I'm trying to think of this as simply borrowing a convention. I think that this basic structure could help, since there's only one town right now, for going back, selling items, updating quests, etc.
I haven't marked these yet, but I tried to make them make sense to me.

Modified! I added graphics and clickable hotspots as well as some descriptive messages. Each end of the warp point now uses two events - on the "close" end, one event to tell you the warp point isn't active yet, and one to actually warp you, and on the "far" end, one event to activate the warp point, and one to actually warp you.
