Deep beneath the keep of Castle Greyhawk, a really nasty device is creating mutated, unpleasant monsters that are running wild throughout the castle and the twelve-level dungeon beneath. The call has gone out for heroic, fearless, and perhaps foolish adventures 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 find the nasty monster creator and put it out of business. Castle Greyhawkcontains 13 detailed levels for adventuring and exploration. Each is a separate adventure written by different author and each has its own unique brand of baffling weirdness. Some levels involve solving puzzles and some require good old hacking and slashing. The adventure 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 of this dungeon is that no joke is so old, no pun so bad, and no schtick so obvious that it can't be used to confuse and trip up PCs! 13 Adventures for Character Levels 0 to 25.

Somewhere under a lost and lonely hill of grim and foreboding aspect lies a labyrinthine crypt. It is filled with terrible traps and not a few strange and ferocious monsters to slay the unwary. It is filled with rich treasures both precious and magical, but in addition to the aforementioned guardians, there is said to be a demilich who still wards his final haunt (Be warned that tales told have it that this being possesses powers which make him nearly undefeatable). Accounts relate that it is quite unlikely that any adventurers will ever find the chamber where the demilich Acererak lingers, for the passages and rooms of the Tomb are fraught with terrible traps, poison gases, and magical protections.

Not even memories of past glory live on in the gentle hills around the village of Kusnir. Today its people have more concern for commonplace things, like the harvest, trade, and the threat of death in the night! Kusnir is beset by a skulk. The attentions of such a creature are a curse on any community. Streets and alleys which ring to the voices of children by day become fearful, shadowy places by night. Men go abroad armed and in groups, while women and children stay behind locked doors and even there are not safe. But life goes on. The lot of the peasant is always hard, what cannot be prevented must be endured and, of course, things could be worse. Much worse. The skulk has begun to visit the village more and more often. Sometimes it kills, yet just as often it spares a victim, leaving clear signs of what it might have done had it wished. Its visits are now marked by strange and illegible symbols scrawled in blood on the walls of the buildings. The people are worried, helpless, and desperate. Desperate enough to welcome adventurers.
