He remains humble and kind, even after the entirety of the Blades all pledge their service to him, an act which would enlarge the ego of nearly anyone. He is not a skilled warrior, he knows nothing of political games, and yet he accepts his role as head of the Blades because he knows that Tamriel depends on it. Yet when he realises that Tamriel is in danger, even with no desire nor knowledge of his new role, he accepts immediately. He knows he has an imperfect past, being a worshipper of Sanguine in his youth before joining the temple to repent. The very few characters who do turn out to be any good, such as Paarthnax and the Greybeards, tend to spend their whole lives away from conflict, only interfering to nudge the player character in the right direction. Even the supposedly ‘good’ characters, like the Tribunal, gained their powers through betrayal (and one of them turns into an evil monster anyway). Murderous assassins like the Dark Brotherhood and Morag Tong are rife, as well as petty villains like Maven-Black Briar. Outside of the player characters, true heroes are few and far between. Yet much rarer than that in the Elder Scrolls universe are heroes.
The Elder Scrolls universe had an absolutely vast variety of characters living gods, demonic princes, world destroying dragons.
