This ancient structure is located within the Sky Haven Temple, located in the mountains of Skyrim. Alduin's Wall not only chronicles several key events in the history of Tamriel, but prophesizes two of the most important: the return of the World Eater, Alduin, and the Dragonborn who will rise to challenge the mighty dragon.
The leftmost and center portions of the Wall depict the rise and expel of Alduin at the hands of a mysterious band of individuals. The rightmost portion heralds the beginning of Tamriel's Fourth Era, which will be marked by civil unrest with the murder of the high king of Skyrim, not to mention the return of Alduin! Fortunately, hope may remain yet in the Dragonborn who stands fast against the World Eater.
Alduin's Wall also references prior titles in the Elder Scrolls series:
The Elder Scrolls: Arena
The Staff of Chaos which Imperial Battlemage Jagar Tharn used to imprison the late Uriel Septim VII in the realm of Oblivion.
The Elder Scrolls II: Daggerfall
The reawakening of the giant brass golem Numidium, one of the possible outcomes from the second game in the series, is clearly shown on the Wall as having come to pass.
The Elder Scrolls III: Morrowind
The Elder Scrolls IV: Oblivion
The Gates of Oblivion are highlighted on the Wall, illustrating the events of the fourth title which ultimately lead to the end of Tamriel's third era with the fall of the Septim dynasty. This wold also lead to the reawakening of Alduin.
