The Dragonborn

The Dragonborn is the main protagonist in the 5th installment of the Elder Scrolls series, The Elder Scrolls: Skyrim. The Dragonborn's goal is to slay Alduin, the self-proclaimed king of the dragons[and the Nordic god of destruction], who also strives to rule the entirety of Nirn as a tyrant.The Dragonborn is the only one who has the ability to stop Alduin, thus purging Tamriel of Alduin's evil. The Dragonborn holds great power and has superhuman abilities no other man can use. The Dragonborn also has the astonishing ability to use Thu'um, or Shouts. These Shouts are primarily used by dragons, and the Dragonborn can use them too, because he/she also has the ability to absorb the souls of dragons when they are slain.

Lore
The Dragonborn is an old Nordic legend. The First Dragonborn was Miraak, whom is also the main antagonist in the latest downloadable content for Skyrim. The Septim dynasty, founded by St. Alessia in the First Era, was known as the line of Dragonborn Emperors and Empresses because of Alessia's pact with Akatosh. The Nords of Skyrim revered the Septims, as the Dragonborn plays a major role in their mythology.
