Tomb of Horrors is an adventure module written by Gary Gygax for the Dungeons & Dragons (D&D) role-playing game. It was originally written for and used at the 1975 Origins 1 convention. Gygax designed the adventure both to challenge the skill of expert players in his own campaign, and to test players who boasted of having mighty player characters able to best any challenge. The module, coded S1, was the first in the S-series, or special series of modules. Several versions of the adventure have been published, the first in 1978.
The module's plot revolves around the tomb of Acererak the Demi-Lich. The player characters must battle their way past a variety of monsters and traps, with the ultimate goal of destroying Acererak. Tomb of Horrors is considered one of the greatest Dungeons & Dragons modules of all time, as well as one of the most difficult.
Ready Player One History
In order to obtain the Copper Key, an avatar must complete a recreation of the Tomb of Horrors on Ludus, and approach Acererak. Instead of defeating him in combat, however, an avatar will face him in a best-of-three round of Joust. A victorious avatar will receive a copy of the Copper Key; a defeated avatar will be killed or badly injured.
The Tomb of Horrors is the first place the main character Parzival meets Art3mis, his love interest. Aech finds it shortly after Art3mis and Parzival. Later, the Sixers surround it with a forcefield, which is broken by an antimatter bomb by the gunter clans.
