Percy stared at the girl. How could she not be his sister? They had lived in the same cabin, well, only for a couple days, but still! And, wait, didn't she say her last name was Jackson? And what was this Child of the pantheon stuff? The girl continued, "My mother, Sally Jackson, was courted by Poseidon, Zeus, Hades, Apollo, Hephaestus and Ares. My father, unknown, was courted by Aphrodite, Athena, Demeter, and Iris. He was banished to Tartarus for reasons I wish not to go into. Very soon after I was born, my mother was visited again by Poseidon, and my brother, Perseus Jackson was born." Percy's mouth fell open. He had a sister? How could he not have known? But Aria continued to speak, "I attracted so many monsters that soon my godly parents brought me up to Olympus to be raised. The last time I saw Percy was when he was 3. The gods wiped his memory of me so as to keep everyone safer. I wasn't allowed to leave Olympus except for special occasions, like swim meets or to see my mom. The only exception was when I was thirteen. I-I was in downtown Manhattan and, well this was during the rise of Kronos, so a group of monsters leaped out at me. They surprised me and had the advantage. They took me to Luke and tried to turn me to their side. I wouldn't change no matter what they did. When Luke found out who I was through very painful interrogation, he deemed me too dangerous to have fighting against, so, so I was thrown into Tartarus. I made it through by myself, it took me over a year, for the doors of death kept moving. Everyone thought I had died, but I came back. During the Titan War I was to stay on Mount Olympus and defend it from monsters who made it up the elevator. Then, during the war against Gaea, I was to keep the camps separate. Some of you might have occasionally seen me running around, but I mostly stayed in the shadows." Everyone's mouth was hanging open now, as she walked out of the pavilion and back to Cabin 3. Finally, Clarrise yelled, "Now wait one minute. Why the Hades did she have the right to lie to us? I want more answers! I want to know why she didn't come to camp half blood before, and why she wasn't helping out more during the wars! If she's the so called child of the pantheon, then why were we the ones dying?" The camp roared in approval, and Leo snuck away to seek out his friend. Chiron tried to settle the campers down, but he couldnt do anything. The Demeter campers grew vines around his hooves so he couldn't stop them. Then, the Camp headed out to Cabin 3, with weapons raised high in the air.
"Aria!" Aria turned around to see her elvish friend chasing after her. "Leo," she said, but Leo simply grabbed her arm and started pulling her towards the woods. "Aria, the whole camp is after you. We need to hide in Bunker 9. It'll be same because I'm the only one who can open the door." Leo pulled Aria fartther and farther. Finally she spoke in almost a whisper, "Even Percy?" Leo slowed for a moment. How could she be so caring and protective of a brother that she hadn't seen for 14 years? "Um, I'm sure he's just following them so he won't get hurt." Okay, so that sounded nothing like what Percy would do, but Aria didn't know that. All of Leo's concern was getting her safely away from the camp on rampage.
"Now, my evil spirits, while the camp is turned against her. Now is the time to attack, while the camp is together."
Percy was mad at his, apparently sister. He was mad at his mom. He was mad at his dad, Poseidon. He was mad at Grover and Chiron. They had all kept a secret this big from him for so many years, and he wanted answers. He was half way to his cabin before he realized that every once I a while a Camper would stumble, then regain composure, and their eyes would be golden. Too late Percy realized what was happening, and then an eidelon possessed his own body.
Night passed, and early morning came to Camp Half Blood. Leo was still asleep, but Aria was wide awake. She had to see the campers for herself. She had to see if Percy was against her. Aria snuck over and turned off Leo's alarm clock so he wouldn't get up and worry about her. Then, she scrawled a note on a piece of paper and left the cabin. Thank the gods she had inherited the same power as Leo from Hephaestus, so she could get back into the Bunker. Aria shadow traveled through the woods and ended up on the edge of Camp. What she saw made her catch her breath. The entire Camp had gold eyes, and Aria knew what had done it. She'd tangled with enough eidelons to know what they did. She didn't know how long she'd been standing there, but knew she was in trouble when a golden haired boy with a roman gladiator sounded the alarm, Jason. The gods had told her all of the Heroes of Olympus' names. As soon as Jason shouted that Aria was on the hill, all of the Camp started heading toward her. Percy had riptide drawn, Nico, his Stygian iron sword.
Leo woke up early, and the. Noticed Aria was gone. He ran over to her bed and quickly skimmed her note. Blah blah blah, see the camp, blah blah blah, talk to Percy hopefully, blah blah blah. Leo grabbed Festus and hurried out of the Bunker.
Leo noticed all of the campers had gold eyes. Oh Styx, eidelons. Well, he might as well follow them and pretend to be possessed, too. Which wasn't too hard considering what had happened on the Argo II. He followed all of the campers up a hill with Festus in tow. At the top was Aria, faci odd with Jason, Nico, and Percy.
Aria looked at her brothers, because technically if you count all of the godly stud they were all her brothers, and raised typhònas. "Ah, if it isn't the child of the pantheon." A female voice said from behind the three boys. Everyone's least favorite snow goddess stepped forward. "Really Khione? Didn't the gods, like, punish you or something?" Khione snarled, "My master Ouranos released me from my prison." Aria snorted, "You really didn't learn from last time? Your seriously going to fight against the gods again?" Khione growled, "You three, attack." She said, gesturing to Percy, Jason, and Nico. They all nodded and summoned something. Nico summoned a wall of shadows, Percy, the entire lake, and Jason summoned lightning. They all sent their element at Aria, but she intercepted them. She held the lightning, water, and shadows at bay, but she could feel it draining her. What was she going to do? Aria didn't want to kill anyone, but she couldn't hold her own for very much longer. She raised in the sky and made up her mind. Aria threw the lightning at Percy, the water at Nico, and the shadows at Jason. Then she blacked out and fell to the ground.
Leo ran forward to his friend. She was completely out of it. Leo called to Festus, loaded Aria's limp body on, climbed on himself, and they were off in record time.
