Edited version: I took out the prologue thinking it just wasn't Artemis. I bet none of you really cared about how Artemis met the mortal and such. Just R&R when done.
Nico was sitting outside the Big House. He was bored and didn't want to stay in the Hades cabin. Percy was busy practicing his sword-fighting, Annabeth was reading, and Grover was searching for another demigod. He was almost napping when he suddenly heard shouting. He looked up to see Grover running down Half-Blood Hill with an unconscious girl in his arms. She got up and ran to help him. Up close, the girl was about thirteen with wavy auburn hair and a celestial bronze knife sitting on her chest. She was bleeding but it was nothing some ambrosia and nectar can't do.
"Grover, what happened?" Nico demanded.
"We were attacked by a monster. The Nemean Lion. She defeated it, but she was still knocked out."
Nico brushed away some of his black hair away from his eyes and said, "Give her to me. I'll take her to the infirmary."
Grover handed the girl to Nico and headed towards the infirmary. She looked familiar but he never met her. As he laid her down on a bed, she began to talk in her sleep.
"Alex."
As Nico took some nectar, he couldn't help wonder who Alex was. Nico began to slowly spoon-feed her some nectar. Soon, her eyes opened showing a silvery yellow color. Her eyes were breath-taking, a color like silver but with traces of light gold. Nico remembered now. When he was ten, he met a goddess with auburn hair and strange eyes the color of the moon.
Artemis.
But it's impossible Nico thought. Artemis was a maiden and never had children. Could it be that this girl was her daughter?
The girl spoke softly saying, "Where am I?"
Nico gave her a small smile and said, "In the infirmary. You were unconscious for a while."
"Grover-"
"Is fine. Now you might wanna rest."
The girl seemed glad to rest then she said, "I'm Selene."
"I'm Nico."
Soon, Selene was fast asleep and Nico left her there.
Kinda short, but I'll try to update more but I'll need 5 reviews :)
