Prologue

Brooke and Halcyon stood across the street. They seemed to be looking out for something. They knew that something bad was going to happen.

And just like that, it happened.

Flames erupted over the tall buildings of Manhattan, lightly charring the well-worked concrete.

People ran, screamed and panicked.

The twins stood back-to-back.

Then, Brooke brushed her blonde hair off her face and clenched her fists.

All of a sudden, her eyes began to glow minty blue. A gushing jet of water extravasated from the base of her feet. She pointed her index towards a large pyre in front of her. The water obeyed, and impressed itself over the wisps of fire. The fire reduced, but continued to advance.

Halcyon shot up into the air, whirled around, and like Brooke's, his eyes too, glowed blue. Then, wisps of water encircled around him, gradually growing into thicker wisps. Finally, Halcyon darted backwards, and the wisps transformed into a gyrating maelstrom, which vertically advanced the bigger flames and erupted.

The flames at once vanished, but someone kept raising the power of the flames, resulting in increase in the fire.

The twins realized that their power wasn't strong enough to extinguish the fires erupting.

Then, all of a sudden, a bluish light descended between the two. The fire seemed to deflect now, but continued to increase after the light faded, revealing a woman.

She was 6 feet tall, with flowing golden hair. Her skin was flawless, and she wore a robe, emblazoning with ultramarine blue. She wore a tiara on her head, with a beautiful deep-sapphire embedded in it.

She clenched her fists, closed her eyes and gravity was defied for a few seconds. A strong power was pulsating within her. The woman opened her eyes. Halcyon and Brooke grabbed the woman's waist out of oblivion, and thick crescents of water ripped around the woman's aura.

The next moment, the fire was gone. Completely.

Smoke rose in the aftermath.

Halcyon and Brooke opened their eyes. They weren't surprised at the fire vanishing and let go of the woman.

"Thank god you were here on time" Brooke thanked the woman.

"My power is weak, children. You'll have to survive on your own" the kind woman said.

"What? We're barely fourteen! Our powers haven't even reached their peaks yet!" Halcyon pointed.

"I am aware of that, Halcyon. But my powers have failed to cooperate with my will. And besides, you haven't used your existing potentials yet. And you will need to, to bring down the fire-causing being" explained the woman.

"We aren't gonna let you down, Thetis. Hal's just tired" Brooke elaborated.

"Fine then. I hope you return victorious" Thetis announced, giving them elixirs.

"This ambrosia increases the health of you demigods"

Halcyon and Brooke drank from the vials, and instantly felt full of power.

"Wow, I'm glad this works. Unlike that hair softening thing I bought" Halcyon stated.

"No time for jokes. New York depends on you two. And the world probably depends on you demigods" Thetis concluded, fading into thin air.

"Yes, leave us in the middle of New York, searching for a fire creating monster" Halcyon complained.

"Halcyon! Respect!" Brooke advised.

"Yes, moral police"

The twin duo ran towards the tall building with the beacon on top. The beacon glowed a crimson red.

"This is it. The fire's coming from here" Brooke concluded.

"Really? I would've never guessed" Halcyon counterbalanced.

They walked into the doors, which were definitely rosewood, decorated with gold embellishments. The foyer was long, incredibly solitary and was oddly lit by girasol-colored lamps. The foyer led to an elevator, which seemed like pure gold.

"This place gives me the creeps" Brooke admitted.

"Really?" Halcyon sarcastically replied.

"Gosh, you and your sarcasm"

"Sarcasm and Cynicism are the only two languages I speak, hon"

Brooke pressed the button which was engraved into the gold. The elevator immediately opened.

"Don't you think this is...a little too easy?" Halcyon pointed.

"Um, why?"

"Because we're in enemy headquarters, and we're taking an elevator to our mystery nemesis"

"I suppose you're right. But we don't have a choice"

Halcyon and Brooke remorsefully entered the gorgeous elevator.

It had a thick red carpet on the floor, which made you wanna sleep on it. There were mirrors, which were royally decorated with velvet curtains around the corners. It was a beautiful elevator.

"Wow, cozy"

"Yes" Brooke replied.

There was only one button inside the elevator. It read '∞'

"Infinity? What's that supposed to mean?"

"I have no idea. But it's not like we have a choice" Brooke reminded Halcyon.

"Of course we do! Let's get out of here!"

The elevator doors shut quickly.

"Well. I guess you were right" Halcyon ruefully admitted, with absolutely no tone of sarcasm.

But he quickly shot back to his usual tone: "Not a good idea, I think"

The lights in the elevator dimmed to a spotlight, red in color. Hal and Brooke came closer to each other. Then, the elevator started to ascend rapidly.

"WE DIDN'T EVEN PRESS THE BUTTON!" Halcyon screamed.

" We're the children of Poseidon for god's sake! The god of seas! Be calm!" Brooke managed.

"Brooke? He's also the god of earthquakes. And the seas are rather stormy this time of year. Counterproductive much?" Halcyon reminded.

The elevator swiftly shot up with even faster speed and came to a sudden halt.

"I'd puke, only this elevator's too gorgeous" Halcyon admitted.

The doors opened.

The beacon was here, and this was the terrace patio.

Standing outside was someone they'd never expect to find: Eric.

Halcyon's face was dripping with sweat, and he quickly brushed his messy, deep-golden hair of his face.

"What're you doing here?" Halcyon demanded.

"What do you MEAN? You're telling me you didn't know it was me all along? Bah! Were you abacinated or something?" Eric questioned, amused.

"I knew it was you, you traitor!" Brooke furiously uttered.

"Ah, so my attractiveness affected you, Brooke? I'm impressed. By me, of course" Eric put forth.

"You're filthy! I'm sure Hephaestus rues having claimed you!" Halcyon rebutted.

"Humph. Who're you to speak, son of stable-boy?" Eric spat.

"Stable-Boy? Seriously? That's the best you could come up with? Gosh, you had me fooled that you were worth a good nemesis" Hal summoned.

"Aargh! I've had enough of you twins! Charon shall carry your filthy souls across River Acheron!" Eric erupted.

"You have no idea what you just said. You're gonna pay" Halcyon challenged.

"Then show me what you've got, kelp-head" Eric fired back.
