It's cover version main theme song of Skyrim - "The Dragonborn Comes".
Our Hero, our Hero, claims a warrior's heart I tell you, I tell you, the Dragonborn comes With a Voice wielding power of the ancient Nord art Believe, believe, the Dragonborn comes
It's an end to the evil of all Skyrim's foes Beware, beware, the Dragonborn comes For the darkness has passed and the legend yet grows You'll know, you'll know, the Dragonborn's come
