A Drop in the Ocean

Chapter One

Not Again

"What do you mean it's missing?!" Percy barely heard herself exclaim, shooting up to her feet, the chair making a sharp noise as it was pushed back. Everyone else at the table winced at the volume of her voice, Triton rubbing the back of his neck with a sigh, mentally cursing the mortals and their loudness.

It was bad enough that now, when his father's trident was missing, all the responsibility about the ocean fell on his shoulders, but he also had to ask his half sister to help him search. As if he needed her help. But Poseidon had asked him to include her and Triton never went against his father's orders. Yes, he had to admit that Persephone didn't have the same restrictions he did as a god, but Triton honestly didn't want to spent a moment longer in her company.

Switching between cursing the Fates and his father for his current position, Triton sighed and forced his face into emotionless mask as he spoke.

"My - Our father's" He quickly corrected himself, hating the bitter taste the word 'our' left on his tongue. "Trident was stollen. The trident is the source of most of his powers, so without it Poseidon doesn't have full control over his own domain."

Percy sighed, sitting back down on her chair, her face buried in her hands. She stayed still for a moment, composing herself. One peacefull day. Was it too much to ask? One day without having to worry about quests and monsters and gods.

If it was any other god she would have been reluctant to help (But would have eventually agreed because it was dangerous to refuse a god.) but this was her dad that needed her help. And despite the fact that she and Poseidon didn't exactly have typical close father/daughter relationship, she knew that deep down she loved her father.

Feeling uncharacteristically old at the sudden, the demigoddess sighed again and looked up towards Triton's eyes, which were so much like her own that it was a bit frightening. She had always had trouble with reading the god's emotions (especially when they tried to hide them as Triton was doing) but she was pretty sure that her half-brother was a bit worried.

"Do you now how it happened? Who took it?"

The god glanced at her silent mortal family, as if worried that he was sharing too much information with them and Percy gave him a small nod in assurance. They wouldn't tell anything, she knew. Her mother looked worried about her former lover and Paul, well, Paul wasn't very excited about it, but there was nothing he could do.

Triton obviously took her nod as enough reassurance and though he wasn't really trustful, he started explaining the situation. Apparently, while Poseidon had been out, dealing with one of the monsters that remained after Oceanus fleeing, he had dropped his trident to help one of the wounded merman. When he had looked back, his weapon of power was gone and neither he nor the others had sensed someone taking it.

"This is extremely worrisome." Triton concluded. "Poseidon's trident is one of the greatest weapons forged by the Cyclops. It has unbelievable power and if it falls in the wrong hands, well..." He didn't have to finish. Percy already knew how bad the situation was. She had retrieved Zeus' stolen master bolt a few years ago and knew exactly how powerful the weapons of the gods were. Especially those of the big three, Zeus, Poseidon and Hades.

"Do the other gods know?" The girl asked, though she felt she already knew the answer.

"No." Triton said sharply, his glare burning into her. "And they shouldn't. If Zeus and Hades find out that father is weaker, they wouldn't reconsider to overpower him."

Percy nodded distractedly, even though she didn't agree. The Olympians had always been paranoid, her father included, but she was pretty sure that Zeus wouldn't allow the balance of powers to be broken. Deep down (veeery deep down) Percy knew that they cared for each other. They were family after all. A messed up one, but family.

There was a short moment of silence, which was surprisingly broken by Sally.

"Do you know who did it?" She asked with a slightly trembling voice and all heads snapped towards her in surprise, before looking at Triton.

The sea god sighed, probably for the hundredth time since he had arrived, though this time it was in frustration.

"That's the problem." He said. "We can't know for sure. My father thinks it might be one of Oceanus' minions, though he is as confused as we are."

Percy nodded, seeing the logic. Last year, Oceanus had done all in his power to destroy Poseidon's palace in Atlantis, almost succeeding. He had fled after Kronos' defeat, but the girl doubted he had given up that easy, after being so close to the victory.

"What do you want me to do?" Percy asked, finally voicing the question that had been on her mind since the moment she had seen Triton's face at the door. She kind of feared the answer, not wanting to leave for another dangerous mission so soon.

"I want nothing from you," Triton grumbled, obviously displeased. "But my father asked to bring you with me on this search."

Percy's eyes widened. "With you? You will be going as well?"

The god raised an eyebrow. "What do you think girl?"

"But I thought the gods were forbidden from messing in mortal affairs?" She stuttered, blushing at her reaction as Triton rolled his eyes.

"This is not exactly mortal affair if you haven't noticed." He said as if it was obvious, crossing his arms in front of his chest. "So, will you do it?"

There was a tense moment of silence in which everyone's eyes were glued on Percy's face. The girl ran a hand through her hair, a nervous habit she had picked up a few years ago. She glanced at her mother, who didn't seem happy about it, but there was PRIMIRENIE in her face. The demigoddess forced herself to rethink the situation, though she already knew what her answer would be. Her father needed her now more than ever. And she wouldn't, couldn't, refuse his plead for help.

"I'll do it." She finally muttered, meeting Triton's eyes, surprised at the glint of approval there. He gave her a slight nod and stood to his feet.

"Good. First we must return to Atlantis and-"

"Wait!" Percy called out, now standing as well. "We are leaving now?"

Her half-brother gave her a look that made her feel extremely dumb at the moment.

"We don't have time to lose."

Percy hesitated, looking around the merrily decorated living room. "But it's Christmas." She murmured miserably.

Her mother hurried up to NAMESVAM SE. "Why don't you all stay for dinner and leave tomorrow morning?" She offered and Triton shot her a look of disbelief and annoyance. He opened his mouth to say something that probably would be insulting and Percy put a hand on his arm, surprising both of them. She shot him a warning glare, forcing her mouth in a fake smile.

"Triton, please, there is not much we could do tonight."

He looked conflicted, his jaw tensing as he gritted his teeth together, but eventually gave a curt nod. "You have tonight." He growled out. "I'll be back at dawn to pick you up. You better be ready."

He started shine with golden light and they all closed their eyes as he took his godly form and disappeared.

Once he was gone, Percy looked at her family with a frown.

"There goes my calm life." She muttered, picking up her still half-unwrapped present. Sally and Paul said nothing as they all resumed their holiday as if nothing had happened, but often shot Percy concerned glances. Finally she groaned, unable to stand their worried gazes and went to her room. She had to pack for a quest and with an ounce of sadness she realized that this was one of the things she was best at. During the last years she had gone on more life-threatening missions than any of the other demigods at camp and had gotten quite used to packing.

She stuffed some comfortable jeans and T-shirts in her backpack, a few squares ambrosia and a bottle of nectar, some money (both dollars and drachmas), her mobile (it was a present from Hermes so she could use it without worrying about attracting monsters) and some food. Percy wondered if she should take the keys of her car (birthday present from her parents) but quickly pushed the thought away. She was traveling with a god after all, transportation shouldn't be a problem. Plus, they were going under the sea.

Percy sighed and finally put her backpack away and changed into a large T-shirt she used for sleeping, setting her alarm for five a.m. (Triton had said they left at dawn and the gods had the habit of being in time) and tried to go to sleep. She turned and tossed for a while, her mind too busy to allow her rest, but finally her exhaustion took over.

She was walking, looking around herself. There were thousand mermen and other sea creatures around her, all kneeling in respect as she passed.

"Do you like it?" She heard a voice as behind her and turned to look at the man that had spoken. He was huge and scary, with hair that looked green under the dim light, that came from the surface and cruel blue eyes. In his hand he held a whip with three hissing sea snakes. It took Percy a moment to recognize him as she had never really seen him in person before.

"Oceanus." She growled and the titan laughed, though it wasn't a happy sound.

"You recognize me, I see." He said, fixing her with his gaze. "Do you like being powerful?" He asked again, gesturing around the kneeling crowd. "This could be true, you know? All you have to do is help me." His voice was silky and inviting and Percy found herself closing her eyes in pleasure, before she shook herself out of it.

"I'll never help you." She said angrily and Oceanus frowned deeply at her, his face shifting in a grimace of anger. The girl flinched, taking a step back in fear.

"You're father couldn't win this without his trident, you foolish demigod!" He snapped at her and the girl couldn't help but flinch as the water around her grew freezing cold. Usually the cold didn't bother her, being a daughter of the Sea god, but this time she felt it.

"Poseidon will fall as will the rest of the Olympians!" The girl gasped for breath as the water seemed to go thicker around her, the pressure growing more and more, preventing her from breathing. She was going to suffocate...

Percy's eyes opened suddenly and she took a deep breath, coughing. She was back in her room, lying on her bed, drenched in cold sweat. Her lungs burned as if she really had been just strangled and she groaned, taking large gulps of air. Her heart was beating quickly in her chest and it took her quite a while to calm down.

"Curse those demigod dreams!" She groaned, glancing over the clock on her nightstand. According to it, it was 3;07, which meant she had had only about four hours of sleep. With a growl, Percy ran a hand through her sweaty hair and stood up, knowing that no more sleep would come to her that night. She took a long shower to relax her tense muscles and by the time she made herself a coffee, it was already 4;30 and she could almost hear the coffee maker machine call her name. Half stumbling into the kitchen she made herself a coffee and sat down. This would be a long, long wait.
