Haerrek is a region situated beneath the expansive glacial band that stretches across the Ice Cap area. It lies approximately 300 to 500 feet under the glacier's surface, featuring numerous passages and an array of fauna and lifeforms adapted to the icy environment. The magical fauna of this subglacial realm, when consumed, provide nourishment akin to wheat and can even reduce the time required for arcane spell memorization by 20%. Both of these benefits stem from the magical emanations emanating from the marvel COA 411.
The passages and chambers that dot this area were constructed by the Azwyr Amoruk, frost giants, and Thrallrir. These three groups have inhabited Haerrek since the Dawn Era. The Thrallrir and the region's frost giants are descendants of those who served the primordials during the Creation War, while the Azwyr Amoruk came to reside here in the Horgon Era, fleeing the decline of Saer Erkjorg.
Haerrek lies situated between the surface region Ice Cap and the Underdark region Badmaer. It is technically an aboveground area, yet remains largely devoid of light due to its depth beneath the ice.
