Erollis is the landmass that is contained within the Frostfang Sea. It is composed of stone, ice and a small quantity of vellium. Mithaniel Marr blessed this land when he was looking for a place to settle his displaced followers after The Rending. It's oldest sentient races are coldain dwarves and a group of pale-blue-skinned orcs, the Ry'Gorr. After the coldain built the city of New Halas per the orders of Marr, other sentient races begin to move in, namely Barbarians and Frogloks.

As chronicled in the Frostfang Sea Timeline, Erollis was and still is a site of skirmishes between the coldain dwarves and the Ry'Gorr orcs. Related, New Halas is a refuge city that takes in any hard-working, well-spirited individuals and as a result there is constant pilgrimage to the city. These pilgrims are often caught in the crossfire between the warring dwarves and orcs.
Also revealed in the Frostfang Sea Timeline, Erollis has always remained frozen, even when it drifted through warmer waters. This is due to an ancient elemental being that while dormant is able to influence his surrounding habitat, keeping it in a perpetual frozen state.
