S1: Tomb of Horrors (1978)

From the front cover:

AN ADVENTURE FOR CHARACTER LEVELS 10–14

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.

This module was originally used for the Official ADVANCED DUNGEONS & DRAGONS® tournament at Origins 1. The author wishes to thank Mr. Alan Lucien who was kind enough to submit some of the ideas for this dungeon.

Included herein are background information, the Legend of the Tomb, and possible locations for the tomb on the WORLD OF GREYHAWK™ map. Also included are DM notes, characters specially designed for the module, and numerous illustrations to be shown to the players.
