I have started the game and gotten into the temple area back by "The Machine" (The big round room) but can't find where to go from here! Any help would be awesome!
edit: Ok, I'm in the Old Temple, I have gone back and forth through the entire thing for more than an hour and can't find where to go from here. I have gone back outside and can't find any way to find the mainland.

The first dungeon`?In the room with the machine go to the bottom level and through the tunnel.

Oh my word, thank you! I was about to give up completely.
