The ancient Dwarven temple Fjellraizad (the hollow in the roots) has stood since the Age of Heroes. The Korobokuru of later ages treated the Empyrean Temple with less and less care, eventually re-purposing it as a Waidan shrine.

In the year 158 of the 5th age, a terrible flood ravage the landscape, causing many of the local dwarves to flee their homes and head to Fjellraizad at the root of the mountain. Unfortunately, violent creatures from the mountains also sought shelter in the waterlogged shrine.
