This boomtown quickly came to be after rare and valuable metals were discovered in the nearby mines. In a very short amount of time, earthbenders from all over the Earth Kingdom came here to mine for the valuable metals. For years Tu Zin was a thriving town that flourished with commerce; however, people began to leave after the mines dried up. The villagers abandoned the town to search for new opportunities elsewhere in the Earth Kingdom, leaving behind several possessions and leaving the town to decay. It was not long before everyone was gone, leaving this place a deserted ghost town.
Tu Zin is not known to have had any major involvement in the ongoing war that had engulfed the rest of the Earth Kingdom. However, Avatar Aang arrived at this town while fleeing from Princess Azula. Sleep-deprived and exhausted, he finally faced her here and was moments away from fighting her when Prince Zuko interrupted their standoff. He too had been following the Avatar by trailing his sister. Both siblings were intent on capturing Aang for themselves and fought each other as they chased Aang through the rotting buildings.
After knocking out Zuko, Azula cornered Aang and was only stopped from her attempt to end him thanks to the timely intervention of Aang's friends. Zuko's uncle Iroh also joined the fray, and soon Aang, his friends, Zuko, and Iroh were all battling Azula. They quickly cornered her and when she saw that she was overwhelmed, she "surrendered" to the group. However, this was just a diversion and she blasted Iroh with her blue flames. The four remaining benders, Aang, Zuko, Katara, and Toph attacked Azula simultaneously with their native elements. Unfortunately, Azula blocked the attack with a fire shield and the resulting explosion set most of the ruined town ablaze allowing her escape. Zuko furiously drove away the Avatar and his friends despite their attempts to help him heal Iroh.
Afterward, Zuko cared for his wounded uncle in a ruined shack located on a hill outside of the city. This was also where Iroh continued Zuko's training, teaching him about the four nations and the redirection of lightning.
