Emperor's Tower

The Emperors Tower is perhaps the greatest undiscovered mystery in the Skyrim game. Upon entering it in Solitude the player may steal some expensive goods, as there are relativly few gaurds. If one journeys to the deepest level of the tower however and enter the trap door under the stairs you will emerge in the Solitude catacombs. At the lowest reach of this catacomb lies the hammer Mjolnir which grants the Dragonborn an audience with Talos and the gift of Godhood should you accept it. Note you must have complete the main quest to acess the catacombs.

Do not accept: Talos shall reward you with a perment blessing which allows your shouts to recharge at 50% the normal speed (can be combined with the Talos Shrine blessing as well as the amulet of Talos), and the player may wield Mjolnir which does 100 damage in addition to 50 shock damage.

Accept: The player ascends to Godhood via the tower, and catches a glimpse of the future end of the 4th era, and the fall of the Empire of Tamriel to unknown forces. This effectivly ends the game and deletes all previous saves of the game so be sure your OK starting a new game. Neither can you take the Mjolnir and "end" the game.
