Starfield:One Small Step (MQ401e)

Walter greets you with a gun and some Ecliptic mercs. Apparently, an alternate version of Walter had become Starborn and proceeded to inform his counterpart in this universe to buy the Lodge and acquire the Artifacts. He will want to negotiate for the sale of the Artifacts and the charts gathered by Constellation. You will have the option to come back later, pay, or attack them, looting the Artifacts from Walter's corpse.
