Dagnor's Pass is named after Dagnor's Cauldron, a mountainous wasteland with a lake in the middle that contained two dungeons - Kedge Keep and The Estate of Unrest. During The Shattering, Dagnor's Cauldron and Kedge Keep were destroyed and the lake drained into the Ocean of Tears. However, some unknown magic protected the Estate of Unrest, and it now sits on a floating island above the ocean.
Dagnor's Pass is a barren trail that leads to Unrest. It is devoid of most life, but Danak Dhorentath, prophet of Cazic-Thule, has set his dreadful altar here.
