Elder Scroll (Dragon)

The Elder Scroll is a quest item located in, where it is central to the main quest. It is later required in as part of its main quest.

Craftsmanship
The scroll itself is housed within a gold cylindrical casing, believed to be Aedric in origin. The decorative casing is adorned with precious gems and intricate runic carvings.

Elder Knowledge
Paarthurnax sends the Dragonborn to obtain the scroll. It is eventually found in the Tower of Mzark in the ancient dwarven city, Blackreach.

Alduin's Bane
Once the Elder Scroll has been obtained, it needs to be read at the time wound atop the Throat of the World in order to learn Dragonrend. When activated, the Dragonborn will open the scroll and a blinding light will engulf their vision.

Upon completion of "Alduin's Bane", it can be sold to Urag gro-Shub at the College of Winterhold for 2,000.

Scroll Scouting
If the scroll was sold to Urag gro-Shub, the Dragonborn must buy the scroll back for 4,000, if persuaded or the player is Arch-Mage it can be bought for 2,000.

Unseen Visions
The Dragonborn is required to read the Elder Scroll at Ancestor Glade in order to locate Auriel's Bow.

Bugs

 * Obtaining the Elder Scroll before having to find it before the quest Elder Knowledge breaks the main storyline. One can obtain The Elder Scroll by console commands. Unknown if it interferes with the quest line. Still better than not be able to complete at all. Also reloading an old save is possible.
 * Trying to read the Elder Scroll while in a chest menu won't have any effect until the chest menu is exited - however when the scroll is opened normally, the screen may go black.
 * If is completed, a bug can be used to obtain an infinite number of the "Dragon" Elder Scroll, if the Scroll was sold to Urag gro-Shub before installing Dawnguard. Simply uninstall then re-install Dawnguard. The "Dragon" Scroll will be in the Dragonborn's inventory, but can be bought back from Urag during the Scroll Scouting quest, which will cause the Dragonborn to have two identical "Dragon" Scrolls. This can be repeated as many times as wished.
 * When you sell it to Urag Gro-Shub, the Elder Scroll is removed, the 2000 gold is added, but you don't lose the 20 weight of the scroll. This is because quest items have a weight of zero regardless of the weight listed in their item description.
