- Hello there, fellow refugees!

Tahn was an Earth Kingdom refugee heading to Ba Sing Se with his family. He was a jolly man who was always happy to say hello to fellow refugees. Tahn was a caring husband with a level head. He appeared to have tried to keep an optimistic outlook on things and was always there to comfort and offer words of hope to his wife when she became discouraged.

History
After his home in the south was raided by the Rough Rhinos, he began the trek to Ba Sing Se to begin a safer life there for his family with his then-pregnant wife, Ying, and his sister. They traveled for months up the west coast.

Tahn and his family were briefly seen when Zuko was traveling alone. The exiled was starving and wanted to steal from them, but he changed his mind when he observed that Ying was pregnant.

Aang and his friends were about to leave a waterfall, when they ran into the Ba Sing Se-bound travelers. Katara invited them to travel with them, but Tahn told them that the Serpent's Pass was far too dangerous. Instead, they planned on traveling via an underground ferry system at Full Moon Bay that lead to Ba Sing Se. Aang and the others agreed to travel with them.

Back at the station, the clerk turned out to be extremely strict and ruthless. Tahn and the family showed up again, looking for Aang. Someone had stolen all their belongings, including their passports and tickets. Aang tried to get the clerk to give them replacements, but she refused, complaining that she couldn't bend the rules. With no other choice for the family, Aang gave up their tickets and offered to guide them through the Serpent's Pass.

The group reached the pass, which, seemingly against its name, was very straight, but very narrow. Much of it was barely wide enough for people to pass through single file. Ying seemed to lose hope, and Aang said that perhaps it was best that they did abandon their hope, and instead focused on the present need to cross the pass.

As the group traveled along a sheer cliff side, Fire Nation forces patrolling the water were pointed out. Suki told the group that the forces were rumored to be working on a secret project. As they continued, Tahn fell when the ground under him crumbled. Toph saved him, but the falling rocks drew the attention of the patrol ship, which launched a fireball at them. Aang leapt into action, knocking the ball back and striking the ship's engines. The group ran to the shelter of an outcropping wall of rock, leaving the ship behind to tend to its damage.



That morning, Aang's group came to a large setback: a portion of the pass was currently underwater. Katara stepped forward, parting the waters to allow them to pass. As the path got deeper, Aang helped her, forming a bubble of air for them to walk underwater safely. As it turned out, the Serpent's Pass was named (and feared) not for its shape, but for the gigantic sea serpent that swam in the surrounding waters. The serpent attacked the bubble, forcing Toph to raise the sea-floor under their feet. This stranded them in the middle of the water, with the serpent circling around. Aang attacked the serpent, telling Katara to get the others across while he distracted it. Katara created an ice bridge for the others to cross.

The group finally crossed the Serpent's Pass, just in time for Ying to go into labor. Katara, who had experience in birthing children, quickly took charge. The baby, a girl, was born with no complications, thanks to Katara. Aang, seeing the family coming together, renewed his hope, which was what the family decided to name the baby, Hope.

Tahn and his family eventually reached Ba Sing Se and they established a residence in the Lower Ring. Tahn is later seen clutching his distressed family as the Fire Nation invaded Ba Sing Se.

His and his family's fate after Ba Sing Se's liberation and the War is unknown, although it is likely that they lived peacefully.
