A/N Kinda changed how I wanted to write this sorry it took so long to post chapter 2 and sorry its short
Many years later the boy still remains where he was left until one day an exploration unit lead by Iroh of the fire nation would stumble onto the mass of ice high in the mountains. Iroh had been separated from the group and while trying to make his way back feel through the snow and landed in a man made cave. After getting up and brushing himself off he created a small flame to see where he was at. That's when he saw the ice in the very back of the cave. Iroh started to approach it and as he got closer he could see a shape inside it. When he finally came face to face with the ice he could see the shape was that of a small boy no older then his own nephew.
"Who would imprison a child like this." He said as he ran his hand over the ice. Something caught his eye at the base of the ice. There was a plaque placed in the snow and on it was only "Here Lay Tai Ebonheart." Iroh had already come to the decision of freeing the boy and taking him back. He started with a small flame melting the ice slowly. It took some time to melt the ice slow enough as to not send the boy into shock. The ice was fully melted and the boy was still asleep when Iroh noticed a small leather bound book with the boy. Iroh pulled a blanket out of his satchel and wrapped the boy grabbed the book and left the cave. It was not long after that he found the unit and they started making their way back. The boy slept for most of the journey only waking once and only for enough time for Iroh to feed him. As the days passed Iroh read the journal from the first page to the last page. He came to understand what happened to the boy who he was and most important that the boy was now the last Chaos Bender in the world.
Finally arriving back at the Fire Nation Iroh decides to take the boy in himself and hide the fact he is a chaos bender. Chaos benders will align with the Avatar when time of need comes and this point the fire nation was trying to find the Avatar and any who would stand with him. Iroh could not let the boy fall into his brothers hands for he knew what Ozai would do to the boy. This early in the boys life Iroh would be able to hide his water bending from him and only teach him fire bending with his nephew Zuko. The two got along well and as the years went by Zuko and Tai would become equals in combat. Tai and Azula, Zuko's sister, did not get along. They were always fighting and and could almost never be around each other. It seemed that something bothered Tai about her something not many other people saw. As time moved on Tai became stronger and stronger mastering fire bending before Zuko or Azula. Then the time came for Iroh to teach Tai what he really is. Iroh pulled Tai to a secret spot to teach him of his bloodline, little did they know Azula had followed them. Once she had seen that he could bend water she ran to tell her father. When the two finally made it back the Fire Lord himself along with his personal guard and Azula. Iroh and the Fire Lord started to argue yelling back and forth followed by the Fire Lord yelling at Tai. As the confrontation starts to come to a boil they both started fire bending The Fire Lord trying to attack Tai and Iroh defending him. More the fight went along the more Tai saw that Iroh was losing. Tai stepped up and starting fighting with Iroh but was knocked to the ground by Azula. The Fire Lord was able to throw Iroh off away from Tai. The guards took hold of Iroh to stop him interfering. Tai looked up at The Fire Lord with fear the Fire Lord attacked and there was a bright flash of light.
