But one day, the elves wanted to conquer the human world using magic, and in response, the Emperor of Tamriel decides to make the magic, Tamriel and the elves disappear, on another world, called Nirn. But after millennia, the elves still want to conquer Tamriel, and the world. And that is why, 4500 years later, Tamriel is re-summoned to Earth, in order to destroy the elves once and for all.
