Royal Gallery



The Royal Gallery is a hallway within the Fire Nation Royal Palace containing large portraits of previous Fire Lords, including those of Ozai, Azulon, Sozin, and two unnamed Fire Lords. Each portrait depicts its subject holding aloft a fireball to signify their mastery of firebending, as well as imagery which summarizes events during their rule.

History
Fire Lord Ozai spent many long hours in the Gallery when he was still a Prince, staring at the images of his forefathers, hoping they would provide him with some guidance.

When Prince Zuko received a message stating that he needed to learn the story of his great-grandfather's demise, he went to the Royal Gallery and stared at Sozin's portrait. Azula found him there and made a snide comment to her brother, before helping him out by telling him the history of Sozin.

Portrait of Sozin's grandfather


This is the official portrait of Fire Lord Sozin's unnamed grandfather.

This Fire Lord is depicted in traditional Fire Lord attire, although the robes are slightly less ornate than the robes seen during Team Avatar's lifetime.

The Fire Lord is standing amidst flowers, and located behind him is a large design resembling a flower's petals. As with all of the other Fire Lord portraits, the sun is painted directly behind the ruler's head. In this particular portrait, the sun appears to be behind the darkened shadow of the moon.

Portrait of Sozin's father


This is the official portrait of the unnamed father of Fire Lord Sozin and grandfather of Fire Lord Azulon.

The attire in this portrait is very similar to the robes of his three consecutive successors, namely Sozin, Azulon, and Ozai. Unlike the previous set of attire, these robes contain more ornate gold trimmings.

An image of what appears to be a star behind a waning moon, representing the four cardinal directions, is depicted in the Fire Lord's left hand, with a similar symbol located at his feet. The portrait also contains many clouds and portrays a red sun behind the Fire Lord's head.

Portrait of Fire Lord Sozin


The official portrait of Fire Lord Sozin depicts him as he appeared during his first confrontation with Avatar Roku. The aging ruler has hints of gray in his hair and beard.

Sozin is shown with a scroll in one hand and a ball of fire in the other. Above his head is the representation of the Great Comet, later named after him, that he used to wipe out the Air Nomads, beginning the Hundred Year War. Located at Sozin's feet are five firebending members of the Fire Nation military, signifying his military buildup. Behind his head is a bronze sun.

Portrait of Fire Lord Azulon


Fire Lord Azulon's portrait represents him as a young man. The sun behind his head has a black outline, while his attire is exactly the same as his father's, with the exception of a new gold lining on the piece of his robe that hangs from his waist.

The sun behind Azulon's head appears to be blocking out the moon. Azulon is standing on top of a turtle, an animal that lives both on land and in water, signifying his military successes over both the Earth Kingdom and the Water Tribes.

Portrait of Fire Lord Ozai


The final portrait in the hall, depicting Fire Lord Ozai, is the most ornate of all the paintings. Ozai is shown bending black fire and has multiple metal cogs and smokestacks behind him, representing the advancements in technology and industry pioneered during his rule.

A large red-and-gold design is painted behind Ozai. Like all of the previous portraits, Ozai is depicted with the sun behind his head.

Trivia

 * Since the Fire Nation is based upon Japan in terms of architecture and character, the paintings of the Fire Lords mimic the style of Japanese hanging scrolls or kakemono.
 * The design of the sun behind each Fire Lord's head is very similar to the Christian design of a halo shining behind the heads of Christ and the Apostles.
