In this part of the quest, you’ll be heading into the Gorge on Kepler to use the Rosetta device and track down another piece of the weapon. It’s a straightforward step, but you’ll still need to fight through some Vex and interact with the Command Module to move forward. This guide will walk you through each section step by step, so you know exactly what to do, where to go, and how to do it.
Triangulate the location of the weapon piece using the Rosetta device in the “Gorge”
After you’ve returned to the Emeritus and advanced the quest, your next stop will be the Gorge area on Kepler. To save time, fast travel straight to the Assimilated Easement. From there, simply follow the waypoint deeper into the Gorge. You’ll be making your way toward another Rosetta triangulation site, so keep an eye on your marker as you move through the area. When you arrive, you’ll find a Rosetta Vex Sentry Minotaur. Take it down first, because you won’t be able to interact with anything until the area is clear.
Access the Command Module
Once the fight is over, look for a small Vex structure on the far left side of the room. Behind it, you’ll find the terminal for the Command Module. Interact with it to trigger the next step of your quest and keep pushing forward toward that Graviton Spike Exotic Hand Cannon.
After you activate the Rosetta Device in the Gorge, your next task will be to track down the second piece of the Graviton Spike. Just follow the waypoint as it leads you deeper into the Stellar Sink. Keep going until you reach a Mattermorph node right before a big open space.
