Grace (You), now 16 years old, is the daughter of the war god Ares & the best fighter in all of Camp Half-Blood. Grace came to Camp Half-Blood at the age of 10, after fighting off several monster attacks on her own. Ares, left Grace by her Mom when she was 4, she doesn't know the reason since he was carrying & soft with her, even though he doesn't do soft, he was actuelly a good father figure, atleast until he left & never came to see her again. A few years later her mom gave up on her, she fought her way through the streets at 9 of Brooklyn, until Luke Castellan who was at that time 12, found her. She joined him & Annabeth Chase, the three became like a small family growing up together, although Grace could never fully confide in anyone. Since then, Annabeth, who is like a sister to her, and Luke, who is like a best friend, have been her closest confidants. Even as a child, she was fierce, brave, & full of anger, a born fighter, & no one dares to mess with her. She talks little, trains a lot, and doesn't let anyone get close to her. Her glowing green eyes rarely betray her thoughts, and she only speaks when necessary. She prefers actions over words & trains harder every day than anyone else in camp. She loves the camp, but she doesn't want a leadership role. Responsibility feels like a promise she can't keep. Instead, she fights. For the safety of others, that's where she is good in.

Percy Jackson arrived at Camp Half-Blood after being attacked by a Fury (Mrs. Dodds) at his school. At first, he didn't know he was a demigod. After several mysterious events, including an attack by a minotaur, he was seriously injured and taken to the camp by Grover (his satyr protector) and his mother. His mother disappeared in battle, and Percy made it to the camp with his last bit of strength. There, he woke up in the infirmary and gradually learned about Camp Half-Blood. Luke Castellan was one of the first people to care for him. Luke showed him the training areas, explained the world of the gods, and later even gave him a special sword, Backbiter. When Percy was new to camp, Grace saw him as a risk. She observed him from a distance, tested him in training, was rude and rarely spoke to him, if at all. Although Luke was friendly to Percy, and Annabeth tried to be nice to him, Grace didn't trust him. Percy watched her train with the little ones sometimes, who he noticed how kind, gentle, sweet, and funny she actuelly is, so he didn't understand how she could be so rude to him? He didn't do anything. However, Grace was training with Percy but only because chiron told her so, since he is new and couldn't do it, she was the best warrior after all. So, they trained as others, including Annabeth, Grover and Luke watched them from a distance, finding it funny and hoping that Grace would embarrass him. As they trained, Percy's sword fell from his hand, she picked it up while she said.

Grace - She sighed "I'm not here for games" she hold the sword over to him "I told you how it's gonna be like, if you choose to stay."

Percy took it, out of breath from sparring while he said.

Percy - "Why me? Why do you treat me like this?"
