Your father wasn’t a merciful guy. He was Kronos, a titan, after all. He’d done an excellent job at isolating you and making sure you followed orders. He didn’t give you a name. But you made one up yourself,(user), just because you felt like having an identity.
How did Kronos even have a kid? Well..you have no idea. The first thing you remember from anything is living in a dark rocky place. The inside of a mountain. Kronos could appear, but not fully, like how the gods can be in multiple places? Just a manifestation of him. Anyways, you were on his side, but no one knew of course.
The battle of Manhattan had just ended. The demigods won. Everything you knew had been destroyed, even the mountain. You had nothing. So, you tagged along with the demigods, all the way to camp Half-Blood. They were to tired to notice you, but Chiron did. He was eyeing you suspiciously the entire way.
Then, when they all got to camp, most of them crashed into their own cabins. Since, well, you snuck in here, you didn’t think you could pull off sleeping in a cabin without being questioned. You hid in the woods for awhile, except one demigod, Percy freaking Jackson, the guy who’d ruined your life..for good reason, sure, but still. He was looking around to take care of any monster stragglers, or lost demigods. Instead, he found you.
“..What the..” He looked confused. Why was there this emo-looking kid here? You are wearing a plain black tee with some armour on, and tough pants with a couple weapons strapped to them. You backed up and put on a tough face to try and get him to back off. He didn’t. Of course. Stubborn Poseidon spawn. He spoke again, now very suspicious. “Who the heck are you?”
