The Echoes of the Past mission in Starfield represents one of the most pivotal moments during the Crimson Fleet storyline. Taking place in the bleak, icy expanse of Suvorov, this operation sends players deep into the abandoned supermax facility known as The Lock. As players navigate through frozen corridors and dangerous local fauna, they must uncover critical historical leads while making decisions that impact their relationships with faction members.

Infiltrating The Lock on Suvorov

Upon landing on Suvorov, players team up with Crimson Fleet leader Delgado and recruit Mathis Castillo. Before gaining access to the main complex, the squad must defeat a swarm of hostile subterranean creatures called Grylloba that infest the surface. Once inside, structural cave-ins separate the team, forcing players to pair up exclusively with Mathis to restore power and navigate the crumbling layout.

Navigating the Cell Blocks and Uncovering Intel

To access Jasper Kryx's original cell, players need to reach the security control room and manually release the lockdown. Searching the designated cell reveals a hidden audio slate tucked beneath a desk lamp, which outlines Kryx's escape route and points toward additional evidence. Following these clues leads players through maintenance ducts and shower areas to locate Carter's locker and crucial audio records.

Key Decisions and Mathis' Fate

During the trek through the facility, Mathis proposes a mutinous plan to eliminate Delgado and claim the legendary treasure for themselves. Players can choose whether to endorse his conspiracy during the journey or reject his scheme outright. The critical choice occurs upon returning to Delgado, where choosing to report Mathis' incompetence results in his expulsion from the fleet, while supporting him enables him to be recruited later as a companion.

Escaping the Shuttle Bay and Reporting Back

After reaching the Warden's office and opening the flight hangar, players are ambushed by a massive Grylloba Queen. Defeating the boss allows the player to secure a prison shuttle and navigate back to The Key to complete the mission. Before moving to the next phase of the campaign, undercover players must debrief Commander Ikande on the UC Vigilance to update United Colonies intelligence on the fleet's motives.
