Calcelmo

 is a character in The Elder Scrolls V: Skyrim. He can be found in Understone Keep where his nephew, Aicantar, helps Calcelmo in the laboratory. He owns the Dwemer Museum and has been excavating Nchuand-Zel. As a scholar of Dwemer history and culture, he has written several books about them, including Dwarves, v1, Dwarves, v2, and Dwarves, v3.

Interactions
Calcelmo gives the keys to both the museum and dig site if the Dragonborn defeats Nimhe, a large Frostbite Spider that inhibits the progress of the excavation.

Kerah has the Dragonborn deliver a ring to Calcelmo. Subsequently, the Dragonborn can purchase this ring from Calcelmo, though there isn't anything special about it.

After the Dragonborn buys the first piece of the Dwarven armor set, or their first Dwarven weapon, a courier shows up to give the Dragonborn a note from Calcelmo asking for one to be brought to him. Finding, stealing or looting does not trigger the courier.
