Royal servants

Over 100 servants work in the royal palace and tend to the Royal Family's every need. To become a royal servant is the honor of a lifetime for the servants and their families. In "Nightmares And Daydreams", the servants are seen helping Zuko dress and offering him luxuries like fresh fruit, a massage and a hot towel. The Servants are also responsible for carrying the Royal Family's Palanquin. The entire staff of servants were banished by Azula when she became paranoid and delusional. It is unknown what happened to them after this, but it is possible they were readmitted into service by Fire Lord Zuko

Azula's Servants
Azula has a special staff of all-female servants that have tended to her since she was a baby. They wash and brush Azula's hair, manicure her nails, wash her feet, and cook nutritious meals for her. They are first seen in "Nightmares And Daydreams", giving Azula a royal hair combing. In "Sozin's Comet, Part 3: Into The Inferno", Azula grows paranoid and banishes one of her servants when she finds a pit in her cherry. She later banishes the rest of her servants and the entire palace staff. It is unknown what happened to them after the war, but it is possible they returned to work in the palace under Zuko.
