Whoa.... Okay. I just wondered if he seemed like Dracula being just the way he was sit in that throne, cause it looked familiar.
Anyways.. 
Nice video, AND song! <3
You should play Legacy of Kain: Soul Reaver if you haven't. Great story.
In the first game in the series, Legacy of Kain: Blood omen, Kain is a noble who is murdered and then resurrected as a vampire. Kain becomes a hero and is given a choice- The Pillars of Nosgoth, a place with great power which protects Kain's world is threatened by a great evil. Kain is sent on a quest by Ariel (the woman who is the ghost in the video) to stop the evil and save the Pillars from being destroyed. However, after Kain completes the quest he becomes so powerful that he decides to destroy the Pillars himself and become the ruler of the now ruined Nosgoth by becoming the king of vampires who then control Nosgoth.
This is the Reason why in the video, the opening of Legacy of Kain: Soul Reaver, he sits on a throne under the ruins of the Pillars.
