Fetch the Glitch Artifact is a quest given by Esther after turning in Find Clues to Locate the Glitch Artifact, having scanned enough clues to unlock the location of the artifact.
Players can travel to the Baron's Keep from the missions tab in their ship computer. They can use this interface to return to the mission at any time in the future to replay it.
The artifact is at the end of an Glitch facility, the Baron's Keep. There are a number of cultists throughout, and players must also defeat a boss at the end of the mission; Bone Dragon. They'll also encounter a friendly Glitch who will join them at the outpost after the mission has been cleared, The Baron.
After defeating Bone Dragon the path to the artifact is unlocked and players can recover it and return to Esther. The Baron will also join her at the Ark.
This quest unlocks Opening the Ark.
