The Elder Scrolls IV: Oblivion

In the heart of Tamriel, the Imperial province of Cyrodiil, the fate of the land hangs in the balance. Emperor Uriel Septim VII's life is cut short by an assassination, but as his final act, he entrusts the Amulet of Kings to you. This ancient relic sets you on a perilous quest to find Uriel's illegitimate son, the last hope for the throne. As the boundaries between the mortal world and the realm of Oblivion begin to blur, the forces of darkness converge on Tamriel, threatening to engulf its inhabitants in eternal night. With the Empire's future hanging by a thread, the weight of the world rests on your shoulders, as you stand as the sole guardian against the gates of Oblivion.
