10 Speak to Serana
Dexion's reading of the Elder Scroll has given rise to more questions than answers. The Moth Priest saw a vision of a weapon called Auriel's Bow, but Serana and I need to locate two more Elder Scrolls in order to unravel the rest of the prophecy.
20 Explore Castle Volkihar's Courtyard
Serana has indicated her desire to locate her estranged mother, Valerica, who had fled Castle Volkihar with one of the Elder Scrolls. She believes that Valerica may have left a clue to her whereabouts somewhere in the courtyard of the castle. In order to avoid detection by Harkon, we've decided to utilize a hidden entrance on the back side of the island.

According to Valerica's notes found there, she has likely fled Tamriel and entered the Soul Cairn, a dimensional plane of Oblivion. In order to pursue her into the Soul Cairn, Serana and I need to recreate the experiment that opens the portal to this strange place.

90 Speak to Serana
Serana and I are trying to locate her mother, Valerica who may have one of the Elder Scrolls. In Valercia's laboratory, we've recreated an experiment she performed and opened a portal to the Soul Cairn, a plane of Oblivion. Serana believes strongly that her mother is inside this strange place and has indicated we should step through.
100 Become a vampire
When attempting to step through the portal to the Soul Cairn, a hidden force that seems to be draining my life energy is preventing me from entering. I have two choices if I wish to enter the Soul Cairn. I can allow Serana to change me into a vampire, thereby "killing" me in effect. Alternatively, I can allow her to partially soul trap me which could potentially weaken me while I roam the Soul Cairn.
