Atmoran

The now extinct first race of man the Atmorans originally lived on the frozen continent of Atmora, where they banded into small clans. They fought in a great civil war at one point. A small group of the Atmorans migrated, and settled in northern Tamriel.

Ysgramor
The Nordic hero Ysgramor, leader of a great colonizing fleet to Tamriel, developed a runic transcription of Nordic speech based on Aldmeri principles, and was the first recorded human historian. Ysgramor's fleet landed at Hsaarik Head at the extreme northern tip of Skyrim's Broken Cape. They built the legendary city of Saarthal and lived in relative peace with the Snow Elves until they began to notice the comparatively fast growth of the Nedic people's population.

Night of Tears
The Elves drove the Men away during the Night of Tears, but Ysgramor soon returned with his Five Hundred Companions. These Five Hundred Companions settled and those who stayed in Skyrim became the Nords, with those going west breeding with Mer and becoming the Bretons and those going south becoming the Imperials.

The remaining Nords raided Elvish settlements along the coast from Skyrim and Atmora until 1E68. The last two ships from Atmora pulled into a harbor with more than half their crews dead. Atmora had become a frozen wasteland, and all who still lived there had died.
