I woke up with the hard, cold floor to my face. "Who ever did that better start running now." I muttered darkly. I heard the person taking rapid steps away from me; I looked up to see Annabeth shaking her as she watches her boyfriend run away from me, his own twin sister.

"I told him not to do that," Annabeth shook her head. Any person who knows me knows that I'm not the most pleasant person when woken up the hard way and/or on the wrong side of the bed.

"What's the matter? You know I don't appreciate being woken up."

"Chiron wants a meeting at the Big House; it's about a new quest."

"Ugh." I stood up lazily. "Give me five minutes." Annabeth nodded and left me alone.

Before I continue on, I should tell you that my name is Ariana. Ariana Celeste Jackson, the twin sister of Perseus "Percy" Jackson. I basically look like the girl version of Percy with black hair that goes down to my waist. In some ways, I'm just like my brother; I am dyslexics and ADHD. But I'm also different from him; I got brains that could be mistaken to be Athena's daughter, and I don't get in trouble a lot like my brother. Unlike him, I got expelled only three times which way, way less than him. Most of the time, to control my ADHD in school, I draw what ever it is that the teacher is saying or what I'm thinking. You see, on top of being ADHD and dyslexics, I am also a visual and kinesthetic learner; I think in pictures and learn things best when I'm doing them. Which is sometimes a pain since whenever I'm drawing, my teacher sometimes takes my paper and pencil away, because they think I'm not paying attention. It also doesn't help that I'm addicted to music and anime.

Anyway, back to the story (I get side-track really easily). Five minutes later, I entered the Big House. I wore straight light-blue jeans, my bright orange Camp Half-Blood shirt, and a black vest over that and a pair of black converse. My weapon, or rather weapons consist of a silver-bordered cerulean-blue ring that transform into three and a half foot long celestial-bronze sword (I call it Hayate which means Hurricane) and a matching necklace that turns into a half celestial-bronze, half metal three and a half foot long sword (this one I call Tsunami.) I have had them since I was a baby, and I didn't know the significance of them until I discovered I was a demigod. Most of the time, weapons like these are given to demigods once they realize they are one, but since I'm the first demigod daughter of Poseidon, he gave this to me when I was born.

"Now that we're all here, we can begin. Lord Hades and Lady Hecate request this quest themselves. Long ago, Hecate blessed 100 mortals with magic, making them wizards and witches; these 100 mortals populated and created a world which non-magical people could not get access to, like our world. Four of these mortals are in England and started a school that teaches wizards and witches alike; it's called Hogwarts," the room snickered at the name. "These four people are Salazar Slytherin, Godric Gryffindor, Helga Hufflepuff and Rowena Ravenclaw. They were the first teachers of Hogwarts and they later became the four houses of the school. Each house represent a character: Slytherin - sly, Gryffindor - brave, Hufflepuff - friendly and Ravenclaw - intelligent. The Slytherin house believes that only pureblooded wizards are the only ones that should be taught magic, while the others disagree. That's where the problem starts.

"There was a boy in the Slytherin house named Tom Marvolo Riddle; he was a muggleborn, a wizard whose parents are muggles, a non-magical person. As he study at this school, he became dark, and he begins to believe that only a pure-blood should be the only one to be taught magic, thus the birth of Lord Voldemort," more snickers. Seriously, these wizards needs to come up with better names, I thought. "He sets out on a mission on killing every muggleborn and half-blooded wizards." The laughter stops and the room became silent with dislike to the Dark Lord. "One night he went to kill a baby boy that's said to be destined to stop him; however, that plan backfired. Saved by the love of his parents, the boy, Harry Potter, survived; the killing spell, Avada Kedavra, reflected back on Voldemort, leaving Harry an orphan, with a lightning bolt scar on his forehead to absorb some of his powers. Although he was gone, he was not really dead."

"What do you mean he's not dead?" asked Nico.

"Before he died, he split his soul into seven horcruxes. In order to truly kill him, all seven must be destroyed." No wonder Hades is pissed; someone cheated death, I thought.

"Lord Hades and Lady Hecate requested this to the gods, and they agree that he must be stopped. So they came up with a group of demigods to help kill Voldemort. Percy and Ariana Jackson, Annabeth Chase, Nico di Angelo, Thalia Grace, Travis and Connor Stoll, Clarisse la Rue, Mary Lou, Katie Gardner, Piper McLean, Leo Valdez and Will Solace. You all will be going to Hogwarts and stop Voldemort from rising. Although he is considered a powerful wizard, he is next to nothing when compared to Kronos and Gaea. Any questions?"

"How are we going to get there?" asked Annabeth.

"Plane." Nico, Percy, Thalia and I paled. Nico, my brother and I had a legit reason to pale: children of Hades + children of Poseidon + Zeus's domain = dead demigods. If it's on a Pegasus, then no problem, they are neutral ground (I ride them every morning at camp.) However, Thalia's reason is so not expected from the daughter of Zeus; she is afraid of heights, which is odd because if you think about it, you would think that being the child of Zeus you like to fly. But not Thalia. "Or would you rather take the Pegasus?

"Pegasus," replied Percy and I. Nico was contemplating what he prefers since the Pegasus hates him; Thalia didn't reply, because her main reason is heights. I think they both would have preferred the plane since it was safer than the Pegasus; however, I completely disagree.

"Oh, and one more thing. You need wands; place your preferred object into this box, and it will turned into a wand that is suitable to you." One by one this did as we were told. "In order for that object to become a wand all you have to do is picture is as a wand. For those whose object can transform into a weapon, think of it as a your weapon in order for it to become a weapon and a wand for it to be a wand." Chiron explained further.

I put my ring back to my finger. My wand was a 10-inch maple wood with the core of Pegasus hair and mermaid scale; its color was oceanic blue. Percy's was almost the same except his wood is birch and the color was kelp green (it had the same core and length.)

"Gather by the stables within two hours. Leave your baggage by the front door of the stables; they will be transported to your rooms while you are flying. Good luck."

I fed Levánta and the other Pegasus snacks while I wait for the others to arrive. Levánta is my Pegasus, by the way; her name means lavender in Greek even though Levánta's coat is pure white. She is as white as Blackjack is black. The reason for her name is quite simple actually; if light hits in a certain way, it would seem like her pure white coat and feathers is lavender. She is, in many ways, the opposite of Blackjack; he is casual, whereas Levánta is formal; he is playful, she is serious; he is black, she is white. But one thing they have in common is that they are both loyal to Percy and me.

Where are we going this time, my lady? She asked in my mind.

"We are going to Hogwarts, school of Witchcraft and Wizardry in London," I replied.

Hogwarts? That is a strange name for a school. For what reason are we going there for?

"Apparently Lord Hades and Lady Hecate ordered this quest themselves. We're supposed to help them fight a dark wizard who calls himself Lord Voldemort who had been killing wizards and who had escaped death."

Oh, that is bad. And wizards have a peculiar way of naming themselves and places in particular.

"Yeah. Needless to say, they are both angry."

The others arrived just after I finished grooming, feeding and preparing the Pegasi for the trip.

"Is everyone ready?" I asked.

They all answered yes except for Nico and Thalia. I rolled my eyes. No sooner we mounted the Pegasi and took off.
