Fourth Chapter. I'm not sure how long this is actually going to end up being, but definitely at least five more chapters. Keep up the reviews and I'll keep up the updates. I think this is how I'm going to operate for all my crossovers, not my regular fics but I have a tendency to lose interest in crossovers. That being said, I don't own PJO or Halo. Enjoy.
The craft shook as it shot out of the forerunner planet's gravity well. Alarms flashed as the sensors detected a slipspace rupture ahead of them, only a few hundred kilometers. Then, in a flash of purplish light a covenant cruiser appeared. Percy grinned beneath his helmet, now changed and glowing with sea green accents. The forerunner ship he had been given was slightly larger than a pelican, and fitted with enough weapons to scrap the massive cruiser in front of him, but he didn't need to attack. The two ships stared each other down for a minute before the cruiser's fighter bays opened and banshees poured out by the thousands. As they prepared to fire at him the smaller ships detonated in soundless blasts of purple energy. Percy's ship blasted forward and spun around a field of debris before stopping suddenly only a kilometer off their bow.
"Hail them." Percy told Beth, she complied and a few seconds later a gruff voice came over the speakers.
"Identify yourself." It ordered.
"You dare order me Sangheili swine? I am Forerunner, you are an ant beneath my boot." Percy responded in a strange language. There was a pause,
"I apologize. I beg your forgiveness for firing upon you, we simply thought you were one of the heretics." The elite begged.
"Return to your home world and spread the word. The Forerunners are offended by your worship of us. The Great Journey is not what you believe it to be, do not allow this false worship to continue." Percy ordered. The Elite didn't argue, but the ship jumped back to slipspace.
"That went… Well?" Beth asked.
"That's a single ship that believes their campaign is wrong now. That's enough for the seed of doubt to be planted. The war is as good as lost for the covenant now." Percy grinned beneath his helmet and took a deep breath.
"Take us to Earth Beth. The librarian didn't fill you in on my past, but I'm about to." Percy commanded. The small ship jumped to slipspace a moment later.
Earth had very good defenses. As he dropped out of slipspace at least three orbital MAC gun emplacements were locked onto him.
"Clearance Alpha Bravo Zulu Zulu Foxtrot." Percy spoke into the radio. The MAC guns moved back to their original positions and Percy headed for the planet's surface, New York to be precise. Olympus hadn't moved, neither had Camp Half-Blood. The Forerunner ship, glowing blue, touched down firmly just outside the borders, Beth remained silent as he jogged easily up the hill and stepped across the border. Immediately the familiar layout of Camp Half-Blood appeared below him. All at once a phalanx gathered and headed toward him. Percy sprinted down the hill, only a blur to the campers, and jumped over them. He landed beside the campfire, which was only a few embers at this point. Percy straightened and approached his old sword sadly. With a sharp breath he dispersed his armor, it dissolved into light and Beth appeared in physical form beside him. Percy reached out and gripped Riptide firmly, it hummed to life and glowed blue. Then he tugged. The blade slid out of the ground easily and Percy hefted it slowly. There was a godly flash, multiplied by ten, in front of him as most of the Olympian council appeared. They gaped at him and he scoffed.
"What is this?" Athena, the supposed smart one, asked.
"I came back for my sword." Percy answered. Artemis glared at him and drew her bow, an arrow knocked.
"Percy…" Beth warned. But as she finished his armor was already appearing on his body once again, the sword nowhere to be found. The arrow bounced off his visor weakly and Percy shook his helmeted head.
"You haven't righted the wrongs yet. I can't help you when the covenant reaches Earth." He warned. The gods glared at him.
"They will never find Earth! The Cole Protocol will prevent them from ever discovering our largest colonies." Zeus argued.
"Silence Zeus. You are lucky I don't wake the guardian and destroy your world myself. I'm not your pawn anymore, I'm a Forerunner now. Either you can grow up and fix what you broke or you'll all die." Percy warned. He held out his hand and Beth took it, once more disappearing into his armor. Percy turned and headed for his ship, but found himself surrounded by the gods and their children. With a silent command his ship powered up and lifted off, hovering over the borders until it was right above him. Then his body vanished with a dim light and the ship rocketed away.
Reach would fall soon. Percy knew exactly when the Covenant would find it, using a simple seeker crystal they would track an UNSC ship through slipspace and destroy Earth's military strong point, then attack Earth itself. He piloted the craft down through the atmosphere and landed in a secluded piece of forest. He walked down out of the craft's aft ramp and sat on a rock. There was a rustle in the leaves and the girl he had blasted out an airlock stepped out of the trees, enraged. Percy stood as she rushed him.
"Aren't you going to protect yourself?" Beth asked as the lightning bug drew closer.
"Nah, I don't want to hurt her." He replied. Thalia punched and kicked at his armor with no effect, even blasting his form with lightning bolts. But he didn't move at all.
"What's with this?" she complained.
"Are you done?" Percy asked. She nodded in defeat and sat down. Percy sat down near her and took a deep breath. "I remember now Thalia. I'm sorry for blasting you out an airlock." Percy said.
"It's fine, at least you made sure my helmet was on." She shrugged.
"Anyway, the Olympians are going to lose this war if they don't make things right with me. I can't fight if they don't. And I may no longer be a demigod, but I am a Spartan, and with Forerunner upgrades. The Covenant is going to be on the backfoot soon, but they'll manage to destroy Reach and find Earth before then. They could save thousands of lives by making right what was wronged." Percy started.
"They've been pissing me off lately. Poseidon denies that he ever had plans to overthrow Olympus of course, but he made Annabeth his wife and made her immortal." Thalia informed him.
"Wait, Annabeth?" Beth asked. Percy's armor dispensed and Beth's physical form appeared on the ground beside the pair. She was looking at him expectantly.
"Thalia, Beth. Beth, Thalia." Percy introduced them.
"Who is this Annabeth?" Beth asked Thalia.
"Daughter of Athena, her and Percy used to date but he found out she was pregnant with his half-brother and blah blah blah. Then Percy swore never to help Olympus until they had righted the wrongs against him and he stabbed himself with his sword, sealing the oath." Thalia summarized.
"Oh." Beth mouthed. She watched Percy with concern evident in her strangely human eyes. Her intelligent eyes. Then Percy realized, Beth wasn't a normal AI.
"How were you created Beth?" Percy asked suddenly.
"A piece of Dr. Wise's brain was used to write my basic form. Why?" she answered.
Ooooh cliffhanger. What's up with Beth? How will the Olympians save their skin and right the wrongs against Percy before the Covenant find Earth? Review to find out!
