Somewhere under the 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 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 the 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 demilich has so well hidden his lair that even those who avoid the pitfalls will not be likely to locate their true goal. So only large and well prepared parties of the bravest and strongest should even consider the attempt, and if they do locate the tomb they must be prepared to fail.
