"Hell" is the name commonly given to the largest area in the game, also known as the "Red Maze". It contains several links to other places, as
well as a few areas not reachable by any other means. Its exploration is necessary for at least one of the effects.
This is one of the few places you can get a "Heart" and links to many maps. Oftentimes maps leading here have Toriningen blocking the way. There is also an event that can be triggered here somewhere.
