Irkngthand is an ancient Dwemer Ruin in The Elder Scrolls V: Skyrim. It is located west of Windhelm and south of Yorgrim Overlook, and is the location of the Thieves Guild quest Blindsighted. The Dragonborn cannot gain entry to the ruin before starting this quest (See Dungeon Lock Outs). Approaching northeast from Shearpoint allows entrance by descending from the mountains, and, if carried out correctly, can lead the Dragonborn immediately to the Bandit Chief, avoiding the other enemies.
