Understone Keep

skyrim understone keepUnderstone Keep is an ancient Dwarven keep built into the mountainside, used as a palace by the Jarl of Markarth. It sits at the entrance to an excavation site aimed at unearthing Nchuand-Zel, a cavernous Dwemer castle carved deep into the mountain, containing Falmer and Dwemer machinery (traps and automatons). The excavation is headed by the mage Calcelmo, who is an expert on the Dwemer placed in charge of curating artifacts extracted from the site. The site itself and Calcelmo’s museum are accessible, but only after agreeing to kill Nimhe, a giant frostbite spider blocking the entrance to Nchuand-Zel.
