assisting. Void readings reveal microscopic singularities, caused by axion bolts that must be destroyed. It was held back at launch and enabled by a later patch.

Requirements

Sources disagree: Destinypedia says finishing the "Quarantine" story mission unlocks it; ProGameTalk says you first need the Gorge Strangelet quest and Ikora's other Kepler side quests. Do those first to be safe.

Steps

1. Follow Void signals to marked spots in The Stacks (near a reactor) and interact with the briefcase; destroy the axion bolts.
2. Repeat at the next marker, then the next singularity.
3. Track the final readings to the wreck of the Ares One ship.
4. Defend it from Vex who arrive.

Rewards

Destinypedia lists 3 Fated Ciphers plus an AION Renewal armor piece or a Kepler weapon; ProGameTalk says Legendary gear and a Fated Cipher. Related: the "Kepler Tasks" triumph.
