In Skyrim I've finished the main quest but I still have the Elder Scroll. There's a funky visual effect when I try to read it but it doesn't seem to do anything. Is there any point hanging on to it now (maybe there's another special location where something happens if you read it there?) or should I just store it or sell it?
The elder scroll you gain from the main quest is now used in the Dawnguard DLC as well. If you sold it to the orc you'll have to buy it back from him for 4000 gold. You also gain two more elder scrolls. The new two can be sold to the Moth Priest for 6000 gold in the Dawnguard DLC if you sided with the Dawnguard. Alternatively you can just give him the scrolls for free (much to his astonishment).
