From publisher blurb:
Orbaal, a fractious kingdom in Hârn's wild north, is a land of mountains and fjords. A land where the rebellious Jarin, beaten but not broken, chafe under the rule of Ivinian viking conquerors. Around 8,000 Ivinian conquerors hold almost all of the kingdom’s fortresses and rule over 65,000 Jarin. A major rebellion erupted less than 20 years ago and considerable tension still smolders between the two cultures, encouraged by an active but disorganized Jarin resistance.
Orbaal is an exciting kingdom for your Hârn campaign. The unstable political and cultural environment provides a variety of adventure opportunities for your PCs.
The Kingdom of Orbaal module is the perfect companion to other Columbia Games publications, including keeps, castles, and adventure sites.
