Threads of Invasion
North of Khorvaire, beyond the icy coldness of the Bitter Sea, the barren Frostfell covers the top of the world. This land of perpetual winter is locked in ice and snow. Sometimes, when winter gets the upper hand, storms blow out of the Frostfell and temporarily turn other regions into semblances of this frozen waste. The dwarves believe they originated in this frozen land, and legends of strange monsters, unrestrained demons, and hordes of undead are featured in tales of the Frostfell. The only known expedition to reach the ice plains and snow-covered peaks and return to tell the tale was led by Lord Boroman ir’Dayne of the Wayfinder Foundation. More often, the Frostfell sends bitterly cold winds, snowstorms, and great icebergs to punish the southern lands.
