Calcelmo is a Altmer conjurer who is researching the Dwemer ruins beneath Markarth. He leads the excavation site in Understone Keep, from his workplace down the tunnel to the left of the entrance in the keep. He is writing a book on the translation of the Falmer language. Other characters seem to think of Calcelmo as a little eccentric, noting that all of his time is only spent researching the ruins. When first approached, he is very occupied with his work and almost refuses to converse.
