Prologue

When Percy's trusted pegasus, Blackjack, came by at night, Percy found it was safe to assume he was needed somewhere. Since it was custom, Percy didn't bother to really question Blackjack when the winged horse landed outside of his cabin one night. He only became suspicious when the pegasus left camp borders and instead started to follow the Hudson River down to a seemed to be in some kind of a stupor, like he didn't realize what he was doing. Thaat little fact really became clear when the Pegasus shook its' head and looked around as if thinking, 'where the Hades am I?' and turning around.

Both pegasus and rider were stunned when instead of countinuing his flight, Blackjack suddenly stopped as if he was whacked in the head with a baseball bat. This resulted in both of them falling to the ground for a brief moment before the pegasus finally regained his balance and tried to fly through again. This time, the horse stopped at the same place again, but he had so much more momentum that he actually knocked himself unconscious and was actually free-falling down to the rapidly approaching forest floor.

As soon as Percy landed, he fainted having taken the blunt of the attack when he ended up being the first to land with his pegasus landing on top of him. He didn't wake up again until two strangers stumbled upon him.

-Line Break-

When Sabrina Grimm woke up in the morning, she didn't expect herself to really find anything new. Daphne was always more into the whole family buisiness than she was, not that Sabrina minded. At least the legacy would still live on through one of the sisters, right?

Anyway, she had woken up to the usual weird breakfast along with some studying and training with Granny Relda. Than, later in the afternoon, she had some free time. Daphne wanted to go walking, so they did. They went farther than they normally do, walking along the Hudson until they reached the magical boundaries surrounding Ferry Port Landing, but something seemed off about the forest. Like there was some kind of disturbance. Sabrina paused to look around, but when she didn't find anything majorly noticeable, she continued the walk.

Suddenly, a loud squeal that Sabrina knew belonged to Daphne rang out through the forest and Sabrina ran to the noise, wondering what was going on with her sister. What she found was unexpected to say the least.

A winged horse sat in the middle of a clearing, its wings spread out over the ground. It almost looked like the horse was trying to protect something. Daphne stood by the edge of the clearing, biting her mouth as she tried to control herself from gushing about the pegasus in the woods. Sabrina went up and stood protectively in front of her little sister, she had had less than welcoming experiences with animals she didn't recognize, and she would not take chances with the pegasus. In her mind, the pegasus looked hostile, as if it were threatening her, daring her to approach.

Daphne, however, had a different view. She stepped around Sabrina, ignoring the warnings thrown at her as she carefully approached the pegasus. Her mind was running through all the things she could do with her very own flying horse. As she walked, though, she couldn't help but notice how the pegasus slowly closed its wings more tightly against whatever it was resting over. Daphne looked at the wings carefully, looking for any tall tale signs of a wound.

"What's wrong? Are you hurt?" Daphne asked carefully.

The Pegasus seemed to snort at that, but stared at the little girl calculatingly. It seemed to be weighing its options before the horse nodded at Daphne.

Seeing this as an encouragement, Daphne continued to walk forward until the Pegasus unfurled one of it's wings showing what was underneath. Sabrina gasped as she took in the sight of a fourteen-year-old teenage boy laying on the ground, unconscious.

A/N: So that was the prologue... Yay? If you happen to read my other story, I really need to just sit down and work on the next chapter. I know the plot line is somewhere there. As for this one, I'm sorry if it was bad. I needed to get this idea out of my head. I don't know what points in the story I want the characters to be in. Help decide? I'll see when I can update. Until then, BYE!
