This site was never completed, as I started work on a new campaign booklet instead, for easier reference at the table. So this website will probably eventually be replaced with that. You might be able to find some of that campaign stuff on demonidol.com in the future. – David, July 1, 2025

The Geb campaign is a Advanced Dungeons & Dragons by-the-book (BTB) campaign that began in August 2022. This website is a resource for participants in that campaign, as well as a reference for anyone looking for inspiration in developing their own milieu.

Geb is the home of the Demon Idol AD&D interpretation.

Players: If you're new, it's time read the Campaign Primer.

“When you build your campaign you will tailor it to suit your personal tastes. In the heat of play it will slowly evolve into a compound of your personality and those of your better participants, a superior alloy.” – DMG 7
