So.... Landfall was written by an ex-Bethesda employee who actually worked on the team that designed the lore for the series, but this specific-event kind of spoils the whole series, in a way. It basically states that in the end Tamriel and the rest of Nirn are destroyed (specifically somewhere around the fifth era) by the Numidium, which basically reactivates (It sort of does what Alduin did, after entering the loop it eventually ended up jumping out at a much-later time period) and starts erasing all the remaining non-men races. But since men don't exist (I believe they become extinct somewhere between the 4th and 5th era), no one can give it orders. So it basically leads to the Dragon-Break and then bam! All the races end up on the moon(the Nerarevine ended up piloting the second Numidium, which let them all escape in a ship of some sort).


But something doesn't make sense, how can it be classified as canon if it directly flows in and out of real life and the world The Elder Scrolls takes place in? He specifically breaks the fourth wall after "reading" the note. I dunno. I think there's tons wrong with Landfall...

The short answer is that MK's stuff is really weird.
