you got fucking kings, Torygg, Helseth, living gods of the Tribunal.... under an "Emperor"? who puts some garrisons around but does.... what exactly?
theres an "East Empire Trading Company"? whats that do?
it kinda seems like a holy roman empire, kinda seems like a regular roman empire. they've got knights, dukes, but a Legion...
yes i know the answer is technically "these jackoffs just made it up as they went" and don't care a lick about political theory but this is exactly the kind of excercise that makes fun speculative historiography
Doesn't the Septim bloodline have some magical powers to keep Daedra at bay? Nobles and such would want a figurehead around for practical as well as symbolic reasons. This ended in Oblivion, leading to their decline.
Come Skyrim and Imperial nobles will hire Dark Brotherhood to assassinate an Emperor they dislike.
They were in decline during the second era due to Molag Bal invading Nirn, but that was before Tiber I believe. They were prominent before the second era due to them obliterating the elves of Cyroriil and establishing the Empire in the first place.
There were technically a couple of empires. You had the Allessian empire, the Reman empire, the Septim empire, the Mede empire, and a handful of interegnum empires in between each major dynasty/era.
But ya, the dragonfire covenant is a big reason you can point to for why the empire was relatively stable. Having the head god of your pantheon literally backing your government and in the process keeping the devils out, is damned good for legitimacy.
The Septims have the power to change the very environment around Cyrodil so that it was simultaneously always boring English countryside and not the cool Italian/jungle mix the of lore claimed. This is 100% cannon
Tiber Septim channeled all the power of the Numidium to make Cyrodiil's countryside easier to render on the Xbox 360.
Tiber Septum used his super powers to make sure Bethesda didn’t have a concept designer for oblivion
