As in, Landfall=neglection to love, lead to a more specific event, like Morrowind's destruction. Landfall isn't lie rock's collision, but the sum of all that's wrong with Nirn and Dunmer.
I know about the symbolism, Ive never argued that, but if it's the sum of all thats wrong with Nirn, why just pick on Morrowind? I get the sense from the Loveletter that something bigger is/was/might'a/could'a/should'a/would'a been far more devastating...that is all...
Edit: nothing to see here, ignore the hot brunettes and make your way to the nearest exit...
