The Sigil of Jerusalem is a massive Adventure Module, spanning levels 1 to 10, filled with massive dungeons, legendary NPCs, immersive handouts and soundtracks and a deep and branching storyline. 

The year is 1182, and the Crusades came to a halt as an unexpected truce was struck between Baldwin and Saladin. Hidden behind this peace is an occult war, against an eldritch threat, awakening deep below in the catacombs of Jerusalem and the dunes of Cairo.
