"Sometime around the rise of the First Empire of the Nords in Skyrim, the Velothi civilization broke down into a relatively primitive collection of clans and tribal warfare. Because of the slave revolt, many Strongholds went into opposition to hide and protect Vvardenfell's borders from the Early Nord Skirmish squads. The so-called Dunmer Strongholds of Morrowind were most likely built at this time, for defense against Nordic raiders and other Chimer too, who did not seek exile with the rest at the time of exodus. Such disunity allowed Skyrim to conquer Morrowind. The Nords ruled Morrowind, now called Resdayn, under the reign of semi-corrupt Nord Tyrants for many years, until fighting of their own (the War of Succession) allowed the Chimer and Dwemer to form an alliance against the vulnerable and rebellious Nords, and oust the occupiers."
