The quest begins the next time a save is loaded after purchasing the Creation Club content. The quest's objective is to find the Charlestown condo, which is in the mid-eastern part of the map, just east of Bunker Hill, and immediately adjacent to the USS Constitution.
After finding the door in the corner of a building, by the water, and under some vines, the quest will update with a prompt to search the nearby area to find any clues of where the key might be. There is a hollowed-out rock in some nearby rubble with a note inside, titled Note to travelers.
After reading this note, the quest updates and has the player character find someone named Charlie, who has the Charlestown condo key. His body can be found just up the street to the west of Hubris Comics.
Once the key is retrieved, the quest will have the player character return to the condo, where the workshop must be activated to complete the quest. The workshop is on the second floor.
