The O'oen Ice Sheet (pronounced aw-AW-en) is a large ice sheet that covers much of the southern Stormlands. Over a mile thick in many places, this immense ice sheet envelops the land up to the Ubaalu Mountains and the Barricades. To the south, it merges into the sea ice that covers the Ishkre Ocean.
Despite the harsh and almost featureless surface of the ice sheet, some people and animals alike manage to live on top, or within, the O'oen. Some tribes of the Uulam, though they mostly reside on its margins, maintain nomadic lifestyles on the ice, while others carve villages into the glacier itself. They feed themselves largely on seals and other oceanic creatures while fending off hostile predators in search of the same prey.
In the west the O'oen Ice Sheet once covered the glacier-carved fjords south of the Ubaalu Mountains, but in recent centuries it has melted and retreated, as it does cyclically over many millennia.
