Marius has little trust in outsiders, and feels the Leyawiin is, and has, stood on its own. He goes as far as saying that the Elder Council doesn't care for the safety of the empire, and leaves the provinces to fend for themselves.
Marius funded the knightly order of the Knights of the White Stallion as a way to reward and honor free adventurers who perform noteworthy services for County Leyawiin.
During the Oblivion Crisis, he makes it clear that he has little hope of help coming from the outside, and that it will be up to Leyawiin to see to its own survival. If the Oblivion Gate outside his city is closed, he will be willing to send troops to Bruma.
- "Leyawiin is beset by enemies. The Empire does nothing to help us. Even before this crisis, I did not have enough men to patrol my borders. Now, daedra are pouring out of an Oblivion Gate on our very doorstep!"
