Even so, it is no longer the Spetim Dynasty regardless of it's past. The fact that also remains is that for a combine (give or take) 100 hundred years, Uriell Septim VII's rule was remembered as a prosperous time of peace, and then for Martin's sacrifice to save Tameriil from Mehrunes Dagon cult, the Mythic Dawn, led by a High Elf, Mankar Camron. Only furthers the fact that with the last two Septim's in memory, are what filled the Imperial allegiances with pride for the Septim Dynasty.
The Mede Dynasty saved Tamriel from Umbriel. Facing off legions upon legions of undead which assaulted the very walls of the Imperial City, devastated most of Black Marsh, all the while souls were taken and used to fuel the floating city, used even in their food.
So, take your pick. Death by Daedra or No after life, but to be eaten in some twisted manner to please the stomach of a Lord.
They are of the same faction regardless, and cannot be allowed to continue to hunt down Skyrim's citizens. It also cannot be denied that the Thalmor in Skyrim are also taking resources, of materiel or magical being. That there continued presence is hurting not only Skyrim, but also the Empire and only by breaking free from Imperial rule can Skyrim better aid the Empire in long run.
If you choose to support the Empire in the civil war, you are dooming Skyrim citizens to a life of fear and for some, death. For you would allow the continued presence and operation of the Thalmor Justicars within Skyrim, and this does not offer any foreseen advantages for the Empire.
Skryim rarely remains united for long. Hence how Tiber Septim was able to take the Nords easily, due to their conflicting nature, they fight amongst themselves between clans and Jarls.
So you also have the chance of dooming Skyrim's citizens to petty violent outbreaks, skirmishes between Jarls and Clans. For the province to descend into chaos, while Cyrodiil faces three provinces of the Aldmeri Dominion. If they lose, the Aldmeri could sweep into Skyrim. The Nords fearful of magic, and having no Battlemages, stand little chance against an army of many magic users.
Fireball vs Axe dragging pelt wearers as the Nords are so politely referred as by other parts in Tamriel.
