The train pulled to a stop. Harry reached out to open the compartment door. A large piece of parchment magically rolled down in front of the door.

Dear Mr. Potter and Friends,

Please wait in the compartment. Someone will be there to get you. The other students must not see Yuna and the others until tomorrow.

Professor Albus Dumbledore

"Looks like we have to wait." Ron sighed.
They sat in the compartment for what seemed like an hour. Harry looked at his watch.
"The feast must be over by now." He moaned.
"Please don't mention food," Tidus said rubbing his stomach, "I'm starving."
"Tidus, you're always hungry." Lulu said rolling her eyes.

The compartment door slid open. Dumbledore, followed by Professor Mcgonagall, walked in.
"I'm glad to see you all made it safely." Dumbledore said beaming.
"Would you please explain to us why you brought us to another world?" Tidus asked standing up.
"That will be revealed to you when we reached the school, now let's go."
Yuna started to pick up her owl's cage but Dumbledore shook his head.
"That won't be necessary Milady, your things will be brought to the castle for you."

They exited the train. They started towards the lake.
"We'll be entering the school be boat." Professor Mcgonagall explained pointing to a large rowboat.
Everyone climbed into the boat. Soon they were out on the lake. Yuna kept peering over the edge in curiosity.
"Milady, will you please sit down?" Mcgonagall asked. Yuna sat back down.
"Sorry." She said quickly. At that moment a huge tentacle rose out of the water and wrapped around Yuna's throat.
"AHHHHHHHHH!!!!" She screamed as it yanked her out of the boat and into the black water.
"YUNA!!!" Tidus cried diving into the water.
"Hang on! We'll save you!" Wakka yelled diving in after him.

The boat was in silence. Lulu, Harry, and Ron were watching the water eagerly while Hermione was sobbing.
"Do you think they'll be alright?" She choked.
"Damn giant squid!" Mcgonagall yelled, "I knew having it here was a bad idea!"
At that moment Yuna and Wakka both climbed into the boat gasping for air.
"Where's Tidus?" Harry cried.
"He's still down there," Wakka said climbing back into his seat, "He said he'd hold it off while we escaped."
Bubbles were forming on the surface of the water. Then they vanished.
"Lady Yuna I'm so sorry." Dumbledore said grimly.
"I-I feel so awful." She whispered.
"Your guardian..."
Yuna smiled. "I meant for the squid."
As if on cue Tidus leapt out of the water, sopping wet. He shook his head back and forth like a dog spraying water everywhere.
"Watch it!" Ron yelled shielding his face.
"Is it dead?" Hermione asked nervously.
"No," He answered, "I just stunned it."
"This is odd," Mcgonagall whispered, "The squid has never attacked anyone before."

That reached the castle without any more incidents. They walked into Professor Dumbledore's office. He motioned for them to sit down.
"Now," He started, "You're probably wondering why I brought you here, well the story begins with a wizard named Voldemort."
At the mention of Voldemort Harry, Ron and Hermione all shuddered.
"About 14 years ago Voldemort was an evil sorcerer," Dumbledore continued, "He began to get some followers and brought them over to the dark side. Any wizard or witch that stood up to him was killed." He motioned towards Harry, "Harry's parents fought against him, but late one night on Halloween, he showed up in the village where Harry and his family lived. Harry wasn't even one-year-old yet, he broke into the house and killed both of Harry's parent." At these words Yuna gave a gasp of horror. "He then turned his wand on Harry, Harry would've died, but something strange happened, the spell reflected off of him and hit Voldemort instead, at that moment Voldemort's powers were destroyed and he vanished."
"What does any of this have to do with us?" Tidus asked.
"Let me continue," Dumbledore said calmly, "He was gone for 14 years, but last year he preformed a spell and got his body and powers back, this could mean the end of mankind, but right now he's focusing on getting revenge on Harry, that's no ordinary mark on his forehead, that's the spot where the curse touched him."
"That would explain the weird shape of it." Tidus said in awe.

"But how does this connect to us?" Yuna asked.
"Voldemort has been searching for power lately," Dumbledore continued, "And he's getting it, so I've brought you here not only so you can learn more advanced magic, but so you can also teach the other students."
"Teach them what?"
"How to summon Aeons of course! If the students learned how to do this then they could defend themselves against Voldemort if the time should come, if you don't want to do this milady I understand, I'll send you straight back to Spira and you can get on with your lives."
"I'll do it." Yuna said without hesitating.
"Excellent!" Dumbledore said clapping his hands together, "But I must warn you, you are the most powerful summoner in the universe, but you are still in mortal danger."
"What?!" Tidus cried, "Why?!"
"Voldemort knows about the summoners and their powers," Dumbledore said gravely, "He must know by now that Yuna has come to Hogwarts, if he finds her he will be able to absorb her powers, if that should happen Yuna will have the life force drained from her body and Voldemort will become unstoppable."
"I'll still do it." Yuna said calmly.
"Then you shall be sorted at once." Dumbledore said taking an old hat off the shelf.

"Just place this on your head," Dumbledore told her, "It will tell you what house you belong in."
"What houses?" Wakka asked.
"The four houses of Hogwarts, they are Gryffendor, Ravenclaw, Hufflepuff, and Slytherin."
"Pray that none of you get into Slytherin." Ron whispered.

Yuna pick up the hat and placed it on her head. She jumped when it started to speak.
"Hmm... yes a good mind, lots of courage, ok GRYFFENDOR!!!"
Yuna took of the hat and smiled.
"Good for you Yuna!" Hermione said smiling, "Me, Harry, and Ron are all in Gryffendor too!"
Wakka was next. The hat barely touched his head when it yelled, "GRYFFENDOR!!!"
Lulu got into Gryffendor too. Finally it was Tidus's turn.
"Hmm..." The hat said, "You seem to have a lot of each house inside you, but where would you do best?"
"How about Gryffendor?" Tidus whispered, "It's my duty to protect Yuna so I should be in the same house as her."
"Ok then. GRYFFENDOR!!!"

Tidus yanked the hat off his head and set it down on the desk.
"The reason I wanted you all to sit in the same compartment is that I hoped you'd all become friends," Dumbledore explained, "That way the three of you could show Lady Yuna and her guardians the important rules and places in Hogwarts. Now go to your dormitory and get some sleep."
"Um, professor?" Harry asked.
"The password for the common room is bibliophile." Dumbledore said calmly.
"Thanks."

"What the bloody hell is an Aeon?" Ron asked as they walked down the hall.
"Ron watch your mouth!" Hermione snapped.
"An Aeon is a magical creature you can summon to help you in battle," Yuna explained, "They can be powerful allies if you know how to use them."
They came up to a portrait of a fat lady.
"Bibliophile." Harry said. The portrait swung open to reveal a crawlspace. They climbed through it and entered the common room. It was empty. A roaring fire was in the fireplace.
"The girls dormitories are up the stairs to the left, boys to the right." Harry said sounding like a prefect.
They made their way upstairs.
"I'll see you all in the morning I guess."
