I do not own Percy Jackson or Poseidon and Nike's Ocs. Sorry about any typos, badly worded sentences or just awful grammar mistakes, my auto correct is out to kill me.
Prologue... Nico Di Angelo...
"Okay Luna, you win! I give up!" I sighed and flopped onto a casino sofa. Tiny little footsteps ran down the casino steps. A little girl appeared at my feet seconds later. "Luna the champion of hide and seek wins again!" She squealed. Bianca suddenly walked over and grabbed the little girl, tickling her so she squealed. "N-No! Luna doesn't like tickle time!" She struggled in Bianca's arms.
Bianca sat on the sofa next to me, Luna on her lap. She whipped out a brush from under her green hat. "Luna, your hair is sticking up all over the place!" She exclaimed, tackling the younger girl's locks with the brush. Pouting, Luna struggled as Bianca tied her hair into two separate pigtails, one on either side of her head. "See how nice you look with that pretty blonde hair of yours brushed?" Bianca smiled, bouncing the girl on her knee.
Luna couldn't of been older than two, easily the youngest person (not to mention the strangest looking with her blue-silver eyes) at that casino. She also had this weird habit of talking about her self in the third person. She had been at the casino longer than anyone else, in fact she told us about how she remembers it before it was a casino... Not that anyone believes her...
"Luna, where's Phoebe?" Bianca asked after a few minutes of bouncing her on her knee. Luna shrugged. "Luna does not know." She replied, tugging on one of her tiny pigtails. Bianca sighed. "Nom." A little voice screamed just before something like a vice clamped down on my leg. "Oh! There's Phoebe!" Luna giggled, pointing to her older twin sister.
"Gerroff me..." I yelled, shaking my leg free of the girl's jaw. As soon as she let go, she collapsed into a fit of laughter. She was clutching her potted plant that she was never without. Suddenly, a scratchy voice echoed through the casino. "Can Phoebe and Luna from room 1142 please meet their father at the front desk please? Thank you. Please enjoy the rest of our amazing aspects if you come back! Have a good day." It announced. Phoebe and Luna shared a puzzled look. Then they both looked in the direction of the front desk warily. "Who is 'father'...?" They asked in unison, confused.
A smiled crossed Bianca's face. "A father is some one who is your parent. For instance, Nico and I have a father called-" Bianca's voice cracked. We didn't know who we were before the casino, not even a tiny thing like our father's face or name. I cleared my throat. "Why don't you go and meet your daddy already? He obviously wants to see you!" I plastered a fake grin on my face. The twins nodded, not bothering to hide the fear in their chubby little faces. "Okay..." Phoebe sighed, and began tugging her sister along behind her towards the suddenly sinister front desk. Luna looked like she was on the verge of crying. "Bye bye Nico and Bianca.." Luna mumbled.
After that, we didn't see them again within the casino. Not even after we left about an hour later.
