"Speak to Crescius Caerellius" is an objective in the side quest "The Final Descent" in Elder Scrolls V: Skyrim - Dragonborn.
Walkthrough[edit]
Head into the Raven Rock Mine, and find Crescius Caerellius within its walls. He is just down the the hallway in the first room. He is talking with his wife, Aphia Velothi, who is trying to convince him to leave.
Crescius does not want to let things go here. He explains that his grandfather was an explorer and that he had died in these mines. Crescius suspects it was not the mine, but something within it that killed his great grandfather. He will give you the letter that his ancestor sent to the East Empire Company and a key.
