The Universe
The world of the Elder Scrolls is well-known for its attention to detail and realism, replete with an interconnected structure of various societies, cultures, and religions, each backed by a thorough historical basis, revealed to Elder Scrolls aficionados (who often assume the title of "loremaster") through in-game literature and deep, multi-tiered conversations. Set within the mortal realm of
Mundus, the Elder Scrolls games are invariably placed within one or more of the nine provinces of the continent of
Tamriel, these being:
Furthermore, certain titles - namely The Elder Scrolls:Battlespire and The Elder Scrolls: Oblivion - take place partially within the alternate,
Daedra-ruled,
Planes of Oblivion.
While it is known that continents other than Tamriel exist, players have not yet visited them in any official game.
The Scrolls that Fortold of Black Wings in the Cold (aka The Elder Scrolls)
The
Elder Scrolls, sometimes called the Aedric Prophecies (though the accuracy of that term is often disputed), are scrolls of unknown origin and number which simultaneously archive both past and future events. The number of the Scrolls is unknown not because of their immense quantity, but because the number itself is unknowable, as the Scrolls "do not exist in countable form". They are fragments of creation from outside time itself, and their use in divining prophecies is but a small part of their power. They simultaneously do not exist, yet always have existed.
After rumors circulated following the
Oblivion CrCIA that a Scroll (or a Kel in the
Dragon Language) was stolen from the Imperial Palace by the Thieves Guild, efforts to take inventory of the Scrolls proved fruitless as their numbers and placement seem to fluctuate for no discernible reason. The home of the Elder Scrolls within the palace has been known as the Imperial Library, the Hall of Records, and the Elder Library.
