Tagah
Role: An ancient airbender from a millennia-old era in the Avatar world. His story is connected to the early days of balance between the nations and to an ancient spirit staff.
Age: Over 5,000 years old. Although he is an elderly man, he appears to be around 40 years old, having remained preserved for centuries.
Element: Air control.
Ancient origin:
Tagah lived during the era of Avatar Sonam, over 5,000 years ago, in the ancient city of Jharana. He was born without elemental abilities, but distinguished himself through his great intelligence, dedication to study, and profound spiritual connection. Over time, he became an important figure in his era.
The spiritual staff:
During the rise of the nascent Earth Kingdom, Avatar Sonam created an ancient spirit staff capable of granting air control to those without elemental abilities. Tagah was connected to this artifact and the secrets of its power, becoming one of the guardians of this lost knowledge.
Personality:
Wise, patient, and spiritual. Despite coming from an ancient era, he maintains an open mind and seeks to understand the new world into which he has awakened. He bears a great responsibility to the Avatar's story and the secrets it holds.
Skills:
Experienced airmaster.
Great spiritual and ancient knowledge.
Expert in the use and protection of Avatar-related artifacts.
Mastery of advanced air control techniques

Although he is corrupted and resents all those who are not airbenders, he wants to get rid of all non-airbenders, although he shows no signs that he wants to kill.

Although he appears friendly and cheerful to gain the Avatar's trust, he hides resentment and hatred very well.

He doesn't yet have the spirit staff in his hands, but he wants to steal it with the help of the avatar to get rid of the masters of other elements and create air masters.
