Chronicles of Skythia
A chain of massive mountains stretching thousands of feet into the air, few have ever been climbed or fully scouted. There is only one known pass through the mountains, blocked throughly by the mountain fortress of Winterhaven.
The massive glaciers atop the peaks ensure the region is fairly cold year round, snowstorms in July happen with depressing regularity. Volcanic activity is also fairly high especially in the northern reaches and hotsprings are not unheard of. Outside of Winterhaven the region lacks much in the way of a civilized populace, but in the summer months a fair number of farms can be found at lower elevations, the rich volcanic soil ensures a bountiful harvest that attracts hardier settlers.
