Chapter 17
Disclaimer: I unfortunately don't own Percy Jackson or Harry Potter, the belong to JK Rowling and Rick Riordan

Percy POV:

"I'll support myself in the air with the water vapour. I can support you for a short amount of time and then if you don't succeed those three can catch you." I explained.

I made all the water vapour in the air into a platform that would just about support me if I controlled it that way. I picked up my cousin and we rose slowly to by the ceiling. Then on the count of three I let Thalia down, about halfway down she faltered and seemed to fly slightly but didn't seem to be in control an she slipped and Frank and Hazel caught her before she hit the ground.

I started to slowly lower myself back to ground level and when I reached the floor I collapsed in exhaustion. I couldn't do that with vapour again. But I probably could support myself on liquid water.

We floated up again and this time Thalia was better prepared and managed to control her flight a bit more.

"Really, what we need is the Grand Canyon. That's how Jason learnt to fly." Annabeth said.

"No, you're not dropping me out a window."

We carried on as before and on the tenth attempt Thalia managed to remain levitating in the air. You could see she was concentrating hard and when the rest of us broke her concentration by clapping she fell, but Frank caught her.

"Thanks" she said.

"No problem. I'd never drop my auntie on the floor." He chuckled.

Thalia didn't seem amused by this statement but we kept on trying to make her fly. We spent the next two days training Thalia in flying whenever we had free time and Zeus knows how many attempts later, Thalia was successfully flying around the room, but she still had concentrate really hard.

On the third day we were making progress, Thalia was flying with much less concentration, instinctively like Jason does. Frank turned into an eagle and the three of us - me supported by my water disc, Thalia proudly showing off her flying, and a huge bird - were flying around. Annabeth and Hazel were cheering on the ground below.

"Mission accomplished!"

Ginny POV:

I was sat alone in my dorm, trying to do my Astronomy homework when I heard cheering in the room above me along with what sounded like a large bird of prey screeching. I was really confused so I went upstairs to investigate what was happening.

I went into the dorm and a bizarre sight met my eyes. Annabeth and Hazel were jumping up and down in joy, high fiving each other and saying "Mission accomplished." But that was the least weird part. Percy was standing in the middle of the room but he wasn't actually on the ground. He was levitating about a metre and a half off the ground. He was standing on what looked like a disc of water and he was circling the room while dancing.

Nearby Thalia was flying around the room, from looking you would have thought she was on a broomstick but there wasn't one there, she was flying in the opposite direction to Percy and whenever they crossed paths they would high five and then carry on. Thalia seemed occasionally to wobble slightly as if she was just learning to fly but mostly she seemed to be enjoying herself.

By far the most bizarre part of the scene was the animal flying around, as I watched it went from eagle to seagull to blackbird to hawk to miniature dragon and then back to an eagle. The others seemed to think of the bird/dragon as a normal occurrence so were ignoring it.

It flew around for awhile and the others continued dancing and flying until I cleared my throat. All four of them and the bird stopped and looked at me. Then lots of things happened at once. The bird landed and where I was looking all of a sudden the bird turned into Frank. Percy was so surprised that the water seemed to stop holding him and he fell through the air, meaning Annabeth had to stop celebrating to catch him. Thalia stopped flying around and sat down, in the air.

"What the hell is going on in here?" I asked.

"We were teaching Thalia to fly, you see her brother Jason can fly but she couldn't so we were teaching her." Annabeth said

"As you can probably see I just managed to fly without concentrating." Thalia said.

"You might want to be careful or other people will find out. And Frank, you should register as an animagus." Said Ginny.

"What's an animagus?"

"A person who is registered to be able to transform into an animal. The animal that your patronus takes the shape of, is what you would be as an animagus. Only a few people can become animagi." Said a voice behind me. Thalia jumped a few feet out of surprise and then fell onto the ground. Harry came into the room followed by Hermione, Ron an Neville. Luckily only Harry seemed to have seen the flying.

"Yeah and out of those who are animagi, not all decide to register. They are illegal animagi." Hermione said looking at Ron and Harry.

"Are you-" Percy asked.

"No, my pet rat actually was a servant to the dark lord." Ron explained.

"And my dad and godfather were unregistered animagi too, dad was a stag and Sirius was a dog."

"Anyway, I was just going to tell you that the goblet of fire has been placed so we were going to watch who enters, want to come?" Ron said.

"Okay, Annabeth replied. "We'll be down in a minute."
