Ok, so I killed Alduin in Sovengarde and I went home to drop off my Elder Scroll and I couldn't. This beast weighs 20 pounds or kilos or whatever and I want it gone. Please help and thank you for your time.

The only way I've found to get rid of it is to give it to the guy in the mage's college that runs the book store. He gives you like 2000 gold in return.
