Welp here's the next update. Again, crossing over with Magnus Chase after the Kane Chronicles crossover last chapter.

I hope you guys enjoy! Please review.

Percy Jackson and the Master of Magic

When Percy and Annabeth are asked to stop a monster by Reyna, they think it will be an easy last quest before retirement. But when the mission goes horribly wrong, Percy Jackson finds out just what kind of monster he could become.

Disclaimer: I don't own Percy Jackson or its characters, Rick Riordan does.

Reminder: This story is AU as of The Burning Maze. In this AU, it's been two years, and the defeat of Nero, Commodus and Caligula will remain mysterious save for the fact that Percy and Annabeth participated in the defense of Camp Jupiter. I kinda wanna stick away from Trials of Apollo for the most part, since this is my thing.

Chapter 17: Evil Ways (Justice Mix)

…

Kronos walked through the Pentagon hallways as if he owned it. No one gave him, with his trident hanging on his back and molten gold eyes, a second glance. Kronos smiled. The arrogance of humanity, which was once annoying to him, was now a very attractive trait.

He knocked on the door of a General John Allen and allowed himself inside.

General Allen jumped out of his seat. "Who the hell-"

"Enough!" Kronos interjected. "I do not have the time for this!" He pushed the General back into his seat with telekinesis and snapped his fingers. All noises, such as the sound of feet falling on the hallway floor, became undetectable.

"Who- who are you?" General Allen asked shakenly.

"My name is Kronos." Kronos answered. "You can call me your benefactor. I'm the one who removed the veil and let you mortals see."

"Us mortals?" General Allen asked. "What are you?"

"I am a Titan." Kronos answered. "And I need your assistance, just as you need mine."

"Why do we need your help?" General Allen challenged.

"Because of your little problem tracking the people who keep escaping you, on Long Island and in the Bay Area."

"How did you know about that?" General Allen asked.

"Because I am a Titan." Kronos responded. "I foresaw that they would escape you using help from a group known as the Amazons, who have infiltrated your agency. I also know where these escapees will be tomorrow."

"Really?" General Allen asked.

"Yes." Kronos said. "And I'll help you capture them."

"And what do you get in return from us?" General Allen asked.

"Your help in ushering humanity into a new age of refinement and expansion." Kronos responded. "With my own gentle guidance, of course."

…

Annabeth has forgotten how much she hated Boston. She was walking through the park and sat on a bridge where she first held a conversation with Magnus Chase. All she could think about was wistful memories with Percy and bad memories with her evil uncle.

"Annabeth?" Magnus called. He had a sword hidden in his bag.

Annabeth cracked a smile. "Magnus." She said, happy for the first time since she came back. She hugged her cousin, but he wasn't really hugging her back. His face was drawn, with bags under her eyes.

"Hey." He muttered uncomfortably.

"Are you okay?" She asked. He was kind of scaring her. What had she done to hurt him? Or, oh gods, what had Percy done while he was trying to bring her back?

"I'm, uh fine." Magnus responded. There was silence, and Annabeth now knew for certain that something awful had happened, and he wasn't quite sure whether or not to talk about it.

"Is that Jack?" Annabeth asked, desperate to change the subject. "The talking sword. That is his name, right?"

"Yeah, that's his name." Magnus answered slowly, as if thinking about every word. "He's back at Valhalla. Alex is keeping him company."

"Magnus, I don't know what happened," Annabeth started. "But you kn-"

"What do you want?" Magnus asked exasperatedly. "I know this can't be a courtesy call, and since you're obviously not dead anymore, I can only assume you need my help with some world-ending catastrophe."

Annabeth was taken aback. Never had her cousin been so openly aggressive with her.

"Annabeth?" Magnus asked. His eyes were downcast.

"Its, um, its Percy." Annabeth said. "He's been possessed by the Titan Kronos for a while now. Kronos is the one behind the spell that removed the Mist, or the um, the glamoure, and we have reason to believe that he can undo it. We have a way to force him too, but we need to know for sure, and someone told us that Odin would know what to do."

Magnus rolled his eyes. "Right, Percy, causing problems. Who could've guessed?"

"Magnus, what did Percy-"

"He killed someone I cared about." Magnus said. "To bring you back." Magnus nodded his head.

"Yeah." Magnus said. "I get it now. No one is more important to you and Percy than each other. Damn the rest of us who have to pay the consequences for your mistakes."

Annabeth reached for Magnus' hand. "Magnus-" She started, but Magnus snatched his hand back and walked away.

"No!" Magnus shouted. "I'm not interested. You, Percy, all of the others, leave us the hell alone. We're done helping."

"Magnus?" Annabeth asked, tears falling.

But Magnus walked away. And he didn't turn back.

"Men these days." A voice said derisively from behind her. Annabeth turned to see a large troll standing behind her. The troll grinned.

"How do you do?" The troll asked. "Do people still say that?"

Annabeth stared, confused because the sparse park walkers seemed to not notice the giant troll.

"If it is not too offensive, why do you weep, young lady?" The troll asked.

"My um, my cousin, he won't help me." Annabeth answered, not understanding why she seemed to trust this giant so much.

"Why?" The troll asked, curiosity filling his face. One of his eyes never seemed to blink. It was a strange detail Annabeth could not help but notice.

"Because my, um, my boyfriend, I think he may have hurt my cousin." Annabeth said. "I've been gone for a little while and I'm trying to find my boyfriend because he's…um, he's been taken."

The troll nodded. "Yes, taken by whom?"

Annabeth hesitated. So many lies in so many days. Annabeth was tired of it, and the troll, for some odd reason, seemed completely trustworthy.

"He's been possessed," Annabeth said. "By a Titan, who just crippled the planet and seems determined to deep fry it."

"Is he the one responsible for the Fall?" The troll asked curiously.

"Yes." Annabeth said. "We think that he might also be able to reverse it, but, um…"

"Oh, he can." The troll said with confidence. "I have an entire PowerPoint presentation explaining how. It's just a simple incantation. Elementary, really. All it needs is his signature, his power. It doesn't even necessarily need to be him. If he is occupying the host, the host will do just fine."

Annabeth was shocked. This troll was voicing facts about magic like nothing.

"Who are you?" demanded Annabeth.

"I thought you were looking for me?" The troll asked. "I am Odin, the king of Asgard, and I am always pleased to meet someone as nice as you, young lady."

"How come no one-" Annabeth gestured to the pedestrians around them. Odin seemed confused for a second, but then shook his head, smiling, as if he understood something.

"Oh, how come the mortals can't see me?" Odin asked. Annabeth nodded. "Well, there are more types of concealing magic than just glamour, or the Mist, as you call it. I'm simply exercising one such method. I sense you have more important questions besides the reason why mortals can't see a giant in the park."

Annabeth hesitated, then licked her lisp. "So, do you know the spell that can fix all of this?"

"I do." Odin agreed, smiling.

"Can you help us?" Annabeth asked.

Odin nodded his head slowly. "I suppose I could, and I suppose I will. Besides your honesty and politeness, it is within my own self-interests. After all, I would love to be restored to full power. So many presentation opportunities, wasted because of my irritating newfound need to sleep."

Annabeth smiled. Maybe things were going to be alright after all.

"But." Odin continued, his smile freezing Annabeth cold. "Your boyfriend, he took a Valkyrie from me. One of my favorites, in his mad attempt to resurrect you. That can't sit by. So, if he returns from his possession, somehow alive, he must face consequences. I understand he wasn't in a very good state of mind, but, still."

Annabeth sighed. It seemed like no matter what good her and Percy did, there would always be another problem for them to face later on down the road.

"Do we have an arrangement?" Odin asked tentatively, his face an unreadable mask.

Annabeth hesitated. Then she bowed her head, not bothering to try and stop the tears. "Yes, we have a deal." She agreed miserably, knowing that the lives Kronos would take was more important to avoid than Percy's demise.

"Good." Odin said, seeming to relax a bit. "I am glad. I know that could not have been an easy decision. I will even sweeten the deal some more. Should things come to a head, I pledge my troops of Valkyrie and Einherji to the battle against Kronos."

"Thank you." Annabeth answered hollowly.

"You are most welcome." Odin answered amiably, smiling away and ignoring Annabeth's anguish.

…

An hour later, Annabeth pulled out her new burner phone and called Piper.

"Yeah." Annabeth said. "He gave me the spell. We have everything we need to beat Kronos now. Yeah, I'm on my way back. I have an idea as to how we can trap him first." There was a pause, and an indiscernible humming from the other end.

"Yeah, I'm fine, Piper." Annabeth lied. "Yeah, I'll call when I'm back in New York. See you all soon." Annabeth hung up the call before any more attention could be given to her, and she stared at the background picture she had set. It was a picture Chiron had taken of the two of them. She stared at Percy's tanned skin, his sea green eyes and windswept black hair.

She sobbed silently, worrying about their child having to grow up in a world without his father.
