From publisher blurb:
Citadel on the Wilderlands is a flavour-rich mini-campaign setting designed for low-level characters intent on wilderness exploration and dungeon delving.
An isolated point of light amid the savage dark of the Wilderlands, Solonor Island—a haven and bulwark for humanity and its allies—is ever in need of heroes to push back the forces of evil seeking to overwhelm it. Scores of miles from the nearest friendly port, the Citadel on the Wilderlands and Solonor Island are a rare safe harbour on the storm-wracked, danger-haunted Skeleton Coast. Civilisation’s light has never burned bright in this part of the world. Trackless forests, rugged hills, noisome mires and sodden moors run along the Skeleton Coast. Further inland, the mysterious, rumour-choked rock pillars of the Gray Spires thrust skywards as they have since time immemorial.
Opportunities for gold, glory, and death gather thick upon the Skeleton Coast.
