Take that and make it the length of the tunnels below Mithalas and you'll have the right idea.

(It's the area before the final boss, in the actual game.) I quite like the image of Naija slamming the door hard behind her - it reminds me of the classic, almost cliched, scene where the hero closes the door behind him only to encounter an even worse enemy (the Creator) in his "safe" haven.

However, the Gauntlet was actually harder than the Creator for me.
