Our Tarnished protagonist goes completely un-named for the entire movie. At some point, he makes some troll allies, and said trolls wind up becoming disillusioned with the Golden Order. Led by a Carian troll knight, they depart overseas in search of enlightenment instead of coming to the protagonist'd aid.
The protagonist prevails nonetheless, taking control of the Fell Flame to do so. The end of the movie has him sit upon the throne, a flame cupped in his hand. An ally finally addresses him by name: "Lord Vendrick"
