"Very well... after I returned to the Dawnguard I set out with a vampire turncoat named Serana in order to find an Elder Scroll, an artifact of untold power. We needed two, but as luck would have it, Dromaeus had already brought one of them to the College long before that. Anyway, the vampire Serana was the daughter of a powerful vampire lord, who sought to permanently block out the sun using a Divine weapon called Auriel's Bow." AEanna said, and laid a hand on the gleaming bow strapped to her back. "The Elder Scrolls held the secret to defeating him, but to get the one we needed, we had to descend into the Soul Cairn, a repository into which Necromancers pour the souls of the dead in order to gain their unnatural powers! This is why I was gone for so long. It was.. very difficult to leave the Soul Cairn once we were inside. Living beings are not meant to go there, and they do not leave easily once inside."
