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.

The colony of Farshore has survived on its own for years, a secluded and struggling hamlet perched on the western shore of the tiny island of Temute.

"The longest, and perhaps strongest, AD&D adventure we've ever done." The fabled Mace of St. Cuthbert has been lost from the sight of both human and demi-human for many centuries. Some claim it lies at the heart of an active volcano, guarded by salamanders and flowing lava; others swear it lies buried deep inside the earth, warded by powerful magics raised by those who would see its power denied to the forces of Law and Good. A few assert that it has never left the possession of the Saint, and even now he holds it in his strong right hand. But a few claim that none of these are so that long before the Sainted Cuthbert rose to his exalted station, his mace was hidden away from those who would steal it before he returned for it, hidden away outside the bounds of normal time and space, in a place so outlandish that the Mace's power and destiny would be unknown and unknowable, and thus safe. Pgs. 45-54 & 56-57 & 59-68

Once the supreme master of all undead sorcerers, even today his Hand and Eye are object of immense power. Now something evil is stirring in the lands around Greyhawk.

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. Furthermore, the demi-lich has so well hidden his lair, that even those who avoid the pitfalls will not be likely to locale their true goal. In the far reaches of the world, under a lost and lonely hill, lies the sinister TOMB OF HORRORS. This Labyrinthine crypt is filled with terrible traps, strange and ferocious monsters, rich and magical treasures, and somewhere within rests the evil Demi-Lich. TSR 9022
