Earth Kingdom Royal Library

The Earth Kingdom Royal Library is the center of the knowledge of all Earth Kingdom-related topics. The library is located at the city of Omashu. It contains books of bending, records, battles, spirits, locations and more. The library is heavily guarded by Omashu guards. To enter the library, one must be a master Earthbender and know a secret and unique password which is made or changed by King Bumi. Team Avatar travels to the library and sneaks by two guards conversing about the library's new password. They learn the password is Zommy Bumi and are allowed to enter. However they still have to sneak past other guards. At the library, they find a scroll containing battle records and bending moves. Another scroll has an image of the Earth Kingdom and somehow they find out that there is a hidden island where the Fire Nation forces Lian to make machines.
