"There's some kind of magic path leads up the mountain," Willie went on. "But there's a mass of caves before you get there."

Willie looked impressed. "Heard of them, have you? Accordin' to some old legend they're guarded by a legion of fearsome monsters and some devilishly devious devices and no one has ever passed through. Oh, yeah... perilous crevasses, too. Next, we'll have to swim through underwater caverns guarded by giant man-eating fish that no man has ever yet passed. And then there's some insane monks, and a door you can pass only by solving some ancient riddle... the usual sort of stuff."
