The Argo II was flying to Camp Jupiter. The seven decided to have one last trip there to drop off Hazel and Frank.

"Its to bad we have to go back already." Hazel sighed.

"It's okay, we could always hang out with them again some time." Frank replied. The ride was slow and felt like it was taking a million years.

"Lets go get some thing to eat." said Hazel. They walked below deck to the dining hall to find Annabeth and Percy playing rock, paper, scissors while Jason and Piper were sharing a milkshake.

"Hey Hazel, how are you about going home?" Piper asked after seeing the two walk into the dining hall.

"Wishing that we didn't have to go home right away." Hazel said. Annabeth looked up at Hazel.

"It's okay Hazel, you don't have to worry about any thing it will be fine." She then turned and threw rock, which beat Percy's scissors. Percy frowned.

"How do you keep winning at this?" he asked looking at her with amazement.

"You should throw something that isn't scissors Seaweed Brain." she smiled happily as he got ready again.

"Okay, three, two, one, and..." he was interupted by a violent rocking of the ship. Leo came in, falling down the stairs.

"Guys we have a major problem on deck NOW!" he yelled. He ran up the stairs, followed by the crew. They stopped and gasped at what they saw. It was a spinning black vortex in the middle of a field.

"Leo where are we?" Annabeth demanded. Leo ran to a mini computer with a Anti-Monster Protection app on it.

"We are in Kansas right now!" he cried above the wind howling. Jason's eyes widened.

"There is something in there!" he screamed a giant white kite flew out of the vortex. Percy uncapped Riptide, Annabeth and Piper drew their swords, Hazel whistled for Arion, Frank drew his bow, Jason summoned a shield made of wind around the crew, and Leo pulled a sledgehammer out of his tool belt. The white kite flew up to them.

"Do not fear me, I will not hurt you." It said as it flew around them.

"Then why is there a dangerous, black vortex?" Leo screamed.

"It is the only way I could come here, but come now I need you to help someone." the kite said.

"Look lady you should go back to your home now" Piper said putting charmspeak into her words.

"Charmspeaking will not work on me Piper McLean, for I am Raava the Light Spirit, I will be honest you may lose some abilities if you come with me, but it is to help my world, I promise no time will pass when you are there come now." she flew up in the air and hovered over the crew.

"I'm in" said Annabeth

"What?!" asked Piper

"It's a light spirit" Jason stated

"And I have a feeling she is telling the truth."

"So are you coming?" Raava asked.

"Yes" replied the Seven.

"Hurry, it's almost over!" cried Raava as she flew and picked up the seven. She flew towards the vortex.

"Oh my gods!" screamed Hazel as everyone cried as they were sucked into the vortex. Inside it was a green portal to the sky, and Raava flew into it, with the seven on her back. They went flying through the air, spinning, flipping, screaming, and of course falling.

*Meanwhile*

"Hurry Harmonic Convergence is almost over." said Raava as she flew up to the spirit portal with a girl on her back.

She flew to the top of the arch of spirit lights and touched the portal. Everywhere was filled with flashing colors as the girl floated down and gently landed on the ground.

"Good to have you back Raava." she said as she regained her strength.

"It's good to be back Avatar Korra, and I brought help to you." The Light Spirit replied. Korra looked around seeing only her friends Mako and Bolin, her cousins Densa and Eska, her airbending master Tenzin, and his sibling Bumi and Kya.

"Who is it then?" Korra asked wondering what the Light Spirit had planned.

"Who mean who are they." The Spirit added as a light shot out of the Tree of Time. With it came seven teenagers. There was 3 girls and 4 boys there.

"Who are you?" asked Korra as she ran up to the group who was shot out of the Tree of Time.

"I'm Percy Jackson, I am here with my friends Annabeth Chase, Leo Valdez, Frank Zhang, Piper McLean, Hazel Levesque and Jason Grace." said one of the boys. Another one who Korra thought was Leo looked up and said

"We're not in Kansas any more".

"What did Raava do?" asked Korra fearing something bad was going to happen not only to her, but to all of them she had sent.
