Reincarnation in the PJO verse: Volume 1

『Diedre meets some old friends』

The entire city was a war zone. Diedre's eyes popped out, trying to keep up with the constant clangs and jabs from everyone. His eyes wandered to try and find his cabin mates in the midst. 

He sighed in relief when he couldn't find the little ones. 

Was it bad of him to do so? Probably. But he was doing it, so no looking back. He spotted Vilian being backed into a corner and found a place to help.

He moved to whisper into Percy's ears, "Percy, don't be so trusting of those who try to help you with absurd demands."

Percy moved towards him, his shock emitting from him as he tried to say something, but before he could, Diedre moved to say to Blackjack, "Drop me right there, buddy."

Diedre jumped right next to Vilian, who was pulling out a sword fight with a gun.

He was so very proud of her.

"Hey Vil, updates," he said, nocking an arrow on the bow to aim into one of the tiny imbeciles that had come into their circle of defence. 

"The monsters don't seem to stop," Vilian said, still knocking an arrow, but now he could see the visible look of strain on her face.

Diedre could only helplessly look as she continued, "We lost so many Xythos, Michael and now the young ones have to go through this. I hate it."

Of course, Diedre hated it too. Never knowing when the next blow would come, or will the next blow would bring him to his second death. 

"We just need to hold them off a bit more," he said, throwing his sword forward to impale the group and then he heard it.

A chorus of horns answered from all around them, echoing off the buildings of Manhattan.

The horns got louder. 

Thank god, Chiron had rallied the centaurs.

Then, to their left, a hundred monsters cried out at once. Kronos's entire northern flank surged forward. A new blast of horns shattered the night. The air shimmered. In a blur of movement, an entire cavalry appeared as if dropping out of light speed.

"Yeah, baby!" a voice wailed. "PARTY!"

A shower of arrows arced over their heads and slammed into the enemy, vaporising hundreds of demons. But these weren't regular arrows. They made whizzy sounds as they flew, like WHEEEEEE! Some had pinwheels attached to them. Others had boxing gloves rather than points.

"Centaurs!" Annabeth yelled.

The Party Pony army exploded into our midst in a riot of colours: tie-dyed shirts, rainbow Afro wigs, oversized sunglasses, and war-painted faces. Some had slogans scrawled across their flanks like HORSEZ PWN or KRONOS SUX.

Hundreds of them filled the entire block. 

"Percy!" Chiron shouted across the sea of wild centaurs. He was dressed in armour from the waist up, his bow in his hand, and he was grinning in satisfaction. "Sorry, we're late!"

"DUDE!" Another centaur yelled. "Talk later. WASTE MONSTERS NOW!"

He locked and loaded a double-barrel paint gun and blasted an enemy hellhound bright pink. The paint must've been mixed with Celestial bronze dust or something, because as soon as it splattered the hellhound, the monster yelped and dissolved into a pink-and-black puddle.

"PARTY PONIES," a centaur yelled. "SOUTH FLORIDA!"
Somewhere across the battlefield, a twangy voice yelled back, "HEART OF TEXAS CHAPTER!" "HAWAII OWNS YOUR FACES!" a third one shouted.

"Stop running, you fools!" Kronos yelled. "Stand and ACKK!"

That last part was because a panicked Hyperborean giant stumbled backwards and sat on top of him. The lord of time disappeared under a giant blue butt.
