A/N: I do not own Percy Jackson and the Olympians. I do own this story.
Prologue
Persephone's Garden, Underworld
A young, living, demigod girl was hiding in the bushes watching her mistress turn her stepson into a dandelion. As Persephone left, she saw the dandelion change back to a demigod.
The stepson's name was Nico: age of 13, son of Hades and Maria di Angelo.
Days later Nico di Angelo returned, accompanied by a male and a female. They appeared while she was in the garden. Her mistress, upon spotting the visitors, hurriedly told her to hide. She knew of her mistress' plan.
A sudden flurry of voices was heard. But only one was heard clearly.
"You, girl, will kill them. It is your destiny." A voice said.
"Why?" The girl whispered.
"Do it and you shall have everything your heart desires." The girl searched for the speaker. The voice seemed to come from nowhere and everywhere.
"Once you have done what I said, my servant will come for you. Question him if you must."
"Anything I want? Like freedom?"
"Yes, yes. But first you must help me. Help me defeat the cruel gods. If you don't think they are cruel then think of your curse and Hades cruelty. Isn't that cruel? So serve me."
The voice waned. Finally, only an echo of serve me could be heard.
She was left there behind the bushes, pondering the voice's commands. Faintly, she heard her mistress summon her. She scurried out from her hole and kneeled on the feet of the goddess.
"Mistress?" She bowed.
"You must help Percy Jackson, son of Poseidon, and Thalia Grace, daughter of Zeus, to retrieve you master's sword." She conveniently left out master Hades' son.
Who must I follow?
"Follow me. Remember anything you want."
"I'm sorry who ever you are but for this one quest I must help them after that I must first test your theory about how they are all cruel."
A roar of defeat washed over the entire Underworld, but she was already gone.
The first time the girl came of use was when they passed a group of war demons. She pulled on her necklace and it became a sword. She saw the others do the same. She made contact with Nico and started to make undead soldiers come out and fight the demons.
"Whatever you're doing Nico continue on doing it!" The boy named Percy said.
The fight started she hacked away at two demons then sliced the demon to her left. Then she touched Thalia's shoulder. She started throwing lightning bolts like Thalia.
The fight was done. Even though Percy got wounded but they continued on their journey. Soon he had to lift the whole river Lethe and of course the girl helped him. She helped them all the way without them noticing.
Her mistress called her and she returned.
This was her chance to test the voice's theory.
A short conversation ensued.
"You must go back to your room before they return!"
"But mistress let me go back to the upper world with them! I need to see the light of the sun the beautiful, soft grass and the colorful flowers like those you tend when you're with your mother!"
"You cannot they will claim you. They will never let you go back here again; I cannot loose my only living helper, can I?"
"No mistress, but I promise that I will come back. I will tend the garden will you again? Please just let me go this once."
"No"
And with that final word the conversation ended and she knew the answer to the voice.
Yes, they were all cruel. For that no pertained to a lot of things.
A/N: SUSPENSE! Who is her godly parent? How can she both control the dead, lightning and the water? Why is a living demigod in the Underworld, helping tend to Persephone's garden? So many questions to be answered so if you want to know the answers, REVIEW! Oh and the necklace she owns produces the Mist making her look anyway she wants to look like or camouflages her.
