3. Switching POV's

That's about it! And now enjoy my fanfic: The Greeks and the Brits.

Chapter 1

Leann's POV

I sat in the Poseidon cabin shaking my head in disbelief at the news Chiron just told the camp. Another camper has left us to join the Titan army.

That's three so far and all of them have been unclaimed campers in the Hermes cabin. I sighed as Percy walked in.

"This is so frustrating!" he said, shaking his head.

He sat down next to me and sighed. "I don't know what we're gonna do."

I smiled at him encouragingly "We're gonna kick some Titan butt!" I said happily. He smiled back

"Yeah, I guess" he got up. "C'mon sis" he said "We're gonna miss sword practice"

I stood up "And this time I will beat you"

We ran all the way to the Sword Arena. "So? Did you finally name your sword?" he said sarcastically.

"Yes I did! I named it τρίαινα" he nodded approvingly.

"Trident in English… I like it!" I took out my dagger and pressed the little button on the side with a tiny trident etched into it. It extended into a sword.

"The inspiration for the name came from the 'extend' button"

"Before we train, I have something to give you" said Percy. He handed me a golden charm bracelet. "Happy twelfth birthday sis! You can put as many charms as you want on that bracelet." he said. My birthday! I forgot! I put the bracelet on and counted to three. We began battling.

Eventually I let instinct take over. After about five minutes I had him pinned, sword point at his throat.

"Finally! I beat you!" I said happily.

I helped him up and looked around the arena. It was soaking wet and I noticed the both coolers of water had exploded, along with the water bottle Grover was holding. I hadn't notice him standing there until now.

"Oops" Percy and I said at the same time.

I laughed and we both willed the water over to the lake. "Leann" said Grover "Chiron needs you."

"Okay" I said happily. "Race you to the big house" I said to Percy.

"You're on" he said, and we took off.

We tied. Chiron, in wheelchair form, was sitting on the porch. "Come inside" he said.

He went in and Percy, Grover, and I followed. Waiting for us in the room was a beautiful woman with long black hair and light skin.

She radiated power. Grover bowed at once "Lady Hecate" Percy and I followed his example.

"Lady Hecate, what brings us the privilege of your presence?"

"Why are you not on the Titan's side like most other minor gods and goddesses?" said Percy very abruptly.

Grover and I gasped at the same time.

Hecate turned her kind gaze on Percy "I may not be Athena" she started "But I am smart. I know that if the Titans take power, every god will fade. Not even a Titan can stop that. Every god on the Titan's side would fade too." She said. Percy nodded.

Hecate turned to me. "Leann, you may not be the child of the great prophecy." I looked at my feet at that comment "But!" she continued. "I do have a mission for you. One of the most important ones." I cocked my head, curious. "There is another world you don't know of. A world beyond mortals and demigods. It is the world of witches and wizards." My mouth fell open and Percy and Grover gasped. "What!" I said a little too loudly. "Yes, I know it is hard to believe." She said gently "But they do trace back to me. When it started, I blessed a few mortals that were scattered all over the world, or what country's there were at the time, with magic. These few began the wizard race. There are three groups of wizards. Pure-bloods, half-bloods, and mortal born, which they know as muggle-born- muggle means non magical people- or mudblood, which is the very unkind term for mortal-born wizards. Pure-bloods are wizards born from other wizards. Half-bloods are born from a wizard and a mortal, and mortal-borns are regular mortals that I have blessed."

"There is one wizard school, the first and the best wizard school, called Hogwarts School of Witchcraft and Wizardry. And you Leann, are going to go to that school, and be a student there to gain the trust of the witches and wizards and have them help you fight Kronos!" she finished "WHAT!" I yelled.
