The Elder Scrolls IV: Oblivion takes place in the fantasy realm of Cyrodil. The capital region of the game's main continent of Tamriel is a picturesque landscape filled with vast forests and rolling hills. Players should be wary when exploring this beautiful open world, though. The game is full of several powerful enemies looking to fight the player. Add to this the fact that the region is currently under threat from an invasion from the hellish realm of Oblivion, and players will find themselves facing off against some truly powerful enemies.
