From the back of the book: Soaring above the characters’ heads at all times, the Spire is both awe-inspiring and daunting. Although often obscured by clouds, it poses an everpresent threat and a reminder of the region’s dark history. In this book you will find details about Goth Gulgamel, the fortress of Ghul: the Skull-King and Half God. It is a place of great evil and great power, of interest to high-level characters as a site to explore. You will also find a chapter describing Jabel Shammar, almost certainly the worst place in the world. Jabel Shammar is the fortress at the top of the Spire, built by the Dread One himself. You get a room-by-room description of the stronghold plus ideas for staging an exciting campaign climax there. Includes full-color maps of both fortresses. This is one in a series of nine Ptolus PDF releases from Malhavoc Press. When used together, they comprise the entirety of the Ptolus print book. Each one is also usable on its own for city-based fantasy d20 roleplaying campaigns.
