There is a secret maze somewhere, I used to know where it was but they built over it, that is most likely what it is
No, I know what it is now, I think. When they cleared land for the new spawn, homes under it where they didn't build were left there. My best guess is that that is somebody's old underground storage room, and their house would have been right on top of it. The new spawn is in thw old town of " Wake Forest " so that would make sense.
