Yes, this is going to be a multi-chapter fic. It's a random theory I've had that came out of no where. Literally, I don't know why I thought of it, but I say it, therefore it goes. It doesn't really connect to anything in the book, but I had a really weird dream one night...Yeah, please just try it. I own nothing!

Helen woke up with a start. Nightmares, creatures from beyond Tartarus.

You may be wondering who this 'Helen' person is. Well...

She's Helen Jackson, the eldest child of Poseidon and Sally Jackson. She's not as famous as her little brother, Perseus Jackson, Percy for short, but Helen called him Perseus to irk him.

Then he disappeared. Out of the blue, her stream of pride gone, her brother was taken from the Jackson household before he was one year old.

Where? She doesn't know. How? Helen doesn't know that either. Who? Another unanswered question. Why? She suspects it is because he's a child of the Big Three. What? Helen's brain doesn't even know how to answer that question. When? Before he was one. Where? If Helen knew where he was, he would be back here already.

Her thoughts were quickly interrupted.

"Helen?" that was the voice of her grieving mother, Sally Jackson.

Sally was an unmarried woman, the sweetheart of Poseidon. She had not seen her son for six years, and her lover longer than that.

Helen knewhat you are going to ask: yes, she knows she's a demigod, but where's the fun in staying at camp? There is more adventure in the outside world anyway.

"Helen," Sally said again, much more firm.

"What? Sorry, ADHD." the black haired girl explained.

The older woman rolled her eyes. "Sometimes I think you use that only as an excuse,"

"Get to the point,"

"Chiron wants you to go on a quest," Sally started.

"Really? Who? What? When? Where? Why? How?" Helen stood up, bombarding her mother with questions.

"He want's you to find Percy,"

"Why would he want me to do that?" the daughter of the sea raised an eyebrow. "Surely there are more experienced fighters than I am. Take Luke for example."

"But Luke's a son of Hermes, sweetie," her mother sighed, "A child of Poseidon would most likely be able to track him down."

"Do I have any partners?" Helen almost pleaded.

"I can't go with you, but I can help you pinpoint a location," Sally smiled.

"Do you have any ideas?" the younger female inquired.

"One,"

"What is it?" Helen demanded.

"The Middle World," Sally winced.

"What's that?" the daughter of Poseidon was slow today.

"It's a world in between the one we stand on and the Underworld. Every generation, demigods are chosen specifically to fight against each other down there. Demigods versus demigods. There is no distinguishing mark of who's on what side. It's not Roman versus Greek, it's just, who you are chosen as. The Middle World takes the chosen ones closely following their birth in order to bring them up fighting," Sally looked worried. "Helen, you have to go in there."

"What happens if I refuse?" Helen asked.

"I'd be left with no children. The gods would vaporize you," her mother answered simply.

"How do I get into this Middle World?" the daughter of the sea inquired.

"That's the easy part," Sally smiled reassuringly. "The hard part is getting Percy to trust you and to come back to the surface world. In order to enter the Middle World, you must slice this in half with your weapon."

Her mother put a square cube on the table.

"Where did you even get that?" Helen asked.

"Poseidon didn't leave me defenseless against the odds of fate," Sally said quickly.

"All right," the demigod took out a flash drive.

Uncapping the flash drive, a tiny dagger appeared. Where the actual plug was supposed to be. Don't get it mixed up with a real flash drive!

Helen stabbed the cube before dissolving in a shower of gold.

Review! Tell me what you think! I'm still going to continue this even if no one likes it because I just need to get this down.
