Concierge

Concierge is a Railroad radiant quest in Fallout 4.

Detailed walkthrough
After establishing a new safehouse for the Railroad, the Caretaker will request that the Sole Survivor clear a random location of its hostiles so that a synth, whose designation starts with K8, will be able to leave the Commonwealth safely. Once all enemies in the location have been killed, return to the Caretaker to complete the quest.
