By taking a platter and printing with it against the first half of the third entrance of the right side and dropping a "Do Not Delete" chest to preventing your Dovahkiin from falling, it's possible to find four chest. They are the, each one, the inventory of one of the master trainers that reside there. They contain gold, all spells (less Master-Level until the Rituals), Scrolls, Robes, some have Staffs and several Soul Gems.
If you don't mind clarifying a bit, or directing us to a video or better description, i'm sure a lot of people wold like to know exactly how to get to these chests. I for one hate to have to work for my gold just to give it all to the master instructors.
