"Percy.. Tyson, im gonna need you for a mintue or two of your time"
They both looked at each other and proceeded to stand up off the benches that they were sat on.
Walking alongside Mr D with his centaur like body and his hooves put off Tyson a little bit.
He was still getting used to being in Camp Half-blood and being next to other creatures of the Greek world.
"Is there something wrong, Mr D?", said Percy curiously.
He trotted along infront of them. This was going to be a tough situation for them to handle and he knew it.
"You havent done anything wrong Percy, theres just something you need to see", he lead them down the dirt path towards the water front.
That was where Percy and Tysons cabin was, Poseidon himself built it for them on the water so they knew that there father wasnt that fair away.
Percy walked onto the planks with Tyson following behind only two steps. There was a figure of a girl in the doorway, she had long black hair, pale skin and when she turned around to face them she had sea green eyes.
"Percy, Tyson.. this is your half sister..", Mr D stood next to her.
Tyson walked forward to examine her closer, and then looked at Percy.
"Who are you?", Percy said.
"Elana.. Daughter of Poseidon".
Tyson just smiled at her and embaced her for a hug but she pushed him away. Cyclops she wasnt used to. But where she came from in Olympius all the cyclops' were evil or used as slaves.
"Can you help me get back to Olympius to be with father again?", she said softly.
He looked confused at her, she was with their dad all this time but how did she end up in Camp Half-blood?
Thats what confused him so much.
Of course, Poseidon wouldnt leave his daughter here unless something was happening back in Olympuis between the gods and he sent her here for protection.
"Youve been with dad?", Percy looked at her.
"He brought me up.. alongside Zeus of course, but mostly dad".
The 3 half siblings looked at each other, they all were different, but Percy was more like Elana with the hair and eyes which must be a triat off Poseidon.
But Percy, Tyson and Elana had 1 thing in common.. that was they were all children of Poseidon.
