Calcelmo

 is a male Altmer 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. He also is an expert on Falmer, deciphering most of their language.

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.

Quests

 * Bring a Dwarven item to Calcelmo: after the Dragonborn buys the first piece of the Dwarven Armor set, or the first Dwarven weapon, including Dwarven Bolts, a courier shows up to give the Dragonborn a Letter from Calcemo asking for one to be brought to him. Finding, stealing, looting, or crafting does not trigger the courier. When you take the item to Calcelmo in Understone Keep, you can sell it to him through dialogue. You may attempt to persuade Calcelmo to pay more. If you accidentally disenchant the item before you get the note from the courier you can still "show it" to Calcelmo and get paid for your effort. (PS3 tested) Calcemo's offering price seems based on the base price of the item, which means it is not worth selling enchanted items to him.
 * Delivery to Calcelmo: talk to Kerah. She will ask the Dragonborn to deliver a ring to Calcelmo. Subsequently, the Dragonborn can purchase this ring from Calcelmo, though there isn't anything special about it.
 * Hard Answers
 * Nimhe, the Poisoned One
 * The Book of Love
 * The Lost Expedition
 * Bring an Execution Hood to Calcelmo: During the Dark Brotherhood questline the Dragonborn will be taken to the abandoned shack, the Dragonborn will have to kill one of the prisoners in the shack. An execution hood can be taken from the corpse of a prisoner. If the hood is sold to a vendor then purchased back, the Dragonborn will receive a note from a courier saying the Calcelmo would like to buy the hood, similarly to a Dwarven weapon.
