For The Legion
In the year 2E 580, the Three Banners War, commonly referred to as the Alliance War, broke out following the death of Emperor Varen Aquilarios. With the ascension of his Daedra worshipping wife, Clivia Tharn, to the position of Empress-Regent, the whole of Nirn was threatened with a Daedric Invasion.
Thus, the Daggerfall Covenant, Ebonheart Pact, and Aldmeri Dominion all declared war on the Empire of Cyrodiil. While the armies of these factions were converging opinions within the empire differed, and split.
On one hand there were the ones who decided to defend their homeland against the foreign invaders, even if they fought for a Daedra Worshipper. On the other, there were those who decided to instead side with the invaders, believing the Daedra to be the ultimate enemy.
However, based in the forests around Kvatch lies the 21st Legion, commonly dubbed by many as the Rogue Legion. The reason for this is due to the fact that, instead of choosing to submit to the Daedra or a foreign power, they instead formed their own cause, to create their own empire and carve their way to victory. Unfortunately, this declaration led to every available army bearing down on them, eager to crush the fledgling movement.
And so, the Legion is forced to resort to the use of a mysterious Ayleid portal.
A portal rumoured to have the ability to reach other worlds...
