Bringing this thread back to its original topic...

Alduin's Wall was created by the Dragonguard to record the history of the dragons, as well as the Prophecy of the Dragonborn. Given that this Prophecy is attributed to an Elder Scroll, it would be impossible to stop the events within it, even if one tried. The Elder Scrolls are contradictions unto themselves, existing both in time and out of it. Even if one had the foresight to dream of such events and decipher the cryptic Prophecy, whatever they tried to do would ultimately fail.

On Bethesda's part, the Prophecy tied in every other game to one whose storyline and time were completely unrelated to the previous ones.
