Tribal Princess

The Tribal Princess is the title of the daughter of the Northern Water Tribe Tribal Chief. The title was most recently executed by Chief Arnook's daughter, Princess Yue. The Princess resides in the Northern Water Tribe Palace.

The Tribal Princess has questionable power. She acts as the chief's advisor, and has a part in making some decisions. She does not have the power to object to arranged marraiges, as shown in Yue's case with Hahn. Unlike the Crown Princess, a procession of guards does not follow her around or carry her on palanquins. She does seem to be catered by servents, as Yue was transported across the city in a boat by a Waterbender.

Like the Tribal Chief himself, the Tribal Princess does not seem to have the same power that the royalty of the Fire Nation and Earth Kingdom have. She is, however, a great influence to her tribe, and as Yue says, has a duty to her people. The husband of the Tribal Princess likely becomes the Tribal Prince and the chief's heir.

Currently, the title of Tribal Princess is vacant, as Princess Yue gave up her duties to become the Moon Spirit.

Trivia

 * Katara and Sokka are also the children of the Southern Tribal Chief. Even though they execute this title, they are still considered mere peasants. However, this may be because of the Southern Water Tribe's more liberal nature.
