2: The Place That Should Not Exist

By the time we made it back to Camp Half-Blood, the sky still wasn’t right.

You’d think crossing the magical border would fix everything—reset the weirdness, make the world feel normal again. That’s usually how it works. Monsters outside, safety inside, magical barrier doing its thing like an invisible force field powered by ancient Greek anxiety. But this time, as we crossed the hill, I felt it immediately: whatever we had seen in the city hadn’t stayed behind. It had followed us—or at least, its presence had.

The camp looked the same at first glance. The cabins, the strawberry fields, the Big House sitting peacefully like nothing was wrong. But then you noticed the details. Campers had gathered in small groups, whispering. No one was training. No laughter, no sword fights, no Athena kids arguing about architecture. Even the pegasi were restless, stomping around like they could sense something in the air. And overhead, the sky… it wasn’t entirely dark anymore, but faint streaks of shadow still lingered, like someone had tried to erase them and failed.

“Okay,” I said under my breath as we walked down the hill, “that’s not normal.”

“Nothing about this is normal,” Annabeth replied. She looked exhausted, but in the Annabeth way—like her brain was working faster, harder, trying to solve a problem that didn’t have enough pieces yet.

Grover was clutching his reed pipes like they were a lifeline. “I really, really don’t like this. The nature spirits won’t even talk to me. They’re hiding.”

“That bad?” I asked.

He nodded. “When dryads start ghosting you, Percy, it means something ancient has woken up. Something older than them.”

Before I could respond, a voice cut across the camp. “Percy!”

I turned just in time to see Chiron trotting toward us, his horse half kicking up dust. His expression was serious—more serious than usual, and that said a lot. Right behind him, Mr. D leaned against the porch of the Big House, looking unusually… attentive. That alone made my stomach drop.

“Ah,” Mr. D said lazily, though there was a sharp edge to his voice. “The problem child returns. And, judging by the look on your face, you’ve managed to make things worse again. Impressive, even for you.”

“I didn’t start this!” I protested.

“You never do,” he said. “And yet, here we are.”

Chiron raised a hand. “Enough, Dionysus. Percy, Annabeth, Grover—you encountered it, didn’t you?”

Annabeth nodded. “In Manhattan. It broke through the sky. Not like a monster—like something forcing its way into reality. Grover said it felt older than Olympus.”

Chiron’s face tightened. “Yes… that confirms it.”

“Confirms what?” I asked. “Because so far, I’ve just got ‘mysterious shadow thing that says creepy stuff and knows my name.’”

Mr. D let out a dry laugh. “Oh, you poor, clueless demigod. You always think the worst thing out there is something you’ve heard of.”

Annabeth crossed her arms. “Then tell us. What is it?”

There was a pause. Even the wind seemed to hold its breath again.

Chiron spoke quietly. “It is something that should not exist anymore.”

“Okay,” I said. “That’s officially worse.”

Chiron gestured for us to follow him inside the Big House. We moved quickly, the tension in the air thick enough to choke on. Once inside, he shut the door and lowered his voice. “Long before the Olympian gods established their rule, before Zeus, Poseidon, and Hades divided the world… there were others.”

Annabeth’s eyes widened slightly. “Primordial beings?”

“Older,” Mr. D muttered. “And far more inconvenient.”

“They were not worshipped in the same way as the Olympians,” Chiron continued. “They represented things… concepts that were unstable, dangerous. Reality itself was not as… fixed as it is now. These beings were part of that chaos.”

I frowned. “So what happened to them?”

Chiron hesitated. “They were erased.”

The word hit harder than I expected.

“Erased?” Grover repeated. “You mean, like… destroyed?”

“No,” Annabeth said slowly, her voice barely above a whisper. “Not destroyed. Forgotten.”

Chiron nodded. “Exactly. The Olympians, along with forces even they could not fully control, removed these entities from history. Their names, their symbols, their stories—wiped clean. As if they had never existed at all.”

“Then how is one of them back?” I asked.

Mr. D picked up a Diet Coke and popped it open. “Ah. Now that is the interesting question.”

Annabeth started pacing. “Something must have triggered it. You can’t just… come back from being erased. That would require—” she stopped abruptly.

“Reality instability,” she whispered. “Something’s breaking.”

“Very good,” Mr. D said, giving her a slow clap that somehow felt insulting. “Finally, someone using their brain.”

I ran a hand through my hair. “Okay, so we’ve got a forgotten god-thing breaking back into existence, messing up the sky, and apparently it knows me personally. Great. Love that.”

Chiron looked at me carefully. “Yes… that is the part that concerns me most.”

“Why me?” I asked. “I’ve never heard of this thing before.”

“That may be precisely the problem,” he said.

Before I could ask what that meant, the ground shook again—stronger this time. A distant crash echoed from somewhere deeper in camp, followed by shouting.

We all froze.

“That came from the woods,” Grover said, his voice trembling.

Another rumble. Louder. Closer.

Mr. D sighed. “Honestly. Can we not have one conversation without something exploding?”

Chiron was already moving. “Come. Whatever it is, we must act quickly.”

We rushed outside. Campers were running toward the forest’s edge, weapons drawn. The ground near the tree line was cracked, blackened, like something had clawed its way up from below.

And then I saw it.

Another creature—but smaller than the one in the city. This one was… incomplete. Its form flickered, like a glitch in a video game. Parts of it would appear, disappear, then reappear in the wrong place. Its limbs stretched too long, then snapped back into something almost normal, except not quite.

“What is that?” a camper shouted.

“No idea!” someone else yelled.

The creature let out a distorted, scraping cry and lunged forward. One of the campers swung a sword, connecting—but instead of cutting, the blade seemed to… pass through it halfway, like it couldn’t decide if the creature was solid or not.

“Don’t let it reach the cabins!” Annabeth shouted.

I didn’t wait. Riptide was already in my hand as I charged forward.

The creature turned toward me immediately.

Great. Again with that.

“Child of the sea…” it whispered, the same voice as before, echoing from nowhere and everywhere.

“Yeah, yeah, I heard you the first time,” I muttered, tightening my grip on my sword. “Mind explaining what your deal is?”

It tilted its head—unnaturally, like the angle didn’t make sense.

“You remember… fragments,” it said. “Enough to matter.”

“I don’t remember anything!” I shot back.

That’s when it smiled.

Or at least, I think it was supposed to be a smile.

“You will.”

Then it attacked.

I barely blocked in time, the impact sending a shock up my arms. The blade connected this time—but the creature flickered again, and suddenly my sword hit nothing but air.

“Percy!” Annabeth yelled. “It’s unstable! You have to time it—wait for it to solidify!”

“Great tip!” I said as I dodged another swipe. “Little late!”

Grover raised his pipes and began to play—a shaky tune at first, but it grew stronger, steadier. The ground responded, roots breaking through the soil, wrapping around the creature’s legs—if you could call them that.

For a moment, it held.

Then the creature screamed.

The sound was wrong. Too deep, too layered.

The roots shattered.

The creature surged forward—

And I felt something shift.

The air changed. The world tilted.

For a split second, everything around me looked… different. Older. Warped.

And I saw it.

Not the creature.

Something behind it.

A symbol.

The same one from before.

Burned into the fabric of reality itself.

Then it was gone.

The creature froze.

Just long enough.

I didn’t hesitate.

I stepped forward and drove Riptide straight through its core.

This time, it worked.

The creature let out a final, broken sound before collapsing in on itself, fading into nothing like it had never been there at all.

Silence fell over the camp.

No cheers.

No relief.

Just fear.

I stood there, breathing hard, my heart racing.

Annabeth came up beside me. “Percy… what did you see?”

I swallowed.

“I don’t know,” I admitted. “But whatever this is…”

I looked up at the sky, where the shadows still lingered.

“…it’s not just coming back.”

I tightened my grip on Riptide.

“It’s rewriting everything.”
