The world within Mundus, after long periods of division tends to unite, after a long period of unity, tends to divide. This has been so since the first creation of Nirn. When the rule of the Ayleid's weakened, man sprung up in rebellion that engulfed all of Tamriel, aided by the inspiration of the 'slave queen' Alessia.
Finally mer and man warred with one another until Skyrim joined with men, combining to make an unstoppable force that finally destroyed the Ayleid Empire, leading to a unified kingdom of man. But when the Alessian Empire had fulfilled its final destiny it was also lost, leading to more wars and great battles that where fought across Tamriel until again another achieved mastery.
The armies of Reman I of Cyrodiil and the converted allies of the Nibenay Valley army then finally destroyed the Tsaesci of Akavir at Pale Pass of Skyrim, leading to the birth of a second empire of man. The rise of the fortunes of the second empire of man began truly when Talos the supreme emperor and 'god-king' of the nine divines destroyed the allied Nord and Breton armies at Sancre Tor.
The battles of the first true emperor known in Cyrodiilic as Tiber Septim only ended when little is not under the banner of the new empire, using the great 'Numidium' he manages to conquer both mer and man so that no great force of Tamriel is left to resist him.
The magnificent heritage of the Septim's was present through the whole of the new third era of the empire's ascendancy, with only fleeting wars and conflicts annoying the great line of succession until the war of the Red Diamond. But then Cephorus became emperor after settling the civil war, which would be the beginning of a new Septim dynasty that would rule until the Avatar of Akatosh, Martin Septim would perish leaving the great dynasty gone.
Without an emperor sitting on the throne the empire was doomed to weakness, as usurper's and kings warred and wrangled to either seal imperial rule or secede from it, it soon became that the province's of eastern Tamriel would fall to a revitalised Argonian rebellion, while the Aldmeri from the isles of summerset would rise up to the challenge the empire for mastery.
Finally the empire would find it's back broken as it fought within a great war between its few remaining provinces and the Aldmeri dominion, lasting many years the war would finally end with the empire on its knees. The signing of the white-gold concordat would allow the Thalmor free reign to find and purge all Talos worship from the held lands of the empire, along with the expulsion of Hammerfell from the empire and the dissolution of the once mighty organisation the blades.
This story starts at the concluding stages of the civil war wrought from the peace treaty between the empire and the dominion, and will highlight the actions of the Dragonborn and the part he plays in the settling of the conflict.
It will settle how the slayer of Alduin set his sights on the mortal matters of the Tamrelic plains, and how he would go on to alter the history of those same lands.
