Shrine of Mehrunes Dagon

The shrine is dedicated to Mehrunes Dagon, the Daedric Prince of Destruction, Change, Revolution and Ambition. The shrine door remains locked, and the site devoid of any worshipers, unless Silus' quests are done. To gain access to the interior of the shrine and to spawn the two leveled Dremora outside, the quest Pieces of the Past must be completed. None of the four Dremora respawn anymore.

Nearby locales
The Shrine is situated midway between The Lord Stone and Skyborn Altar, visible from the Lord Stone which is northeast. Near the Skyborn Altar, a word wall can be found. There is a path leading up into the mountains, just west of Hall of the Vigilant. The path has a stone marker and goes up steeply in a south westerly way and ends in a stairs up to the Shrine.

Alternate paths and cliffs
There is also another path directly south of Fort Dunstad leading in a westerly direction. This path has no markers. It winds up into the mountains, and near the peak does a hairpin turn around a giant rock plinth.

Because of the steep steps and hills around it, using Unrelenting Force on the Dremora that descend the stairs causes them to be knocked off the cliff.

Loot
There is a possibility to find Ebony Armor, though it may be a leveled occurrence. Daedra Hearts can also be looted from the Dremora. There are multiple chests with gold and enchanted equipment inside, as well as already open chests filled with Gold Ingots and Ebony Ingots. Also, all of the ingots and ingredients within the shrine respawn when the Daedra do, about 7 in-game days. The shrine can be a great source of the materials required to smith Daedric Armor.

 * Unique Weapon: Mehrunes' Razor (Only from the quest)

Bugs

 * After killing Silus, the door to the shrine remains locked, although the quest is complete. The key must be obtained from the Dremora that attack thereafter.
 * When turned into Dead Thralls, the Dremora at the shrine may go missing, randomly reappearing some time later, often hostile with a reset inventory, (keys to Mehrune's Shrine included) and attacking any unsuspecting NPCs in the vicinity.
 * Sometimes the Dremora will not respawn after a week's in-game time, but the other loot in the shrine will refresh.
