The Midden Dark contains a ritual chamber with a large black metal gauntlet on a pedestal. The symbol of Oblivion is emblazened on the palm of the gauntlet. The Midden Incident Report can be found on the table here, along with the Investigator's Key. Following the clues in the report, the player can find the needed rings in the Arcanaeum, in a master-locked chest. The lock can be picked, or simply opened with the key. Returning the rings to the gauntlet will activate it, and the gauntlet will clench into a fist. Shortly afterwards the dremora Velehk Sain will be summoned.

There is a tunnel leading to an exit to Skyrim below the room with the bridge. Once through the exit, the player can reenter the dungeon or jump down a small cliff to a cave below. The cave exits near the shoreline underneath the college. It is possible to enter the Midden Dark through this cave with a combination of sprinting, jumping and persistence. This is useful for characters wishing to access this area and the Atronach Forge without having to enroll with the College.
