Niurin Scaa
From Mistipedia
Niurin Scaa ("Shadow Nether") was the kingdom of the Arak hidden far beneath the surface of the land of Arak. It is unclear whether this was it proper name or one affixed to it by the surface dwelling Arakians. In 740 BC as part of the Great Upheaval, Niurin Scaa and the Aark were dragged to the southwest by Gwydion the Sorcerer-Fiend. The land of Arak ceased to be and the Land of the Mists tore open beyond Tepest. The Shadow Rift, sealed by roiling black mist, was the new land and kingdom of the Arak.
