The Environs of Aufstrag
A system-neutral setting supplement describing the lands surrounding the dread tower of Aufstrag in the world of Aihrde. Once verdant and ruled by the Aenochians, the region is now overgrown and hostile, including the swamps of Grausumland, the dead plains of the Toten Fields, and the Blighted Screed. The book details the area’s history, terrain, roads, waterways, peoples, and monsters, along with adventure hooks for exploring the remnants of Unklar’s rule. It also covers most of the locations featured in the A-series adventure modules.
