Dirrinir, the Deathly Mountain, is a towering peak of barren rock in Iobaria's Icerime Peaks. The mountain itself is carved with craggy steps that predate even the cyclopes of the Koloran Empire, which lead up to the over 20 entrances to the mountain's labyrinth-like caverns. While some legends argue that the first giants or cyclopes were spawned within the mountain, it is known that numerous powerful artifacts have been recovered from its depths, including the Diadem of Thyrv, the Crown of Mirim, the Perobov Maul, and Kridor's Shininglaive.1
