"Revakheim was built inside a solitary mountain".... "south of the capital city, Bromjunaar,
now known as Labyrinthian."
— Torhal Bjorik, The Dragon Forge
Revakheim is accessed from a cave at the peak of the lone mountain, between Rorikstead and Whiterun.
The bridge is destroyed! To "cross" the bridge, collect the Clay Mask found in the living quarters and equip it
near the time wound by the bridge. You will be transported back in time when the bridge was still intact.
Hint: Try using the mask in different rooms.
