Double the Adventure: More about The Black Monks of Glastonbury

Glastonbury, home of the first Christian church in Britain, has fallen to diabolic corruption from within. Now the house is run by black-robed Benedictine monks who praise Satan instead of God, and corruption spreads from its walls…

Take a stand against the black monks in this dual-system OGL and Ars Magica adventure supplement. Diabolism rules for both systems are provided, including the OGL Diabolist prestige class and Ars Magica rules for demonic gifts.

Journey beyond the adventure provided with a detailed background on the abbey and additional story hooks to help you build a lasting saga of your own after the scenario is completed.

The Black Monks of Glastonbury is out of print. This dual system supplement requires Ars Magica fourth edition or your favorite d20 system to play.
