The Gosai Mountains are a place of oldest legend. It was here that King Gabriel trained under the wise master Gosai, and where the angel Asmodeus fell down the Steps of Heaven, and where Saint Palonis vanished after the war, and many other myths.
Nowadays, though the peaks are still largely unexplored, the Mountains are home to the Viking breweries founded by Lord Torsty. From here, a daily supply chain of alcohol and rare animal furs travels down narrow mountain paths to be sold in the City and the Cult Quarter. And likewise, the mountains are never without a band of adventurers seeking to hunt some mythical beast or find the lost temples of Gosai.
The largest peak - Mount Iwaku - is capped in ice and subject to constant storms. Few who go up there ever return.
