Preston Garvey is the monitor of the Boston Volunteers (militia). He will initially appear with a group of volunteer survivors in the public library of Concord Town. If Preston Garvey chooses to help volunteers in Concord, he can go to Mount Serto (where the hero lived before the war) to live permanently. At this time, Shelter Hill will become the main stronghold of the volunteers. He wants to take Preston Garvey with him in his daily tasks and ask him to pick him up. You can find him in the shelter mountain (if you think there are too many people in the shelter mountain to make trouble, you can set up a bell in the open space of the shelter mountain and call everyone with a bell every time you want to find someone).
