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
