The Tower Stone (Skyrim)

Description
The Tower Stone enables the Dragonborn the ability to automatically open expert or lower level locks once a day.

Location
The Stone can be found between Winterhold Hold and Dawnstar, on a mountain, directly west of the The College of Winterhold. Immediately surrounding the Guardian stone are several birds nests on small stunted trees, which may each contain a random bird egg. There are two Quicksilver Ore Veins as you approach the Stone.
