Nchuand-Zel Excavation Site

The Nchuand-Zel Excavation Site is a location on The Elder Scrolls V: Skyrim. Located inside of Understone Keep in Markarth, it is the home to Nimhe, a giant Frostbite Spider. This excavation site also contains Alethius's Notes in Nimhe's lair, which, upon reading, begin the Lost Expedition quest.

To reach the Nchuand-Zel Excavation Site, enter Understone Keep and immediately go to the left. You will climb a small hill. Continue going straight, climb the set of four stairs, which lead to a larger flight of stairs. At the top of the second set of stairs is the entrance to the excavation site. If you do not have the key, you will have to pick an Adept-level lock. To obtain the key, speak with Calcelmo, who can be found around the arcane enchanter and the alchemy lab to your right before climbing the set of four stairs. He will task you with killing Nimhe and, presumably, present to you the key to the excavation site.
