Set sometime around MoA. When they first boarded Argo II.
It was pitch black. No matter what direction he looked at (he wasn't even really sure what direction he was looking at) there was an endless stretch of darkness. Cold wind swept past him, making Percy shiver. There was something unusual about this place. Something familiar. The cold breeze passed him again, as if urging him to step forward. Percy's teeth chattered from the cold and he wrapped his arms around himself in an attempt to stay warm. The son of Poseidon walked forward, allowing the ever icy wind to guide him in the darkness. He had walked for what seemed like forever when he suddenly crashed against a cold, hard surface and fell hard. Percy blinked in confusion, staring at the object that stood in his path.
...son of the Sea God...
...trapped..
Voices murmured, as if awakened by the appearance of the Earth-Shaker's son. Percy turned, his hand immediately diving into his pocket for Riptide. He pulled out the pen and uncapped, Riptide's true form emerging.
...Lost son..
...Poseidon...
...change his fate...
...one will falter..
Percy's eyes darted around, trying to locate the source of the voices. But it seemed as if it was everywhere, all around him.
...Perseus.
The boy jolted at the sound of his name. He turned, Riptide in hand.
Perseus.
The voice sounded gentle and filled with so much familiarity that it made Percy rack his brain for someone he knew. Yet, he could not match the voice to anyone.
The hero's eyes widened in surprise as the object before him started to glow dimly. Riptide was slowly lowered and Percy stepped forward, his free hand coming in contact with the hard, see-through, icy surface. He vaguely became aware of the voices slowly fading.
Before him stood a sphere made of ice. But it wasn't because of that that Percy was immobile. It was what was inside that made him freeze. Suspended at the center of the sphere was the form of a person who was curled up. Arms had drawn legs to its chest and the person's head rested on the figure's knees, hiding the face from view. Long brown locks attached to her (or him, Percy had no idea) head floated around her (he still can't decide if the person was a guy or a girl) like a halo. A black coat flowed around the figure, showing off what skinny body the person had.
"Hey!"
Percy yelled, trying to get the attention of the person inside. He tapped on the icy prison, trying to get the figure's attention. But then he stopped, eyes widening (almost comically) again. The fact that the person did not seem frozen inside the sphere finally registered into his mind. The hair, the coat—it was flowing. The hero stepped back, eyes trailing over to the symbol that glowed dimly behind the sphere.
A trident.
Poseidon's symbol.
Poseidon.
The realization finally hit him and Percy staggered back, crashing into the floor.
In the Tomb of Eternal Ice,
Deep in the Cave of Deathly Sighs,
Lies a Hero in wait
for the Son of Poseidon to change his fate.
The quieted voices once again spoke.
But beware, Son of the God of the Sea,
Everything is not as you see.
The Lost Son of Poseidon, you must find
For your fates are intertwined.
Percy was beyond confused, but nonetheless, he listened.
Victory will be yours against the Trial of Fire and Water,
Yet in face of the Masked Enemy, one will falter.
One of two shall remain firm and from the ashes he shall rise,
But the other one must succumb to his fated demise.
He looked up and swallowed the lump in his throat as the figure slowly raised its head. Eyes fluttered open and Percy found himself staring into deep sea-green eyes.
Percy jolted awake, beads of sweat running down his face. Demigod dreams always sucked. And for Perseus Jackson, it was always more of a nightmare than a dream— more real than imaginary. It seemed as if these dreams were more extreme in his case. And Percy hated them. The son of Poseidon sat. He gathered his legs to his chest, pressing his forehead against his knees.
The Lost Son of Poseidon, you must find.
The line echoed over and over in his head.
For your fates are intertwined.
He sighed, pulling at his hair in frustration. Already, he could feel an oncoming headache.
Another prophecy? He mused, I've already got enough on my plate as it is. And now.. this?
Percy had no idea what to think anymore. With the threat of Gaia's rising, the rift between the Roman and Greek Demigods and everything in between, he was starting to fall behind.
For the love of Aphrodite, Percy thought mournfully, Someone has it in for me up there. I bet it's Ares.
He shook his head, ridding away such thoughts. Now, he had something new to worry about.
Poseidon's lost son.
His half-brother.
Who's missing.
A half-brother.
Who isn't Tyson.
Great.
But if Poseidon had another demigod child, could it be that he had broken the oath they had taken?
What in Zeus' name is this? Percy sighed, yet again, and massaged his temples. I need a break.
