Cyvus Vail was one of the most powerful beings in Los Angeles, with metaphorical tendrils extending throughout the city, obtaining and ensuring his power thanks to his vast wealth, his magical power and his membership of the Circle of the Black Thorn.
After Angel agreed to take over the Los Angeles branch of Wolfram & Hart in exchange for a new life and memories for Connor, Vail was the leader of the elite team of powerful sorcerers hired by the firm to reshape reality and alter the memories of those involved in Connor's life. Afterwards, Vail kept an Orlon Window, a magical artifact that allowed him to observe reality as it was before the alteration.
In the following months, Vail managed to obtain the Resikhian Urn in which the demon Sahjhan, had been trapped by Justine Cooper. Sahjhan was an old enemy of Vail, and had tried to kill him many times, for which Vial sought to have the prophecy of the Nyazian Scrolls (The one sired by the vampire with a soul shall grow to manhood and slay Sahjhan) fulfilled.
