you make your way down the stairs to the dungeon, 'gee this is the cleanest dungeon ive ever seen, i like an evil guy who is into cleaning'. you momentarily get over you unatural respect for the evil guys cleanliness, and get on your way. as you turn a corner, you come across a rather ugly, but clean looking troll. "you come for the princess!? i will show you the way!" says the troll
