Now I bet you couldn't say that again while wearing a waterface.
The Men that the Ayleids enslaved were decendants from the Night of Tears, in which the Elves took captives, and the Bretons were decended from those who settled in the area now known as High Rock, but then were taken as slaves by the Elves (whom then interbred with the Nedes).
And if men had been indigenous to the area now known as Cyrodiil, then why didn't Topal mention them?
Seriously? A few captives spawned an entire patchwork of tribes, with their own traits, customs and languages? (I won't list the ones whose names we know.) The dusky Imperials descended from the pale Nords? The Colovians have more Nordic blood than the Nibenese whose other ancestry is... what? The elitist, racialist elves took two dozen love slaves and had their entire population join in the fun? So all humans come from the Nords, except for the inconvenient of exceptions of the Kothri and the Ra'gada, who don't? But sources insist we're all snowmen anyway. Funny how they are so-often contemporary with Tiber Septim, who politically kowtowed to Skyrim and its supremacist self-image of the fatherland of all mankind. General Talos took a Nordic name, lied about his birth in Atmora and invented an entire creation story for himself, becoming Ysmir.
So Queen Alessia was, in fact, the daughter of bloodthirsty invaders and a usurper to the throne of White Gold Tower? So Nordic slaves submitted to the worship of Auriel, the elven demon?
Really, the Out-of-Atmora myth is as inaccurate and heavy-handed as the RL terms caucasoid, negroid, and mongoloid. Atmoran, Kothri, and Yokudan? Not likely.
'Nede' is a term that is endlessly confused with Nord (I don't deny the bewildering alliteration) or shoehorned to refer to all pre-Ysgramor Nords, and now used to refer to all non-Atmoran peoples. When a scholar bothers to actually translate period texts, we see it referring to just another group inhabiting Cyrod, distinct from the few slaves the Ayleids did indeed import from borderlands near Falkreath. The origin of the majority of our knowledge of the Alessian Revolution seems a better place to turn to than an Altmeri campfire tale. The Elder Scrolls reveal that all life is indigenous to Tamriel; they don't claim that it started in the Rumare. The Nords are merely the people who forsook Tamriel for other lands. Their own legends claim that they were born on High Hrothgar when Kyne breathed upon the snow. Surely it is impossible that every last one of them immediately departed for the north? As history, Out of Atmora is at once cobbled together and entirely too neat. As a legend of Nordic superiority and a ploy to sway the opinion of a much-needed Northern ally, it is effective.
