Ryan Monte was an English teacher at Eston Middle School. During summer break one day, he was planning out the next year's curriculum at his house when he looked outside at the neighborhood and saw a strangely-clothed woman taking a stroll through the neighborhood. He was unable to look away. He saw all his deepest memories in her, somehow. She looked surprisingly like his late wife, Isabel Monte. He knew it was not her - Isabel's nose was sharper, her eyes bluer - but still wanted to talk to this woman. He thought he had known her all his life, as she was (in his mind) a fellow English teacher, only for seventh grade. They had flirted in the teachers' lounge sometimes, and Ryan just wanted to greet her.
He thought her name was Emily Carter. He greeted her, and "Emily" greeted him back. Blake suddenly felt a surge of love for Emily (actually it was Mnemosyne, making Ryan "remember" he had a crush on "Emily") and, since they were so close to his house, why not rendezvous? So they made their way to the bedroom. It was nighttime, though, and "Emily" crept out of the house, making Ryan forget everything about her. However, she implanted some memories in his brain so that he wouldn't be too surprised when a baby appeared on his doorstep, four months later.
This made perfect sense to Ryan once it happened, even though it shouldn't have. Mnemosyne implanted memories of someone telling him about Camp Half-Blood. Ryan understood, and went on with life as usual, caring for the kid he named Blake and going to his PeeWee games. For a demigod, Blake had a pretty normal childhood. He liked football and baseball, thick books, and his dad. Simple. Sometimes he was teased for liking such big books, like Harry Potter, in first grade. He remembered every hurtful comment, which pretty much sucked for him. He never retaliated, just let the bullies tease him endlessly throughout elementary school and the beginning of middle school.
Little did he know that a satyr had come to get him. However, the satyr was doubting Blake's demigod-ness because of the lack of monster attacks.... Still, the satyr stuck to Blake just in case. He just didn't want to accidentally bring perhaps a clear-sighted mortal to camp.
Just when he thought the bullies were the worst problem in his life, at age thirteen, a whole flock of seemingly metallic birds attacked him outside. Blake hopelessly tried to fend them off, but the satyr came and did it himself by clashing two rocks together nearby. In the time it took, though, the satyr was pecked to death. Camp Half-Blood didn't hear about this incident until later, however. Plenty enough time for Blake to turn fourteen and have a harpy attack him. Fortunately, he had savaged the late satyr's sword. He sliced at the harpy's wing, making it fall to the ground. The harpy scratched a claw/finger across Blake's leg, and he cursed, but made several attempts to pierce the sword in the harpy's heart (as it was heavy for him) before finally managing it, on accident.
However, he had a MORTAL father. He did not know that his father knew about everything, and so discarded the sword, at his own risk (he wasn't very bright, despite the books). He didn't want any questions, because he thought they would worry his father and he wouldn't have answers anyway.
Finally, a satyr came for him. Blake stayed safe for another almost two years, right before his sixteenth birthday. Then a hellhound leaped at him from the bushes at school. The Mist made all the mortals think it was a loose poodle, and no one paid attention. The satyr did, though, and slashed at the hellhound's body, dissolving it into dust. He offered to take Blake to camp, and Blake agreed, happy for once to be safe.
When the satyr explained about him being a demigod, however, Blake couldn't help thinking, Why didn't my godly parent help me kill the monsters, then? Why didn't they help? Do they even keep in touch with their children? Do they care? He shook away those thoughts at first and journeyed the long way to Camp Half-Blood, turning sixteen along the way.
Finally, they reached camp. Blake was introduced and was overwhelmed by the vastness of it, but the satyr, Thomas, told him he needed a weapon. When they arrived at the armory, first Blake looked at the swords. Then he saw a bow and arrow out of the corner of his eye, and picked it up. He decided to take a walk out of camp borders, in the town, just to breathe in some non-demigod fumes for a while. Some demigods, he could swear, should seriously take a shower.
That was when he saw an odd boy, with a sword, walking around the town. Blake was certain he was a demigod because of the sword, but didn't know who he was. He casually asked the boy where he was staying. The boy eyed Blake's bow and arrow, and replied, "The Broken Covenant, of course. Aren't you one of the god's slaves? Don't you know better?" Blake asked him what he meant, and the boy explained about the BC and its factions. The boy was from Veritum Unitum, and rambled about how it was the best faction. Blake realized that his beliefs about the gods matched Veritum Unitum's exactly.
The boy welcomed Blake to the BC, and Blake happily obliged.
