No one's POV
1788
Carter Sparrows, the daughter of Poseidon and a mortal woman has been born. On her 12th birthday, her dad claimed her. By then, monsters had started attacking from every corner. Her mom sends her to Camp Half-Blood. She trains there, and becomes a skilled demigod not only with swordplay but also with her inherited powers from her godly parent. On a particular day at camp, monsters had attacked near the beach. All campers rushed over to protect the camp. Carter, being the only one who could control water, uses the beach to her advantage.
"Attack the monster! I'll do my best to hold it back from the borders with my power!" She shouted to the campers. They all nodded in agreement and got their armory while she distracted the monster.
After a few hours, the campers started falling. They were losing more than they could spare already. Carter had fallen to one knee, struggling hard with the monster (who by the way, was a Minotaur.) It's pretty hard to believe she could hold on that long, considering the Minotaur was pretty big.
Mark, her half-brother, was fighting the Minotaur on his weak sides with a sword. Out of the corner of his eye, he saw Poseidon appear near the beach. Seeing his sister fall on both knees, he called out, "Father!" Poseidon looked at him with a concerned look on his face, like he wanted to do something to help but wasn't sure if Zeus would allow it. He also had that pride-ish and stunned look on his face, like he was proud of her heroism. "You have to help Carter!"
Just then, Zeus appeared beside his brother. "Brother Poseidon," his brother turned to face him. "Go on. She deserves it."
With those words, Poseidon stepped forward and sent a whirlpool around his daughter. She release her grip on the monster, and Zeus killed it with a lightning bolt that he summoned from the sky. Pretty soon, the girl was glowing green, and she felt a strong flow of newfound energy within her.
Zeus noticed how long it had been, and laid a hand on Poseidon's shoulder. "Brother, enough." He stopped the whirlpool, and Carter collapsed on the sand, unconscious. "She won't be able to take it all at once." Poseidon nodded in agreement. And with a flash, Zeus went back to Olympus.
Mark had rushed over to his sister's side, concerned about what happened. When his father walked over, he asked,"What happened, Father? What was that glowing thing? And what is with the whirlpool?"
"One question too many. I'll answer your questions when I get back. By then, she should be conscious. I just need to do something." He walked back to the beach until it was head-level and disappeared.
Chiron and the campers helped her to the Big House along with the other wounded campers. Word had leaked about that little "episode" on the beach, and rumors were starting. Mark didn't care, he just wanted to know if his sister was okay or not.
