Atmorans are the proto-Nordic ancestor race of humans who migrated from Snow-Throat to Atmora. Nords, while they are the "purest Atmoran blood," have Nedic blood. Nords are not Atmorans by any stretch of the imagination anymore than Imperials are Nedes.

Nedes are humans who remained in Tamriel. The purest "Nedes" are the Cryodilics(remember that Imperial means anyone of Atmoran descent in Tamriel, not the race in game). Cryodilics are split into the Tsaesci Nibenese and the Nordic Clovians. The Clovians are more related to the Nords, the Nibenese are more related to the race of men from Akavir. All Imperials have some Ayleid blood as well.

Bretons are the hybrid race of Nedic, Nordic, and Aldmeri ancestors. Some have more Atmoran some have more Nedic, similar to Cyrodilics. Keep in mind that Bretons are not "half-elves" they are more Man than Mer, despite the name Manmer.

Redguards are for the most part not of the same blood as the rest of the humans in Tamriel, which explains their unique culture.
