The New World

Chapter 4

Annabeth bolted straight up as she heard a horn blowing in the distance. She and the rest of her cabin rushed out in various states of undress, and armor.

They ran to Half-Blood Hill where the Hunters of Artemis were slowly being overwhelmed by a horde of Trikru warriors (A/N- About 100).

With a yell Thalia let loose a wave of lightning emanting from her in a wave and Trikru warriors fell like stones and the rest retreated while campers chased them away from the border.

While they did have a magical barrier it didn't stop some warriors from coming through. Apparently they were probably far off legacies, but they were in no way allies, because three of them had made it through one night and assassinated ten campers from various cabins before they were caught.

But the upside to this, is that Trikru would eventually run out of legacies and then Camp would be safe.

"Annabeth," Thalia, now lieutenant of the Hunt since Zoe died in the Titan war and one of the Seven.

Annabeth sighed as she thought about the differences between this life and her last one.

Luke had never gone over to Kronos. Kronos's host was Ethan Nakamura. Luke had also been one of the Seven.

They had succeeded in bringing the Roman and Greek demigods together and Reyna had brought back the Athena Parthenos to the Greeks with Coach Hedge and Bianca.

Bianca never died... But Percy wasn't in this world...

And then the world was wiped out by nukes...

That was seventy five years ago...

Seventy five years since their families had died...

Ninety three years since she had been reborn...

Ninety three years without Percy...

Of course she had moved on and was with Luke now, but a part of her felt guilty about it and-

"Annabeth," Thalia repeated a little more loudly.

"Hm?" she said as Thalia shook her shoulders, jolting her out of her thoughts.

"I said there's no wounded, but they had set fire to the strawberry fields. The nymphs put it out, but we need to make a retalitory attack."

"Yeah, have the Apollo cabin take the flying chariot and rain hell on the nearest Trikru village. Let's teach them to never mess with us again," Annabeth replied darkly.

The campers had woken up two weeks ago realizing that seventy five years had passed and that the Earth had healed outside their borders, but there were weird twists.

For example, the forests around Camp Half Blood glowed in the dark after a rain storm, or the fact that there was a whole clan of warriors right outside their borders, or the fact that civilization as they knew it was gone.

Annabeth sighed looking off into the distance longingly. Where are you when I need you Percy?

A lonely little line break\

Abby swallowed as Percy and his friends had told their story for the fourth time that day. They had come from a parallel universe that had heard of a threat in this world that could very well spread across the multiverse. They had been sent by their superiors to neutralize that threat and to bring peace to the Alieverse as they had called it. For what reason? She didn't know.

What proof did they give that they were from a different universe?

Their blood...

Each of the four were missing half of the helix in their DNA strands.

No one Abby had ever encountered had that... Not one on the Ark or any grounders she'd come into contact with...

And not to mention that their blood had strange golden flakes in it...

And the faxt that being from a different universe gave them powers in the "Alieverse."

Percy with his powers over the sea, Jason over the sky, Nico with death, and Will? She had no idea what to make of the boy. He was very skilled at music, archery, and was even a skilled medic, along with many other things.

Now the boys themselves were very similar to the Grounders as they were very well-trained in combat and were always very alert with their surroundings.

They certainly had the weapons to blend in with the grounders, with swords and spears and whatnot, but they were strange. They had jeans and the material wasn't synthetic at all... It was like they had came straight from the past, but they told her that where they had come from there was never any threat of a nuclear apocalypse and that their Earth was still very intact and was progressing with technology at a decent rate.

Abby still had trouble wrapping her head around it, but when the Percy look-alike had pulled out a phone, not unlike the newly renamed Arkadia's tablets, it confirmed it. In fact it was small, very mobile and it was chock full of pictures of the four guys' universe. They had music on it, games, and a hell of a lot more stuff that she had no idea did. Their world apparently was very laid-back since they had the time and comfort to entertain themselves.

She turned the phone over and rubbed at the silver symbol of an apple.

Strange, she thought.

"Abby?" Kane asked as he tapped her shaking her from her thought process.

"Yeah sorry, I'm still having trouble wrapping my head around this," Abby shook her head.

"Well you guys are free to make yourselves at home I guess," Kane said as he and Chancellor Abby exited the Chancellor's office.

"Well, where should we set up our tent?" Will asked the other three.

6 Months Later...

"There's still no sign of Clarke," Bellamy said as he pointed at the map.

"We've gone as close to the border of Sector Eight as we could, but no sign of her Sir," Bellamy stated as he faced Kane.

"Alright well she could very well be in Azgeda territory or she could even be somewhere totally different," Kane rubbed his chin thoughtfully.

"We'll deal with this later to let the Chancellor rest. She hasn't been getting much sleep since Clarke left," Kane sighed.

"All right," Bellamy said quietly as he silently left the room.

Marcus stared at the board wondering if Clarke was in Azgeda territory when Abby cleared her throat.

"Don't worry we'll find her sooner or later," Kane told Abby as she got up from the couch.

"I know we will," she replied worriedly. "I'm just praying that it won't be her dead body that we find."

*Flashback to about 2015* (The timeline is a little different from the canonical timelines of the 100 and PJO meaning the Ark comes down in 2100, while Percy and the others are from about 2017)

Annabeth slowly sat up as her senses were bombarded with different sensations.

Pain... Ringing in her ears... Her head throbbing...

There had been a giant flash of light and a resounding boom and then darkness.

She stood up dusting herself off. There were various campers around her on the ground picking themselves up off of it.

A crescendo of voices were worriedly asking her what that was, why the sky lit up, what that sound was, since they looked at her and Luke as the leaders of camp.

"Alright everyone, calm down," she yelled as she regained back control of the crowd.

"First things first. Is anyone hurt?" After a chorus of no's she nodded. "Ok, everyone below 10 into the Big House with Piper."

Annabeth waited as Piper herded the younger demigods into the Big House subtly charmspeaking them, muttering that everything would be fine and that Annabeth would take care of it.

"Ok, first off let's fan out in teams of six based on your battle buddies and team leaders," she commanded.

"Fan out and check the border to see if any monsters made it past. Remember the mission is recon and report back to me in ten minutes at Thalia's tree. Luke, Piper, and Jason with me to Half-Blood Hill."

The demigods went about and did their assigned tasks, but many stopped as they saw the edges of camp.

Annabeth let out a gasp as she stared down Half-Blood Hill at all the destruction beyond the camp's borders.

"Annabeth what happened?" several demigods were asking as they rushed to her.

"The mortal world is gone... The idiots went and destroyed the world with nukes," she said shakily.

Several demigods let out a sob as they realized that their families were dead. Annabeth steeled her face and pushed aside her emotions as she realized that the Greeks and Romans were the only ones left in the world.

Camp Half-Blood would need strong leadership in the coming times following this Apocalypse.

A/N- Hey all! No, I'm not dead and yes I'm sorry for not updating for three months, but I've been pretty busy... Anyway, these past couple of months have allowed "plot bunnies" (for lack of a better word) to sift around in my brain. For once I have an idea of where I want this story to go. So hopefully, I'll be able to turn out chapters at a faster rate, but I have no idea... Thanks for reading this far and don't get stolen...

Kattrina123- Thanks for reviewing!!! I'll try to update more, but no promises. *sigh* School is a hell upon itself. Well anyway thanks for the support!!!
