Okay, here is my very first Percy Jackson fanfiction! I'd ask you guys to cut me some slack, but that's probably a little obnoxious. So, let me know if I need to correct anything, be it spelling, grammar, or a character's personality. Enjoy! :)

Nico di Angelo ducked as the huge snake head lunged at him. It barely missed and struck an oak tree. Nico swung his black Stygian iron sword to cut off the monster's head. The creature dodged easily with graceful but deadly speed.

The son of Hades had been fighting the beast for the last fifteen minutes, and neither one had come close to delivering a killing blow. He was getting tired, and on top of that, he had no clue what this monster was.

It was a serpent, maybe fifteen feet from head to tail. A poisonous snake head was attached to either end, and in the middle of its body it had dragon's feet and legs. Nico didn't know what its name was; it certainly did not remind him of any Greek monster he knew of.

He hoped Annabeth knew. She was a child of Athena, her mind full of genius ideas and knowledge, and she was probably smarter than all the campers in Cabin 6. She knew all there was to know about the Greek myths, the gods, and monsters. If she would just hurry up, she might be able to give him advice on how to kill this she could show up with reinforcements, that would be even better.

"Braccas meas vescimini!"

Annabeth Chase burst through the trees, followed by Hazel Levesque, his half-sister, Frank Zhang, Percy Jackson (who had yelled the battle cry; what it meant, Nico didn't want to know), and Piper McLean.

Finally, Nico thought, not moving his eyes away from the snake beast.

"What the heck is that?" Percy yelled, uncapping Riptide, his ballpoint pen that could magically transform into a Celestial bronze sword. Piper, Hazel, and Annabeth unsheathed their blades, and Frank notched an arrow to his bow, though it was hard for him to aim for a snake head, since they both constantly swayed and bobbed.

When Annabeth didn't spout any knowledge about the monster, Nico got a sick feeling in his stomach. This was not good.

He quickly shook himself out of it. Fine, he thought. We'll just have to deal with this thing on our own. Gripping the hilt of his sword even tighter, he charged the beast.
Hazel yelled something in Latin and surged forward, the girls and Percy right behind her.

While the demigods together definitely stood a better chance against this unknown monster, its serpent heads and swiftness still made it difficult to land a fatal blow. Piper used her charmspeak to keep both heads distracted while Annabeth tried to creep up on it and stab it, Frank and Percy backing her in case things went wrong.

Things went wrong indeed.

The second Annabeth's blade sunk into the serpent's middle, Piper's charmspeak wore off. Nico guessed the pain woke it right up. The monster hissed in pain and spat poison wildly, but it didn't disintegrate into dust like monsters normally did.

Both serpent ends swung their heads around, searching for the one who stabbed it. All four sharp eyes fixed on one demigod: Hazel. Baring sharp fangs, both heads lunged.

Time slowed down for Nico, like Kronos, the Titan of time, was standing in the middle of the forest with them. Nico's body moved on its own, as if his mind no longer controlled its actions. He sprinted towards his sister and pushed off the ground, shoving her out of the way.

And then, time resumed at a normal pace. Hazel was covered in grass stains and dirt, but unharmed. Her brother wasn't so lucky.

Nico felt like his leg, then his entire body, had been bathed in acid fire. The pain was unlike anything he'd ever felt. He simply couldn't take it. He blacked out.

I'd appreciate it if you'd Review, but you don't have to. Honestly, I'm really happy you decided to check out my fanfic. So, thanks! :)
