Narrative
The next morning. Master Pakku is on the deck of the ship with several other men from the Northern Water Tribe. He reaches into a bag and pulls out a triangle-shaped amulet.
In a serious and ceremonial manner, he walks forward, "Katara, I want you to have this." He says, showing that it is a triangle with a wave-shaped pattern of blue color with a crescent moon on the top. "This amulet contains water from the Spirit Oasis." Master Pakku as he hands the amulet to Katara, who is standing in front of Appa and next to Aang. "The water has unique properties. Don't lose it." He says, as his face softens.
Katara bows respectfully, "Thank you, Master Pakku." She embraces him and then walks off to hug Yanna, they hug swaying side to side, with smiles and tears streaming down their faces. Aang steps forward and Master Pakku produces an intricately-decorated brown box.
"Aang, these scrolls will help you master waterbending, but remember they're no substitute for a real master." Master Pakku said smirking.
Aang looks up at Katara, who is on top of Appa, and then moves to give Yanna a big hug too, she tells him it was a pleasure meeting him, and it will not be the last time they see each other again.
"Sokka." Master Pakku says, Sokka looks at him proudly and expectantly, "Take care, son." He says, slapping his shoulder. Yanna cackles bending over trying to hold in her laugh, as Katara and Aang try to do the same. Pakku pats Sokka's arm, giving him nothing. Sokka's expression becomes very dejected and embarrassed.
He walked towards Yanna who had a sad smile on her face and she wrapped her arms around his neck as they held on tight to each other. They pulled away and shyly blushed.
"So I guess this is goodbye. We just found each other again." Sokka said sadly.
Yanna frowned then chuckled, "Sokka you are so dramatic, this isn't the last time I'll see you, I still have a duty to fill out." She said, nudging him then looked at Aang and Katara, as they smiled and told Sokka to hurry up.
Sokka nodded and smiled before walking towards Appa but stopped, and quickly grabbed Yanna's hand pulling her close to him. He cupped her cheeks and passionately kissed her lips. It took Yanna by surprise but she slowly wrapped her arms around his neck deepening the kiss.
He pulled away, grabbing her hand, slowly dropping it, before turning around getting on Appa. Both of them a blushing mess.
"Fly straight to the Earth Kingdom base to the east of here. General Fong will provide you with an escort to Omashu. There you'll be safe to begin your earthbending training with King Bumi." Pakku said, smiling. Yanna waved at them softly smiling.
"Appa, yip yip!" Aang yelled, as they took off in the sky.
Pakku turned to Yanna and smirked, "it would seem our Moon Warrior has taken a suitor." He joked. Yanna playfully rolled her eyes and shoved him out her way, making him chuckle.
-Time Skip-
"Maybe you can avoid me, but she can't." General Fong said,smirking.
The Earthbenders use their discs to create a v-shaped wall, making sure that the only means of escape is by General Fong. Katara throws her stream of water at Fong, but he raises a patch of dirt, creating a patch of mud. He takes up a fighting stance. Katara, who spins around and begins to sink into the ground. She is up to her knees in dirt. She struggles to escape but doesn't budge.
"Aaahhh!" Katara yells and grunts, straining, "I can't move!" She said, hyperventilating.
"Don't hurt her!" Aang yelled. He leaps down from the staircase and shoots a stream of air at Fong. Fong, who looks surprised, but quickly raises a wall of earth to protect himself. He lowers the wall, the turns back to Katara, who sinks deeper into the ground.
Katara sinking deeper, "Aaahhh!" She shrieked I'm fear.
Sokka, who rides out from behind one of the discs on his birdlike creature. He charges toward Fong.
"Katara! No!" Sokka yelled, as he watched Katara sink even deeper. Fong sinks the bird creature's legs into the dirt and Sokka gets tossed from his ostrich, landing in the hole of one of the discs. "Waaaahhh! Oof!" Sokka grunts.
Aang runs to to Fong, grabbing his arm. "Stop this! You have to let her go." He pleads with tears in his eyes.
Fong looks down at Aang angrily, "You could save her if you were in the Avatar state." He says, glaring at Aang. Aang became frustrated and desperate. Tears begin to streaming down his face.
"I'm trying... I'm trying! PLEASE STOP, LET HER GO!" He said desperately.
Fong clenches his fist and Katara disappears totally into the ground. Aang dives for her, just barely missing her hands. The arrow mark on his head begins to glow, and he turns around, revealing that the Avatar State has been activated. He glares angrily at Fong as he rises.
Fong, who lifts his fist into the air in victory. "It worked. It worked!" He yelled proudly.
A strong blast of wind hits Fong, and he shields himself with his arms. Aang, who is standing in front of him, wind billowing around him. Back to Fong, who smiles, but the grin quickly fades as he becomes terrified. Aang, who launches a karate chop-like attack towards Fong and the soldiers. Fong, who goes flying backward. He lands at the base of the tower. Aang lifts himself up in a vortex of dirt.
Aang, hovering, his body suddenly glows blue, a surprised expression on his face. This blue spirit form leaves his glowing body and rises into the sky. overlooking the wrecked base. Roku and Aang fly by quickly on Roku's dragon.
"It's time you learned." He told Aang.
The dragon flies off into golden clouds, there are figures standing on them. The dragon flies by, as Aang looked at them confused.
"The Avatar state is a defense mechanism, designed to empower you with the skills and knowledge of all the past Avatars." Roku told him. They see a female Avatar in a green robe and mask, holding fans. Her eyes glow briefly and she takes up a fighting stance. They see two huge statues of mole-like creatures, as she lifts them into the air and fly toward the ocean.
"The glow is the combination of all your past lives, focusing their energy through your body." Roku told him. They see a male Avatar on the end of a ship. He's wearing a blue coat and a white hat, presumably made of animal skin. His eyes glow as well, he moves his hands back making a huge tidal wave.
They see another female Avatar, whose eyes glow. She shoves her hands forward, strong winds blow the yellow grass and trees in the distance. "In the avatar state you are at your most powerful." they saw another male Avatar in red armor. He lifts his arms and four volcanoes erupt in the background.
They saw two female fire benders riding on black and red dragons, above a palace with volcanoes erupting in the back. They then flew past the artic ocean seeing a girl rise out of the ice filled water on top of a sea serpent, as a huge wave rised behind them. They flew past a air temple as a girl sat on top of a white Phoenix, it flapped its wings moving the air fast past them. Then finally they saw a girl in green standing on top of a mountain, earth bending a avalanche with bagermoles standing behind her.
"But but you are also at your most vulnerable." Roku said, sternly. "What do you mean?" Aang asked. The Avatars and protectors shown earlier can be seen on the clouds in the background. Roku and the Avatars suddenly vanish. They appear in a single-file line, their eyes glowing.
"If you are killed in the Avatar state, the reincarnation cycle will be broken and the Avatar and the protectors will cease to exist."
