Skyrim:Gratian's Letter

Gratian,

I would appreciate if you could help us with a situation we've encountered in Raven Rock. It seems that the miners there have stumbled across some sort of ruins under the surface near shaft three, and we need your expertise to take a look. I could send someone else if you're busy, but I figured you'd want to go since I seem to recall that you're originally from Solstheim. Let us know if you make any progress.
