New primary objective: Find the scroll
In order to find the second Elder Scroll, head to the academy in Winterhold. In the library, you will meet a half-orc Urag gro-Shub, who will give you the mission Discerning the Transmundane. If you have previously complete the main plot line of the basic game, you must have finished this mission and already have the Scroll. it however might have happened that you sold the Scroll to a librarian. In such case you will have to buy it back for 4 thousand gold or 2 thousand if you're the Arch-Mage. The description of Discerning the Transmundane can be found in the guide to Skyrim dedicated to the main and Daedric missions.
Once you have both scrolls, take them to the prophet at Castle Volkihar. He will give you another mission.
