Jesse's World 5th Edition
General: Skjarheim is a large, mountain-enveloped island to the northeast of the Frostfell. It is typically considered a (large) part of the Frostfell but some sages and explorers prefer to label it on its own. Why? Who knows. Sages be eccentric, yo.
Like most of the Frostfell, Skjarheim is cold, almost continually assaulted by unseasonably harsh storms and winds, and is largely devoid of vegetative life, aside from some strange sentient molds and the scraggly scrub brush that calls most of the Frostfell home. The mountains ringing the island are barely mountains at all and are more giant glaciers.
Creatures: Though remorhaz, frost wurms, and white dragons call Skjarheim home, it’s most numerous residents are the many tribes of frost giants that dwell within palaces and fortresses of ice that were cut from the very veins of the glaciers. Rumors tell of a grand palace somewhere within Skjarheim where dwells the Winter King, a frost giant of fearsome reputation, who rides a great white dragon into battle and calls himself the Favored of Kostchtchie. Whether that is true or not, none have ever been brave enough to find out.
