when does oblivion take place

The story unfolds in the province of Cyrodiil, at a time when Emperor Uriel Septim VII is assassinated, leading to the Oblivion Crisis—an invasion of magical creatures called Daedra through portals known as Oblivion Gates. The player's quest centers around stopping this invasion and saving the Empire during these final days of the Third Era.
