Deep beneath the keep of Castle Greyhawk, a really nasty device is creating all these gross, mutated, andd unpleasant monsters that are running wild throughout the castle and the 12-level dungeon beneath the castle. The call has gone out for heroic, fearless, and kinda foolish adventurers to out-hack, out-slash, and sometimes even out-think hordes of doughmen, headless mice, manic bee queens, really bad dead things, burgermen, crazed chefs, and movie moguls. If they survive these and much odder obstacles, the characters still have to findd the nasty monster creator and put it out of business.
Castle Greyhawk contains 13 detailed levels for adventuring and exploration. Each level is a separate adventure written by a different author and each has its own unique brand of insane and baffling weirdness. Some levels involve solving puzzles and some require good old hacking and slashing. The adventures can be played separately or all together as a grand quest to free Castle Greyhawk from the evil, rotten hordes that are plaguing it. The common theme to this dungeon is that no joke is so old, no pun is so bad, and no schtick is so obvious that it can't be used to confuse and trip up PCs!
