Despite the Fire Sages being forced under the rule of the Fire Lord, they still had significant religious power, which included ownership of the temple. Prince Zuko visited the temple to learn about the demise of his great grandfather, Fire Lord Sozin, and how it would help him realize his own destiny. He sneaked into the temple at night and followed a Fire Sage into the Dragonbone Catacombs. While in the chambers, he found and read the final testament of Fire Lord Sozin and, in doing so, learned about the demise of his other great grandfather, Avatar Roku.
