Chasing Aegaeon: A Percy Jackson And The Mortal Instruments Crossover

Percy POV ~ The Emo Weirdos

"Hey, Wise Girl! Behind you!"
Me and Annabeth were walking around one day (which we rarely do since you know, the whole demigod thing with the monsters and all) when suddenly, we got attacked by like three empousa, and a drakon. Right now, we were battling all of them. Honestly, I think that was a bit unfair. Like, if you're gonna send monsters to attack a couple of demigods, you might as well make it so that the battle is fair. Anyway, we were battling these monsters, when suddenly, this squad of people, all dressed in black, (children of Hades?) started fighting and slicing the monsters. They had weird tattoos on them. They also had weird weapons with them. There were these sword things that were glowing, one of them had this whip that wound around her arm like a bracelet. So these weirdos come outta nowhere and start slicing at the monsters. Annabeth and I stare openly with our mouths open as one of them, the one with blond hair, flips onto a monster and cuts its head off. Finally, my Wise Girl realizes that we should probably be fighting these infernal creatures as well. We must have all looked like a great scene from one of those gory movies with everyone fighting evil and all that crap. When we finally get done, the emo weirdos look at us and the blond one says, "thanks for helping out. You don't seem like mundanes, you can see us. What are you?"

"What are we? Don't you mean who are we?" I snapped.

"Nah dude," said the emo kid, "I mean what are you. We are shadowhunters. We are part angel and right now we have a rune on that doesn't allow mundanes to see us. Obviously you can so you can't be a mundane, so what are you?"

"First of all, what the hell is a mundane? Second, we are demigods. Half god, half mortal. Annabeth, my girlfriend, is a daughter of Athena meaning Athena is her mom. I am a son of Poseidon meaning he is my dad."

"That's really cool! So a mundane is someone non-magic. So basically like a muggle. By the way, I'm Clary, the dude who so rudely asked what you were is Jace, my boyfriend, the two black haired shadowhunters are Alec and Isabelle, they're siblings," said the red haired one. That's when my brain exploded. That was a lot for me to process. To be fair, these shadowhunters just kinda came and started fighting monsters with us out of nowhere so I deserve to have my brain muddled. 

After a couple minutes of awkward silence, Annabeth asked, "What were you doing fighting our monsters?"

"You call them monsters? We call them demons and lately there have been more and more of them wrecking stuff," said the one called Alec. That was weird, 'cause for us, they seemed kinda on the down low for the past week. There must be different shadowhunter demons and they just happened to see us and our monsters. That was all my brain could take for today, so I told Annabeth (she understood my problem) and we said our goodbyes and we left. After that, Annabeth and I both agreed that we deserved Olive Garden for lunch.
