Not alone.
It was the grand central air temple. It was bigger than any of the air temples and, yes, it was floating. There were people actually flying with their gliders, and Aang confirmed that they were flying and not merely gliding. "We did it buddy," Aang said tearfully to Appa, we're finally home. They found a place to land and the people around them were all amazed.
"Welcome, young monk," approached one off the elders of the group, "I see that you are one of us. It is good to see that we are still on the face of the earth below."
"What do you mean," asked Katara as she climbed off of Appa.
"We were wipe out on the earth below, were we not?" replied the elder, "wiped out by his people." He pointed straight at a surprised Zuko. Zuko finally sighed and asked,
"How did you know?"
"You don't have air tattoos, you're too light skinned to be water tribe, and you have a fire hairpiece in your hair," Zuko looked up and touched the hairpiece. He was scared now, but the elder said, "Do not worry. If the Avatar trusts you enough to let you come with him then you can visit."
"What are you a mind reader?" Exclaimed Sokka, "How did you know he was the Avatar?"
"It was prophesied that the Avatar would come and untie with his air brethren." Aang looked around and saw all the stuff he use to do. The games, air bisons, and the laughter filled his ears again. "Please, look around and play and be merry! Let us celebrate our brother's arrival, for now he is home," announced the elder as the crowd cheered.
"Home," Aang whispered as little girls and surrounded him. Being the Avatar has it's fame perks. However Aang didn't notice Katara's soft eyes turn to green jealousy.
short I know but what the hey.
