Sorry guys. I was on holidays during this week... but here we go with new chapters

"Who are you guys?"
Sokka asked with an arched eyebrow at the sight of all these people. He obviously wasn't expecting to see air nomads, but he wasn't expecting to see people here either.
Then a boy in a wheelchair walked over to where Sokka was and extended his hand, "Hi, my name is Teo, how did you get here?"
"In my balloon, of course." Sokka pointed at the hot air balloon in the center of the courtyard.
"Impossible, I was the one who invented war balloons" a middle-aged man appeared, "How did you manage to make one, kid?"
"The same way you did, I guess." Sokka quickly scanned him, at a glance he could see he was a mechanic, "I still don't know who you are."
"Oh, we... our village was destroyed years ago and we discovered this place, so we settled around here," the mechanic replied.
"This place was empty and full of interesting stuff, so we discovered gliders and made our own version of them."
"Even one adapted for Teo!" the mechanic exclaimed pointing at his son and Sokka noticed his chair, it was peculiar to say the least.
"What happened to him?" asked Sokka.
"Because of the flood that hit our village, he became paraplegic and also lost his mother" the man lowered his gaze, somewhat sad.
"I'm so sorry" Sokka understood how hard that must have been, "I hope you've found your home in this place, although I see that's the case"
"Yes, Teo feels happy and even more since he can fly with his gliding chair" the mechanic looked at his son with a smile. Sokka smiled the same.
"I won't stay long, I needed to make one last stop before reaching the North Pole" commented Sokka looking up at the sky.
Then the man handed Sokka a glider, "Well then, you are welcome..."
"Sokka, my name is Sokka" the boy smiled taking the cane, it was a glider.
"Do you want to fly with me Sokka?" Teo asked pushing his chair and Sokka nodded. He had seen Aang do this a couple of times. It would be easy.

'No, this isn't as easy as I thought!' Sokka exclaimed in his mind as the wind whipped hard in his face, 'Does Aang always do this?'
"Try not to open your mouth too much, or bugs will get in" Teo commented with a smile, since this always happened to rookies.
Sokka was going to answer, but instead he just nodded at him, so that flies wouldn't get in his mouth, he was smarter.
After a few minutes they landed, "You did pretty well Sokka, aren't you a glider?"
"I doubt it, I'm more of a water warrior than an air nomad" Sokka replied smiling, "Hey, by any chance Teo, do you know of any library in this place?"
"There's a pretty old one in the back, but it only has old scrolls" Sokka widened his eyes at that mention.
"Could you take me?" Sokka was curious.
"Okay, but I'm sure you'll get bored soon" Teo took out his wings from his chair and started flying.
Sokka followed behind him, and they circled around the castle, reaching the back.
After getting out and walking for a while, they found that room Teo mentioned, "As I told you, the room is pretty old"
"Well, if there's one thing I've learned it's that old is synonymous with wise" Sokka commented as he entered and started snooping through the scrolls.
"What exactly are you looking for?" Teo was curious, Sokka seemed too instigated.
"Airbenders were experts at blocking Chi, I want to know much more about that art" Sokka answered sincerely. And Teo nodded.
"Maybe between the two of us we can find it first" Teo offered to help but then Sokka raised his arms, victorious.
"I found it!" Sokka squealed happily. He only saw the word 'Chi' and knew it was that scroll. He confirmed it when he saw the drawings.
A human silhouette was drawn with the Chi paths and chakra bridges.
Chakra bridges were barriers that contained spiritual energy, just as a dam contains the water of a river.
If these bridges were released, the person would reach their full potential, but for that they would have to detach themselves from the earthly plane.
That is, not have any ties to this world, and that included detaching themselves from their loved ones.
