Skyrim: Tyranny of the Sun ( The Dragonborn Saga: Book 2)

"Among the night's children, a dread lord will rise. In an age of strife, when dragons return to the realm of men, darkness will mingle with light and the night and day will be as one."

Sequel to the ELDER SCROLLS: THE LAST DRAGONBORN, an ancient prophecy denotes a ritual that requires a Daughter of Coldharbour as a sacrifice and the bow of an ancient God to permanently plunge the world into eternal darkness. After defeating the Blood Knights led by the Vampire General Baklaf, Roggnavar finds himself in the company of such Daughter of Coldharbour, Serana Volkihar. With Ocellina captured and Egil on the run with Artorius and a clan of Dunmer refugees, Roggnavar has no choice but to face the legion of Clan Volkihar alone.
