has a plan." She then turned to Y/N with her eyebrow raised. "More importantly, how did you do that?" Y/N stared back at her, confused.

"Do what?" he replied.

"You make those Ares kids hesitate just with your voice," Annabeth explained. "And that rush of heat? I felt it too." She looked at him suspiciously. "Are you sure you're not charm speaking?"

"I don't think it was like that," Y/N mumbled. "I think she was just saying it out of guilt." She looked at him, still studying him, before turning to Percy. "I came as fast as I could. I was about to jump in, but..." She shrugged. "You didn't need help."

Then she noticed his wounded arm. "How did you do that?" She questioned.

"Sword cut," Percy said. "What do you think?"

"No. It was a sword cut. Look at it." Y/N added. The blood was gone. Where the huge cut had been, there was a long white scratch, and even that was fading. As he watched, it turned into a small scar, and disappeared.

"I-I don't get it," Percy stammered. Annabeth was thinking hard. Y/N could almost see the gears turning. She looked down at Percy's feet, then at Clarisse's broken spear, and said, "Step out of the water, Percy."

"What-"

"Just do it." Percy walked out of the creek, and immediately stumbled. Y/N caught and steadied him.

"Oh, Styx," Annabeth cursed. "This is not good. I didn't want... I assumed it would be Zeus..."

Before Y/N could ask what she meant, he heard that canine growl again, much closer than before. A howl ripped through the forest. The campers' cheering died instantly. Chiron shouted something in Ancient Greek, which Y/N would realize, only later, he had understood perfectly: "Stand ready! My bow! "Annabeth drew her sword. There on the rocks just above them was a black hound the size of a rhino, with lava-red eyes and fangs like daggers. It was looking straight at Percy.

Nobody moved except Annabeth, who yelled, "Percy, run! "She tried to step in front of him, but the hound was too fast. Y/N's mind raced with urgency as the hound bounded towards Percy, its mouth full of razor-sharp teeth.

"PERCY!" Y/N screamed. He dashed forward, holding his hand out. A blast of heat washed over him, and the torches roared with flames. The fire seemed to lash out, blasting the hound with bronze-colored flames. The hound hissed and writhed in pain as it melted, its body disappearing.

Nobody spoke as the flames died down. As Y/N returned from his adrenaline high, he stumbled forward, his mind reeling with dizziness. Chiron trotted up next to him, steadying his arm. The sound of silence covered the camp as nobody said anything, too stunned to speak.

"Di immortales!" Annabeth exclaimed. "That's a hellhound from the Fields of Punishment. They don't...they're not supposed to..."

"Someone summoned it," Chiron said. "Someone inside the camp. "Luke came over, the banner in his hand forgotten, his moment of glory gone.

"It's all Percy's fault! Percy summoned it!" Clarisse yelled.

"Be quiet, child," Chiron told her. They watched the body of the hellhound melt into shadow, soaking into the ground until it disappeared.

"You're wounded," Annabeth told Percy. "Quick, Percy, get in the water."

"I'm okay." He muttered.

"No, you're not," she said. "Chiron, watch this."

Percy stepped back into the creek, the whole camp gathering around him. Instantly, he stood up straighter, and cuts began to close on his arms and chest. Some of the campers gasped.

"Look, I-I don't know why," he said, trying to apologize. "I'm sorry...."

But they weren't watching the wounds heal. They were staring at something above Percy's head. A bright...fork?...no, a trident, shined above his head, encased in a bright green arua.

"Percy," Annabeth said, pointing. "Um..."

By the time he looked up, the sign was already fading, but Y/N could still make out the hologram of green light, spinning and gleaming. A three-tipped spear: a trident.

"Your father," Annabeth murmured. "This is really not good."

"It is determined," Chiron announced. All around him, campers started kneeling, even the Ares cabin, though they didn't look happy about it. Y/N followed suit, wobbling gently onto one knee.

"My father?" Percy asked, completely bewildered. "Poseidon," said Chiron. "Earthshaker, Stormbringer, Father of Horses. Hail, Perseus Jackson, Son of the Sea God.

The camp went silent as Percy stared back at all of them, confused. Y/N suddenly stumbled forward, getting onto his hands and knees. Annabeth got up, rushing to his aid. She grabbed his shoulder, steadying him gently.

"Y/N what was that!" she yelled out. By now, the campers had gotten up from kneeling, and were staring at him intently.

"What was what?" Y/N replied.

"The thing with fire you just did! You killed the hound!" Chiron trotted over, staring at him quizzically. Y/N managed to get up, before stumbling a few steps back into Percy's arms.

"I-I...w-what?" he muttered in a daze. He glanced over at Percy, but he wasn't looking at him. He was staring directly above his head. All around him, campers began to kneel again. But this time it was different.

Everyone was whispering, their eyes wide with shock. Chiron stared back, stunned. "For the first time in so many millennia..." He muttered. Y/N followed everyone's gaze, and he saw the symbol shining above his head.

"W-What...I...who..." Y/N stammered, confused.

"Hestia," said Chiron. "Goddess of the domestic and civic, the home, sacred and sacrificial fire, family. Hail, Y/N, Son of the Hearth Goddess.
