Chapter 9: Alastor the Sword of Thunder

You guys want to hear another one of my stupid betrayal story ideas? A cross over with CF Vanguard where three of them (Percy, Jason, and Piper) are actually hosts to the spirits of units.

'I understand, Sparda but please respect my love life.' Nero thought back, still making out with the daughter of Venus.

"Okay, okay but you have to leave sometime during today." the demon's voice replied back. Suddenly, the two lovebirds pulled away.

"Per...I mean...Nero, what's wrong?" Piper asked the son of Vesta, who was deep in thought.

"I'll be fine, Beauty Queen." he replied back. She smirked a little before getting off the bed.

"Get your rest, Hotshot." Piper said as she left him alone in the infirmary. When he was all alone, Nero quietly stood up and wrote a note that said:

Beauty Queen,

I know how to end this 'Savior' issue once and for all. But this is something I have to do alone. I'm sorry, but I don't want to endanger your life anymore. Stay here at New Rome, where you're safe.

XOXO (if you're reading this, Piper),

Perseus Jackson/Nero Redgrave

P.S. Take care of my sword and guns for me.

When he was finished, he placed it on his bed, grabbed Yamato ONLY, and silently escaped the infirmary.

"Thalia's alive...Thalia's alive..." Jason constantly muttered to himself, pacing around the Principia as he did so.

"Jason, this is a little too unhealthy for you." Reyna reminded him as she watched her fellow praetor walk around like a malfunctioning robo-dog.

"I know but, Reyna, my sister's alive and I haven't seen her in a long ass time!"

"We have a 'graecus on a colossus' problem to deal with, Golden Boy!"

"Okay, okay! What do we do?" the son of Jupiter asked.

"What if we mix up Greece and Rome?" she suggested, only for Jason's jaw to drop onto the ground.

"That's...That's insane, Reyna! Octavian will get pissed off and attack them!" he yelled back.

"If Per...Nero, trusts them, I will too."

"How do we know they're not with that Minerva spawn?"

"If they were with her, then we would have known by now."

Concerned, Jason stepped out of the Principia and all the way to the border between the city and the Field of Mars, where the Savior remained stationary on the plains. Gods, lares and demigods alike, all armed, stood at the ready should it attack. Some of the other Olympians, however, remained on Olympus in case something else happens. The only gods in Camp Jupiter are Minerva, Mars, Apollo, and Diana.

"Any signs of new activity, Lady Minerva?" the son of Jupiter asked.

"It still hasn't moved yet but it's giving off a strange aura similar to Percy's katana." the wisdom goddess replied.

"Say what?" Jason questioned.

Minerva cursed her big mouth under her breath.

"It's as if the katana, Yamato, and whatever's charging that colossus are connected." she said.

The conversation could no longer be continued when what looked like animated suits of Greek battle armor charged emerged from a flap in the chest of the Savior. They were armed with the generic sword and shield set, and were massive in numbers.

"That...is...a...lot." Apollo muttered.

"Romans! Shield Wall!" Reyna ordered, drawing her spear and mounting Scipio.

"Where's P- I...I mean, Nero?" Frank asked.

Their eyes widened when they realized that the son of Vesta didn't respond to the threat.

"Guys!" someone yelled, it was Piper, who was carrying Blue Rose and Red Queen. "He vanished, saying that he knows how to win this!"

She gave the note to Jason, who gasped when he read the note.

"So he just abandoned us?!" a guy from the First Cohort demanded.

"No. Let's just have faith in him." Reyna scolded the legionnaire who said that.

"Fight like hell, everyone!" Mars declared, raising his gigantic sword as the animated armors charged. The ground shook a little as they ran for the border between the Field of Mars, and New Rome. The animated armors slammed right into the shield wall. The four gods blasted the horde with energy before meeting them in conventional combat.

Meanwhile...

'Alcatraz? You have got to be joking.' Percy thought as he drove to Fisherman's Wharf.

'Yes, Perseus. The nearest Devil Arm is located somewhere within it. Once you're on the island, I will continue searching for other Devil Arms near the area.' Sparda's voice replied.

'Hope you're right.'

When he did arrive at the wharf, the son of Vesta didn't wear his cast, as the mortals thought his right arm was covered in black and red bandages and a red glove instead of a demonic right arm with the power to lift a shipping container without any problems. Using his extreme stealth skills, Percy snuck out of the wharf, and went into the water. Despite not being a son of Poseidon anymore, he could still breathe underwater. A while later, he arrived on Alcatraz Island. He snuck in by using short distance teleporting via Yamato.

"Great. I'm trying to find a weapon somewhere within a vintage prison in the middle of a f***ing island! And it was hella cold in the water." the son of Vesta complained softly.

"Uh...bad news, Perseus: the Devil Arm is somewhere under the facility."

'What?!' he thought back.

And so, another painful search begins, which involves him trying to find somewhere that leads to underneath Alcatraz.

Meanwhile...

The battle raged on, with the Romans slowly gaining the upper hand but they were getting a little tired. If the four gods didn't help them, they would have been overwhelmed by now. Jason, Reyna, Piper, and the other centurions continuously inspired the Romans to push back the animated armors, fending them off with a javelin, gladius, revolver, etc.. Suddenly, Diana stopped fighting then said, "I'm gonna go get reinforcements!" before flashing away.

"Oh, come on! Not now!" Apollo complained as he continued to shoot the enemy army.

"I hope it will be worth it." Mars said, striking down another pair of armors with his claymore.

"Push them back!" Jason ordered, swatting an animated armor with Ivlivs's javelin form. In the span of half an hour, the armors were all defeated but another wave flashed in. Only this time, a shower of glowing arrows struck and dismantled much of the armors up front. Shocked, the Romans turned to see Lady Diana along with a group of girls with silver parkas, bows, and arrows, except for a certain daughter of Zeus with her leather jacket, spear, and Aegis.

"Jason?" Thalia gaped.

"Thalia?" he replied, equally shocked.

The two looked at each other, silence reigning the air between them. Phoebe suddenly broke the silence.

"Thalia, you know this...boy?" she asked with disbelief.

"Yes. He's my little brother." the daughter of Zeus replied.

All the Hunters stared at Jason with pure shock, then back to Thalia. It was like this until Diana interrupted.

"Uh...I hate interrupt the family reunion but we're in the middle of a war zone! Hunters, fire!"

Again, they shot the armors with arrows. Jason raised his javelin into the air as lightning rained down on it. Thalia did the same thing, standing beside her brother. A few seconds later, they redirected the lightning at the armors. The animated army exploded like they were hit with the force of an artillery shell and the surviving animated armors were stunned by the force of the blast. Some of the Romans within an earshot temporarily went deaf as the sound of lightning rang into their ears.

"Nice shot, little brother." Thalia remarked.

"Thanks, sis. You too." Jason replied, smiling back.

"Impressive. Charge!" Minerva ordered. The Romans, Hunters, and gods broke their formation and charged the still stunned enemy army with bigger valor.

Back at Alcatraz...

Percy had been wandering the halls of Alcatraz for like an hour.

'There has to be a panel somewhere or a secret passage.' he thought, grumbling as he did. The son of Vesta decided to settle with the stupidest thing he would do as a champion of Minerva: stomp around on the ground floor. He was like this for an hour until he stepped on something beneath one of the cells. It opened a secret tunnel within the room.

"Wow." Percy muttered as he slid into the tunnel. Behind him, the secret door closed. A few bumps, twists and turns later, he ended up in a secret room. It was a dark room with seemingly golden walls with nothing but torches and an old chandelier. In the center was a statue of a man getting stabbed by a sword. What was so eerie was that the sword looked like it wasn't part of the statue. It had a wicked silver blade, a black hilt bearing dark bat wings, and its handle had the look of a coiled wire.

"You found it, Perseus. The Devil Arm within Alcatraz." Sparda said.

"How convenient." he replied.

As Percy approached the sword, however, it began to float into the air.

"Something tells me this isn't going to end so well." the son of Vesta muttered.

"I AM ALASTOR THE THUNDER DEMON! DIE, FOOLISH MORTAL!" the sword screamed.

"I knew it."

Alastor flew and nailed Percy in the abdomen and pinned him to the wall.

"SUBMIT!" it screamed again.

"No thanks!" the demigod replied, pulling out the sword off of his body with Devil Bringer. The sword stopped acting sentient and just said,

"You are worthy."

Alastor suddenly crackled with purple electricity before they disappeared.

"That's one. Where's the next one?" Percy asked the demon inside his head.

"It's in Yosemite National Park."

"Well, crap." the son of Vesta thought back as he sheathed Alastor and broke out of Alcatraz via a secret passage located on the other side of the room that gave him a slide to the water.

Meanwhile...

The enemy army was routed but the Romans remained cautious. That's why Reyna had organized a schedule on which cohorts would be on Savior watch in case there was another attack. Meanwhile, Thalia was inside the principia with Jason, IN PRIVATE.

"I was told Percy was here." she said, making the praetor shiver.

"Yeah...he was here."

"Where is he?"

"Went on a personal quest. Something to do with beating that colossus."

"Can't we Iris Message him? Camp Half-Blood hasn't been the same ever since."

Jason merely chuckled at the Greek camp's name.

"Can't they come up with better names? And...I don't really know where he is."

"What?!"

"He'll come back! He's a tough guy. I'm downright sure nothing's gonna stop him."

Thalia and Jason continued talking and laughing, bonding like siblings to be specific.
