TES 4: Oblivion begins with the arrival of Emperor Uriel Septim VII (voiced by Patrick Stewart), accompanied by a troupe of Blades bodyguards, at the Imperial City prison, seeking to flee from a group of assassins—later revealed to be members of the Mythic Dawn—through a secret underground exit in the city sewers. By chance, the exit is located in the cell occupied by the protagonist. The Emperor frees the player as he believes that he saw the character in his dreams, and sets off into the catacombs as the protagonist follows. At the end of the catacombs, the group is ambushed, and quickly overwhelmed by assassins, which results in the protagonist taking on the task of guarding the Emperor while the surviving bodyguards engage the enemy. While awaiting the result, Uriel entrusts the protagonist with the Amulet of Kings, a special amulet that can only be worn by those of the Septim bloodline. He orders the player to take it to a man known as Jauffre. Immediately afterwards, an assassin ambushes and kills the emperor before he is, in turn, defeated. The sole surviving guard, Baurus, questions the protagonist, and explains that Jauffre is the Grandmaster of the Blades, and can be found at Weynon Priory.
Again, a generic "save the world" story.
