Final Descent

Background
I've stumbled across Crescius Caerellius inside of Raven Rock Mine. He's convinced that the remains of his great-grandfather, Gratian Caerellius, are at the bottom of the mine and that the East Empire Company has falsely designated his ancestor's death as an accident. He's tasked me with exploring the mine on his behalf to locate the remains, and perhaps discovering what killed Gratioan Caerellius.
