Percy Jackson and the Boy Who Live

Chapter One, Capture the Flag

Percy crouched as he moved quietly through the monster-infested forest of camp half-blood, weaving his way between the tall trees. In his hands he clasped his sword, Riptide, in it's ballpoint pen form. One hand was holding the pen, while the other was positioned readily on the cap. He continued to make his way forwards. Up ahead he could see the creek, resembling the boarder for the two teams' territory. Three burly, armoured campers with long spears and heavy shields stared into Percy's team's half of the forest, obviously watching out for anyone that might try to cross. Their helmets had red horse hair plumes on the top. Looks like a couple of Clarisse's thugs. Percy thought.

Percy tightened a blue piece of cloth around his left arm as he looked up and to the right of him, where four campers perched in the trees. Unlike the three guarding the streams, these campers wore armour of flexible leather and had blue pieces of fabric identical to Percy's tied around an one of their arms. Three of them where boys carrying long bows with a quiver filled with miscellaneous types of arrows across their back. The fourth was a girl. Annabeth, to be exact. Her blonde hair was tied up behind her head and- like the boys- wore clothing that twigs, leaves, and grass had been woven into so that they would be harder to spot in the trees. Usually Annabeth would have worn her Yankees Baseball cap when she needed not to be seen, but she wanted to challenge herself.

She looked back at Percy and gave him a thumbs up. He returned the gesture and turned his attention to the three campers standing by the water. Just a little bit closer... Percy prayed. Just take one more step...

There was a splash in the water as a fish jumped. The guards shuffled forwards to watch it dance across the stream, coming close enough to the water for Percy to play his role. The water erupted from the stream, engulfing the Ares campers. He pulled them into the stream and held them under water, although he wasn't going to left the drown. He concentrated and willed air bubbles to form around the mouths and noses of the submerged campers. Since air bubbles stopped coming to the surface, Percy knew that the campers could breath normally. He chanced a look at the tree where Annabeth and the three archers had been, but they were already gone. Percy grinned to himself and stood tall as he walked over to the stream. He fished the campers out of the water and gave each of them a solid bonk on the helmet with a decent sized rock.

As the stood ankle-deep in the water, he examined his surroundings. Being in contact with water, Percy could see every detail in forest that he normally wouldn't have noticed. He could hear the footsteps off the rest of the campers running around in the distance, clashing swords and shooting arrows. He could see dozens of pairs of glowing eyes from the forest's inhabitants; hungry monsters that usually left demigods alone inside the camp. He could also hear the small fish in the river, talking to him in his head.

Just then there was a cheer from the opposing team's side of the creek. Percy gazed in the direction of the cheers and saw Annabeth burst through some dense bushes. In her hands was the red team's flag.

The archers were still in thee trees. They jumped from branch to branch, keeping pace with Annabeth and shooting harmless arrows coated in a numbing agent at any opposing campers that tried to stop her. Annabeth trudged past me through the water and into the blue team's territory, where she gave a shout of victory and thrust the flag into the dirt. The image of a boar's head that had been stitched into the red fabric shimmered, then transformed into a sliver banner with an owl sewn into it. A horn blew in the distance, signalling that the game had been won.

Percy stepped out of the water and rushed forwards. "You did it!"

Annabeth wrapped her arms around him and grinned. "We did it, Percy. You got the guards out of the way."

"Well, if you hadn't gone to get the flag then we probably wouldn't have-" Annabeth cut him off by kissing him.

"Shut up, seaweed brain." Annabeth teased after she broke the kiss.

He grinned and took her hand as the other campers gathered around them. Percy took a hold of Annabeth by the waist and hoisted her up onto his shoulders. The crowd was mixed with cheering and complaining.

"Good job, Annabeth!" Connor and Travis Stoll said in unison.

"You can find your way through the trees as much as any Apollo camper can, Annabeth!" Will Solace said, looking up at Annabeth.

"Thanks,Will," She smiled.

"And nice job with sentries, Percy!" Will extended his hand.

"Thanks," Percy let go of one of Annabeth's ankles just long enough to shake Will's hand, then he grabbed it again so that she didn't fall.

Campers kept coming up to congratulate Annabeth and cheer; even the majority of the red team- the campers that did not belong to the Ares cabin- said they did well.

As everyone began to meander over to the amphitheatre for the campfire, Chiron approached Percy and Annabeth, who where holding hands as they followed behind the crowd.

"Annabeth, Percy," The centaur said.

"Chiron," Annabeth smiled. "What is it?"

"I would like to have a word with you two," Chiron explained.

"Sure thing," Percy nodded.

"Be at the Big House immediately after the camp fire and sing along, alright? We have a special visitor arriving tonight."

"Yes Chiron," Annabeth said. "We'll be there."

"Good," Chiron said. "Now, run along and enjoy yourselves." He patted Percy on the back as they walked off.

"I wonder who the special guest is." Annabeth said to Percy.

"I don't know," He replied. "I guess that we'll just have to wait and see."

Percy wrapped his arm around Annabeth's waist as they walked towards the campfire, both of them very curious about who this visitor was.

About halfway through the camp fire Percy fell asleep, his head resting on Annabeth's shoulder, who was holding his hand. The Stoll brothers were finishing leading the campers in the final sing along for the evening when he woke up to Annabeth shaking his shoulder lightly. "Come on Percy, they're wrapping up camp fire; lets head over to the Big House."

Percy thought that Annabeth was so perfect that he had to keep reminding himself that she had ADHD as well, meaning that having to sit for an hour before she could meet this visitor must have been driving her crazy. Percy had felt the same way until he had fallen asleep, and now he was edging to meet the visitor as well.

"I can't wait any longer!" She said.

"Me neither." Percy agreed.

Annabeth took Percy's hand and pulled him along the path that led up to the Big House.

The moment that the couple stepped onto the front porch the door to the big house opened. No one stood in the doorway, but they could see Chiron standing in the living room. He noticed the two standing there and smiled. "There you are, right on time!" Come in and meet our visitor."

Annabeth stepped inside, pulling Percy in behind her. Instantly the door closed behind them. Percy looked warily at the wooden door, then at a figure sitting on one of the couches in the living room.

"Ah! You must be Miss Annabeth and Mr. Perseus Jackson!" The figure was an elderly man with snow-white hair and a long, flowing beard. He wore long, purple robes and half-moon spectacles on his face.

"Just Annabeth is fine, Sir," Annabeth said politely.

"And Just Percy." Percy corrected.

"Of course. Allow me to introduce myself: my name is Professor Albus Dumbledore, but only Chiron here and select other call me Albus. I go by Professor Dumbledore." Dumbledore extended his hand to the campers.

Annabeth shook and Percy followed her lead.

"Professor Dumbledore and I are good friends," Chiron said. "And is in need of some assistance."

"What kind of assistance, sir?" Annabeth asked Dumbledore.

"Annabeth," Dumbledore said gently. "You are aware of where wizardry originated from, correct?"

Wizardry? "Yes," Annabeth nodded. "The goddess Hecate blessed the population of a city long ago with a portion of her power, and the power they were given could be passed from generation to generation. They could use magic, but required wands to channel their power, unlike the goddess Hecate, who can perform magic without one."

"Very good!" Dumbledore smiled. "The reason I am here is because I and the headmaster of a school for witches and wizards, and I have three students that have been getting themselves into terrible danger in the wizarding world."

"Wait," Percy interrupted. "Sorry, but, what wizarding world? There are only a handful of people that know magic in north America, how can there be an entire community?"

Chiron answered this question. "America is in the gods' domain, so Hecate keeps an eye on all magical folk here. Over seas, where the gods have little influence anymore, people with magical powers nearly outnumber humans."

"Indeed, but Wizards and Humans are more closely related than anyone but us knows." Dumbledore said. "I know that your celestial bronze weapons will pass harmlessly through any mortal. This same thing would happen if a wizard happened to cut his or her self."

"So, if there is an entire wizarding world," Annabeth said. "Why do you need help from a couple of Demigods?"

"Because we have a very serious threat." Dumbledore said. "He is a concern to the wizarding world and the Olympians."

"Who?" Percy asked.

"You will know everything you need to know tomorrow." Chiron said.

"When school starts," Dumbledore said. "You will be attending my school as to keep an eye on the three students. No one knows about this other than the staff, and no one else can know that the Greek gods are real, or that you are half-bloods instead of wizards."

"But sir," Annabeth spoke. "You said this is a wizarding school; won't it be hard to pretend that we are wizards if we can't perform spells?"

"I have spoken to the gods," Chiron answered for Dumbledore. "And they have agreed to assist you on your quest."

"Assist us how..." Percy began to say, but went silent as blinding light filled the room. "Look away," Annabeth reminded Percy, even though he already knew what to do.

The light faded and they opened their eyes. Before them stood two goddesses. One had long brown hair and stormy grey eyes, and the other had jet black hair and green eyes that shimmered like the northern lights. The two goddesses could easily be identified by Percy as Athena and Hecate.

"Mother?" Annabeth asked, surprised.

Athena merely replied by saying, "Annabeth,"

"Where are the others?" Chiron asked nobody in particular.

"You mean other gods?" Percy asked.

"No, I mean-" The door to the big house slammed open. "Ah, I was beginning to worry that you two weren't going to show up!"

"Goat-boy over there got sidetracked in a store selling new reed pipes!"

"Hey! You're the one that used a cell phone!"

Annabeth and Percy grinned. "Grover! Thalia!" They exclaimed in unison.

"Hey guys!" Thalia said.

"Its so cool!" Grover said. "The Hogwarts I don't have to hide my legs or horns!"

"Indeed," Dumbledore nodded. "Satyrs are quite common in the wizarding world."

"You guys are coming as well?" Annabeth asked.

"Yeah," Thalia nodded. "I'm going as a wizard, but Grover is going to be assistant grounds keeper at the school."

"What do you do as grounds keeper?" I asked my friend.

"I'm not sure." He replied.

"You will find out momentarily." Athena said.

"You will have time to socialize later," Chiron said. "But right now we need to get on with the process."

"What process?" Annabeth asked.

"The process of making you inconspicuous wizards." The goddesses answered together.

"Percy, Annabeth, Thalia, Grover," Chiron said. "Stand side by side."

They did so, and Hecate stepped forwards. She held her hands up as if praying and addressed the Demigods. "As the goddess of magic, sorcery, witchcraft, crossroads, trivial knowledge and necromancy, daughter of Perses and Asteria, I, Hecate, bless you three with a portion of my powers, so that you may succeed in your quest." The lights in the room flickered for a moment before returning to their normal behaviour.

Now Athena stepped forwards. She held her hand before her like Hecate had done and said-to all four of us this time, "As the goddess of wisdom, handicrafts, useful arts, and battle strategy, daughter of Zeus and Metis, I, Athena, bless you with a portion of my powers so that you may succeed in your quest."

The lights did not flicker. Instead Percy's head suddenly began to spin with new knowledge. He shook, his head, swallowed, and blinked. When he looked up, the two goddesses were gone.

"Now," Chiron said, approaching the disoriented demigods and satyr. "For your wands."

Dumbledore handed Chiron three sticks, which Percy assumed were magic wands. Chiron stood in front of Annabeth. "These wands where made for you by your godly parents and blessed by Hecate. Annabeth, this is yours."

Chiron handed Annabeth a wand which had what looked like Greek columns etched into the handle. "Olive wood, eleven inches with a great horned owl tail feather." Chiron sidestepped in front of me. He handed me a dark wand. Along the shaft in ancient Greek was written What comes from the sea returns to the seas. "This one is very special, Percy. It is from the branch of a tree that exists in only one place on the planet; the bottom of the canoe lake. This is Called Hippocampi wood, it is ten inches long, and it's core is sea glass. But Percy, I think it would be better if you didn't tell anybody that your wand was made of Hippocampi wood."

"If they ask I'll just tell them it's made of dogwood." Percy said.

Chiron nodded and moved on to Thalia. He handed her a pale wand. It wasn't anything special, just a plain old wand. "Thalia, this is carved from the branch of your tree, eleven inches, and its core is a string from Artemis' bow." Chiron gave them a moment to look at the wands before speaking. "Hecate gave you the ability to perform magic just like any other wizard, and Athena gave you the knowledge you would need to fit in with your classmates. This includes any spells or lessons that you would have learned if you had attended the school since the first year, as well as general knowledge that most wizards your age know. Now off to bed, all of you; you have a big day of shopping tomorrow."
