Hrodulf's House is on Solstheim, southeast of Raven Rock. At the end of a secret passage (which can be found by entering the trap door to the right of the wooden chest, then going behind a bookcase) is a small Dwemer Ruin where Hrodulf's lover Bjornolfr lies dead on the floor with a Bloodstained Letter, some scattered gold coins and a Nordic dagger. His cause of death appears to come from the Reavers inhabiting the place.
