Nchuand-Zel Excavation Site

Description
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 begins the Lost Expedition quest.

To reach the Nchuand-Zel Excavation Site, enter Understone Keep and immediately go to the left. Climb a small hill and 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. The adept-locked door can be picked if the key is not in the player's possession. To obtain the key, speak with Calcelmo, who can be found around the arcane enchanter and alchemy lab to the left as you enter Understone Keep. He will task the player with killing Nimhe. If the player accepts, Calcelmo will give them the key to the excavation site.

As soon as you enter the Nchuand-Zel Excavation Site, run up the first set of stairs, at the end of the hall you come to an open room that resembles a mine. the first Iron Ore is on thr right hand side just as you come down the walkway. the 2nd Iron ore is at the end of the walkway, go up a seperate walkway to your left and the vein will be beside 3 barrels. the last one is on the wall to the right just before you enter another open room (before you cut the first spider web).

When Nimhe has been killed, the player gains access to the Dwemer Museum.
