The Elder Scrolls V: Skyrim - Dawnguard

Dawnguard is the first official add-on DLC for The Elder Scrolls V: Skyrim. It centers on a prophecy written in the Elder Scrolls, in which a group of vampires block out the sun for all eternity and rule all of Tamriel. Led by the Vampire Lord Harkon, a group of vampires are now attempting to bring this prophecy to fruition. The player has the option of either joining the vampires cause, or to join the Dawnstar, a group of vampire hunters attempting to stop the prophecy coming to fruition. In addition to the story, Dawnguard brings new shouts, enemies, weapons, armor, side quests, perk trees and legendary dragons.
