Percy Jackson's Twin Sister

Another Sister?

The ship was swerving violently. Waves the size of skyscrapers were crashing at the side of the ship. Lightning flashes all around and the clouds were so dark you couldn't tell if it was day or night.

The crew was trying to fight with little success. Percy and I were the only ones having any luck. Every time a wave hit we pushed the ship in the opposite direction to stable it up. But honestly I was getting exhausted fighting this storm already. This took a little of power.

Jason came to our side. I didn't give him much of a recognition. I couldn't break focus but Percy nodded at him.

My twin and I were soaked. We didn't have time to concentrate on keeping ourselves dry.

There was something at the bottom making this storm. Something powerful. Percy yells something to Jason. Percy had already kind of gotten the point across that him and I were going down there and I guess Jason now too.

Percy grabs my hand and we runs to the edge taking a leap in. As soon as I hit the water it gets quieter. It wasn't much better down here though.

"You have a plan right?" I ask.

"Partially. Something is making this storm down there. You know that," he says.

I nod. I see Jason come down on a cyclone if wind her must have harnessed from the storm. His face said this was weird gif him. Although not everyone spends a lot of time at the bottom of the ocean I guess.

"Hey," Percy says.

"What's going on?" Jason asks.

Percy points to a void where the light flashes had come from. There was something powerful down there.

A shaft if green light swept through the darkness.

"Something's down there," I say, "stirring up that storm."

Percy looks at Jason's tornado, "Nice outfit."

"I have no idea how I'm doing this," Jason says.

"Okay," says Percy, "just don't get knocked unconscious."

"Shut up Jackson," says Jason.

"Let's see what's down there,"I say.

We sink down to the point we have to use our blades to see. Ever so often the green light shoots upwards.

When we reach the bottom patches if algae glows illuminating a palace.

"Atlantis?" Jason asks.

"That's a myth," I say.

"Uh.... Don't we deal in myths?" Asks Jason.

"Those are fake myths... ours are real myths," I say.

"I thought you were the smart twin," Jason jokes.

"Shut up Grace," I say.

We float through the broken dome and down into the shadows.

"This place seems familiar," says Percy.

I look around, "It's kind of like- "

I didn't get to finish that thought. A green flash happens directly below us. We all drop like stone, touching down on a marble floor. We were talking alone either.

Standing before us was a twenty foot tall woman in a flowing green dress. Her skin was luminous white like the algae.  Her hair swayed and glow. Her hand rested on a wheel made of polished green metal.

The woman turns the disk and green light shoots upward shaking the old palace.

"You're making the storm!" Says Jason.

"Indeed I am," the women says.

"Ok I'll bite," says Percy, "Who are you, and what do you want?"

The women turns to us. She seems to be studying me and Percy, "I am your sister, Perseus Jackson. And I wanted to meet you before yo died."

Percy looks at me like he was questioning if it was true. Like he couldn't have more than one sister.
