Frostland

On the surface of the Abyssal Maw, at the point farthest from Deepholm, there is a mile-wide shelf of solid ice known as the Frostland. Like an immense iceberg, the Frostland extends far underneath the surface, almost to the ocean floor. Smaller chunks of ice break free occasionally and drift across the seas, slowly melting as they come nearer to Deepholm. Some of these bergs are occupied by ice elemental conglomerates or other creatures.

Ruler
It is likely that Ahune  rules Frostland.

Lokholar the Ice Lord may also hold some standing.
