Lorevaults are secret places for the Lorewalkers to store the dangerous artifacts. One of the vaults is located to the northern coast of Pandaria and originally contained a powerful artifact known as the Blank Scroll.
The Lorewalkers used their magic to conjure pandaren stories to protect the vaults. The stories often send a message to those who encountered them. In order to solve the puzzles and break the spells, those who are trapped within must understand the moral of the stories. The current known story mazes are: The Maze of Mad Emperor Ku, Di Chen and the Desert, and the Spiders of Te Zhuo.
Although not vaults, there are notably several small caves throughout Pandaria which contain books, scrolls, and other items which might be used by the Lorewalkers. Most often these caves are empty of people, though some have been taken over by creatures to use as shelter.
