The Nords' early experience with elves was being the victims of genocide

The lore leaves this ambiguous though. There's lore that states that the Nords attacked first, and lore that states that the Falmer attacked first. What followed was a war that in the end left the Falmer driven underground, all but wiped out.

Some lore claim that the Nords justification for this is false. History tends to be written by the victors, so I lean more towards that theory, honestly. It seems unlikely that the Nords managed to re-populate with only Ysgramor and his two sons remaining. The inbreeding would explain why they all sound so dumb, though.

and it came to "Skyrim is for Nords". which can be expected, yeah, but must not be tolerated
