Adrglof is an unnatural glacier of the Ugradrath mountain range. A holy site for followers of Thyrm, at its heart is a fallen general of the Creation War (1486 DE - 8777 DE). Serving on the side of the primordials, this icy champion was a Thrallrir named Beir Thonn.
Very powerful, able to manipulate the energy around him, Beir Thonn died in the Demon Spawn War (8972 GE - 9493 GE). Upon his death, in a last act of defiance, he warped the energy fields around him. The result was a rapidly forming glacier that filled the valley. It froze Beir Thonn and his demon assassins, shattered them with the rapidly forming glacier. The stuff of Fimbulwinter, ice of Adrglof is as hard as bronze and highly resistant to fire.
