The usual result of a human taking a runaway semitruck head-on is a very sudden, very fast track to the pearly gates. But for one newly noncorporeal man, there's another option: become a dungeon. Feeling sorry for the desperate angel assigned to him, the man relents. Heck, if it doesn't work out, he can always chat with Saint Peter about it later. Next thing you know, he's a dungeon. Admittedly, a small run-down, somewhat unimpressive dungeon (more of a house, actually), but you gotta start somewhere, right?

Try as he might, Fischer still can't catch a break. Tropica's forces have just perpetrated the fantasyland equivalent of crashing the king's party, kicking over the punch bowl, and making a series of rude gestures on their way out. Unfortunately, they're about to learn firsthand that when you take a bully down to the mat, it's best to make sure they don't get back up. Because their enemies are unearthing long-forgotten powers, and if those dabbling in the resulting destructive chi succeed, they could become even more annoying than the time Corporal Claws hid all of Fischer's pants.
