Delve the mountain deep! When the first dwarves reached the surface of Golarion, they built enormous keeps as a monument to their legacy and to serve as their new home. The mightiest of these keeps was Highhelm, a Sky Citadel deep in the Five Kings Mountains. While other Sky Citadels have fallen since the Quest for Sky, Highhelm holds strong, serving as one of the major centers of dwarven culture. Lost Omens Highhelm delves deep into the Emperor's Peak to present Highhelm in all its glory. This book details everyday life in the city, dwarven culture, and the various clans that influence the Sky Citadel. It also provides a full gazetteer of the city's layers and surroundings, each with adventuring locations and sites of intrigue suitable for a multitude of adventures. An included poster map presents Highhelm's layers in high detail and serves as an aid for campaigns centered on the dwarven city. Characters looking for new options can visit Highhelm for new equipment, ancestry feats, animal companions, and more!
