A human ear can't hear a ducks echo without a machine. No one knows why.
Percy Jackson walked into the training arena 5 minutes before his private training session to stretch and warm up. About 3 minutes into his warm up, a man in a wheelchair and a boy about maybe 15 or 16 came into the arena.
"Ah, you must be young Perseus," said the man in the wheelchair.
"I go by Percy, sir."
"My mistake. I am Chiron and this is Walter Danielson, we'll be helping you train today," Percy stuck his hand out, and Walter shook it firmly.
"Chiron, as in the Greek trainer of heroes?" Percy inquired
Chiron's eyes held amusement and as did Walters, "Yes, exactly like that. Now. Let's begin. First, I want you and Walter sparring in hand to hand combat."
Percy took a quick glance at Walter to study how he might fight. He was roughly 5'8" or 5'9" with sandy blonde hair, brown eyes and sharp features. He looked pretty lean, but looked as if he was faster and wouldn't use brute force.
Walter and Percy put up a fighting stance and waited for the other to make the first move. Percy noticed that, by waiting for Percy to start, that he could tell what kind of fighter he was. Percy started with quick kick to the chest, which surprised Walter, but he blocked it anyway. They exchanged a few punches and kicks until Percy jumped far left, making Walter take a quick step over, and dropped to the ground and swung his leg around in order to take Walters feet out from under him. Walter looked surprised to be beaten but accepted Percy's hand, and got pulled up.
Chiron rolled on over smiling hugely, "I see what you did there boy. You saw how Walter was quicker, and trapped him using it. Now, when you were…"
The rest of practice was all on technique, and then it was over. The next couple of days were a bit strange to Percy. The style of fighting Chiron and Walter used felt more regular to him, and they used more swords and knifes than he thought necessary, but it did feel natural, and he really caught on easily to the many uses and tricks of both and a knife and a sword, and how to fight against someone with a knife when he was a sword and vise versa.
A week after Chiron first showed up, Percy strode into the arena, but they weren't here like normal. He thought nothing of it, but 15 minutes later, a man in a suit with a briefcase walked in and approached him.
"Excuse me, are you Perseus Jackson?"
Percy studied him as he replied uneasily, "Yes, can I help you?"
The man chuckled, "Oh Perseus, you can help me in ways you do not know of."
Percy was a little nervous, "Do you want to see Captain Morris, because I could show you to-"
"No, Perseus, I'm here to see you. Now, if you'll just return what you've taken, we can just go on our merry ways."
Percy stiffened, "Am I being accused of stealing? I swear I have not taken anything. What do you think I stole?"
The man pursed his lips, "I see you want to make this more difficult then it needs to be. Ah well, I tried." Then he grew two sized and turned into a giant bat with razor sharp teeth and claws. "RETURN THE BOLT OR SUFFER."
Percy's eyes widened as he stuttered "Wha-what! What are you! Who are-are you! What?"
Just then, Chiron and Walter ran in. "Percy! Catch!" A small object was thrown his way.
"A pen? Chiron, What-" The bat/lawyer swooped down and picked up Percy and just before crashing into the wall, Chiron yelled, "Uncap the pen!"
Sudden pain shot through Percy's body as he crashed through the wall and out into the sun, and as soon as his vision came back, he saw Manhattan below him. He remembered Chiron's words. Soon he held a sword in his hand, much like the ones Chiron taught him to use. Percy plunged the sword over his head and into the monster.
Now, Percy just acted on instinct, not realizing that the monster would dissolve and he would be hurtling towards Central Park's lake at a million miles per hour. Ah shit.
