Poseida and Percy should really stop hanging around each other -Tartarus
Percy stood on the cliff with his sister and remembered the first time they met. It was short and awkward and neither of them knew what they were doing.
Flashback
Perseus walked behind his father as the ruler told him how they were going to rule the world [Seriously people, get original!].
"Then we will-" He was interrupted by someone falling on him.
"So we meet again" He could hear the panic in her voice as he studied her. She looked like him, human skin and nothing else, no mutations or animal parts.
"I thought you would be gone for good you meddling little girl!" His father bellowed. The girl's eyes widened and she ran, grabbing his arm in the process. They jumped off one of the many cliffs, the only thing saving them from falling to their deaths was Percy.
"Are you mad? Wait, everyone here is, but that's not my point. Who are you? Why did you bring us off that cliff? Lastly, why did you bring me?"
"I'm sooo sorry," She mocked, her long black hair falling sideways as the earth stabilized them once again. "I didn't mean to come back here." She looked at the chaos under them, her shoulder shaking slightly. "As for the questions, my name is Poseida, I panicked and you looked familiar and again, I was panicked. It's not everyday you get dragged into your worst nightmare again." She glared at the darkness, anger resurfacing.
It's not her fault her father is an idiot and hates her. Well, the last part is her fault, but whatever. She didn't ask for this at all, especially not to be back in a place like this now that she knew what the upper world looked and felt like. She missed the sun glaring at her back and giving her sunburns, wrestling her cousins in the grass of the fields and not having to look behind your back every second because you have a gut feeling something will happen if you don't.
"Woah, calm down" Percy stumbled as the earth beneath them shook. Poseida raised her eyebrow as the earth shook harder, the water in it rising and swirling around her.
"Who are you anyway? Why were you with Tartarus? Are you on his side or the monsters?" Percy felt himself start to suffocate when he looked into her anger-filled eyes without flinching. He tried to look away, but the hurricane in them kept him from doing so. He felt freezing water wrap around his body, like Kampe's wip when someone displeased her/when the Cyclops acted up.
"My name is Percy, he is my father, and I don't know?" He managed to get out. The water let him go and soaked back into the dry earth as Poseida narrowed her eyes, but Percy was released from the hurricane in her eyes. "Do you want to go back up? It's kinda awkward here" She shrugged and looked down. "I'm going to have to shift your center of gravity a few times." Without waiting for her response, he changed their center of gravity to the way they were standing.
Shifting your actual center of gravity was not fun at all. It felt worse than that one time Poseida fell into the River Styx during a battle. Now, that was definitely not fun at all.
"Ugh" She almost puked and steadied herself, reaching for the water around her to steady herself, thanking Chaos for the air to be really humid in the pit. It was the one and only time she was going to thank him instead of curse him and the fates, so don't go looking for more. She looked around where she fell and looked for the scythe she managed to grab as she was thrown and smirked at the hell she knew Kronos would pay. "Where is your father now?"
"Uh, good question, probably killing some monsters judging by how he looked when you fell on him. Where did you come from anyway?"
"The upper world. I'm guessing you're my little brother from mom's side. She was talking about a Perseus, and I'm guessing Percy is short for that?" He winced.
"Don't say my full name, it's reserved for people trying to kill me."
"Oh course it is" She looked around to see where she was. The heart, yay, that was always so fun to get out of. So much fun.
"And, you're my sister?"
"Don't look so disgusted"
"I'm not, you're just so weird."
"Says the one who can shift someone's center of gravity." Her stance reminded me of Kelli.
"And you fell from the roof!"
"Yeah, so we're both weird, that settles it?" She leaned on a wall and took out one of her knives.
"Where did you get that!?"
"So unobservant, and you think you can survive here?" She laughed, the sound on the edge of insanity that unnerved even the best of people. Percy looked a bit disturbed and backed a few feet away as Poseida hoisted herself up to sit on a ledge, leaving her feet dangling.
"I don't think I'm going to recover from that sound"
"Don't worry, nobody does. Now, let's stop being boring and walk away from this... place. Could you even call it a place?" She asked and got down, not a minute after she got up.
"Sure"
Flashback End
Poseida was awesome and fierce, never ever giving up to the enemy and protecting him with her life and more. He would never trade her for anyone. Often, Percy would wonder if they would ever go to the upper world. Poseida said it was awesome, but why had yet to find a way out.
Percy jumped when he heard his father shout his name in rage. Poseida winced next to him and gripped her scythe harder, ready to use it if necessary.
"Why do you keep on hanging out with her"
"Because she's my sister? Why else?"
"And you even talk back. That's it, you are not allowed free reign here and from now on, you will spend your time learning how to become my heir."
"You sound so much like a disney villain." Poseida muttered and Percy ignored her, used to the comments that made no sense at all. Tartarus took a minute to stare at her and then turned back to what he was doing.
"Come on" Poseida snickered sinisterly and stared at something, her eyes going dark.
"You really that's actually going to happen?" She asked, tossing her weapon between her hands and somehow made Tartarus feel small. He squared his shoulders and turned to face the nuisance.
"Yes, I am a primordial, you are mere Titans."
"And you're a mere speck of dust compared to the universe itself." She spread her senses past the planet's atmosphere and to the other planets. Percy did the same and felt the mass and gravity of the other planets as he smirked at his father.
"So? You are an even smaller speck"
"Big things come in small packages" She created an illusion on him and grabbed Percy. They climbed the cliffs for the thousandth time.
"How long do we have?" Percy put his own on him.
"With yours? A few hours" Percy cursed, that wasn't enough time to try and find a way out.
"Why are you cursing, that's enough time if you count to the millisecond" She climbed faster and decreased the gravity on herself to help her get up faster, Percy did the same.
"Let me guess, you know a way out?"
"Yeah, I've know ways out since I was first here"
"And you didn't tell me? Why?"
"Things" Now it was useless for him to try and get something out of her. She was as tightlipped as a wall when like this and tended to talk in confusing riddles that made Percy question if everything he knew about the basics of life was real (which was not fun, believe him).
"Where is it?"
"We climb all the cliffs and at the very top there is a small passage at the top we run across and then move the rock at the end of a tunnel across the clearing in the middle" That made no sense, but whatever, Percy trusted her.
Once doing exactly that (climbing 3 sets of cliffs, climb another small passage, then there was a big clearing with a tunnel angled up with a huge rock at the end, if you were wondering what Poseida said), they got to a bright place that looked blue before he shut his eyes.
"Welcome to the upper world" He could hear the smile in her voice then slight sadness at the end as she seemed to look at something. "You good?"
"Light hurts" She rolled her eyes and placed a hand over his eyes, her powers taking over and forcing his eyes to get used to the light faster. "Thanks, what's happening"
"I'm guessing a war? Someone's fighting my father, instant respect to them." Percy could agree with her, but was surprised someone gained her respect so quickly, but then again, Poseida hated her father more than she hated Tartarus.
"Are we going to help?"
She snorted, "Of course." And then ran off to join the side fighting the titans.
