And here comes the battle at CHB. Please don't hate it too much. Like I've been saying before, fight scenes aren't really my thing. It's mostly cute scenes and humorous stuff so yeah.

DISCLAIMER: I DON'T OWN MIRACULOUS LADYBUG OR PERCY JACKSON AND THE OLYMPIANS/HEROES OF OLYMPUS! Cause let's face it, if I did, it'd be absolute bullsh•t. And take three (or like seven, you never know) years for each book to come out.

Annabeth's POV:

"Thanks Malcom, we'll take it from here." With that, we all ran to the Big House where everyone else was. Malcom took Nico and Hazel to the infirmary. I opened the door and the room went quite.

"I received information from Malcom on where certain cabins are." I said once everyone was attentive. "Just how many monsters do we estimate there to be?"

"A hundred and fifty at least from what we've seen." Travis answered. "Nothing's coming from the sea so far."

"Are there any demigods alongside them?" Percy asked. Travis shook his head. "Good." Percy said. "Have any demigods travelled back from their schools?"

"So far no one." Connor answered.

"Are some of our best fighters here at least?" I asked. I hoped Clarisse didn't leave, we'll need her for this.

"Clarisse is here if that's what you want to know." Lou answered. "Most of the Hephaestus kids are here as well, though we made sure Harley is only setting traps. Though if he has to fight, we won't stop him."

"Wait I thought all you Hecate kids were distracting the enemies." Piper said.

"Most of us are doing that." She replied. I nodded and shared a look with Percy.

"Is there anything else we need to know?" I asked. "Injured demigods? Has anything worse happened?" They all got the hidden message behind my words. Has anybody died?

They all shook their heads and I nodded in relief. "What about the Romans? Does Reyna know about this attack? Is there one happening there?"

"I Iris Messaged the Romans." Chiron said. "Reyna informed me that here have been no attacks, and that they are sending a group here to help us. Jason included." Chiron added before Piper could ask. She nodded and closed her mouth. "Some will be travelling by eagle, and there others will be driving."

"I'm assuming we're talking about the Romans?" Nico asked walking in.

"You good to fight?" Percy asked.

"I'm always good to fight."

"Nico!" Will yelled coming up behind him. "You should be resting right now. That was a huge jump and would be hard even with you and Hazel working together!"

"I'm fine." Nico insisted. "I've shadow travelled plenty of times, and the unicorn drought helps me as well as ambrosia and nectar."

"Will." I said. "We need all the demigods we can get for this battle, if Nico says he's okay to fight we'll let him. Don't worry, if anyone notices that Nico is exhausting himself, they'll take him to the infirmary." I looked at everyone else in the room. "Right guys?" They nodded.

Nico rolled his eyes. "Need I remind you that I am older than everyone in the room, besides Chiron? I don't need to be babied by everyone."

I narrowed my eyes at him. "If Will and I say you need to be looked after by everyone here, you will not question us or whinge about it. Understand?"

He twitched a little bit, whether out of slight fear or annoyance I wasn't sure. "Fine." He sighed. I nodded. "Good." I turned and looked at Percy, signalling for him to take the lead.

"Okay, Travis take one of your siblings, not Connor, with you and go check on the scouts, come back here immediately even if they only spot a few monsters. Connor, go with another sibling and check on those at the barrier if they need more people, one of you come back while the other stays and fights, if not, then both of you come back. Will, since you're here go check on those in the woods with Piper. Same instructions I gave to those two for you guys. Everyone else, try and get in contact with the demigods in school. Try not to use IMs since they'll probably be around mortals. Go." Everyone else scattered except for Nico, Chiron, Percy and I.

He sighed. "Why'd there have to be an attack now? We literally just told Adrien about him being a demigod! I can't believe Piper had to charmspeak him to forget that!"

"I know Perce, I know." I looked outside the window. It beginning to darken outside. "We'll have to be very careful. Night is falling, and no one knows when Nyx will use her powers against us. Go to the beach, you might sense something the others won't see." He nodded and gave me a small kiss on the lips. "Don't do anything stupid without me Seaweed Brain." I warned before he left. He chuckled then jogged to the beach.

"Nico, go check on Hazel, I can tell you want to." I said looking at him. He smiled slightly then went out to make sure his sister was okay.

"It'll take at least an hour for the Romans to get here." Chiron said. "I hope we'll be able to hold them off until they come."

"Me too." I replied.

"You should go and help out those at the barrier. I'm sure Thalia would fight better once she knows you're okay. When the others come back I'll give them their orders. Don't forget to tell us when the Romans arrive."

"Of course. See you later Chiron." I said, before running to the barrier.

Percy's POV:

As I made my way to the beach I passed Travis and Jen, one of his siblings. "Anything?" I asked. They shook their heads.

"No." Jen replied. "No one's seen anything. But we all have a feeling something's there."

"That's why Annabeth sent me." I replied. "Well, see ya. Go back to the Big House, guys don't fight unless we definitely need you to."

"Yeah yeah Perce." Travis said rolling his eyes. "Take care!" Without the two of them went off and I continued my way to the beach."

"Percy!" A voice exclaimed once I got there. I looked around and noticed Kayla up in the trees waving at me.

"Anything yet?" I asked. "Also, I thought the Apollo kid were either fighting or at the infirmary."

"We can't see anything, but something eels wring. And we can shoot some monsters from here if we need to." She explained. I nodded then walked into the water. At first I felt nothing and the water felt normal. Then it started to feel heavier and darker. "What the Hades?" I murmured. I knelt down in the sand and put my hands in the water, thinking it was just my imagination. It wasn't.

"Guys, get away from here." I said standing up quickly and moving away from the water.

"Wha-"

"Go now!" I yelled. The went off, just as the water rose up in a dark giant wave. Keto and Phorcys right on top of it. "One of you warn Annabeth and Chiron!" I yelled to their retreating figures. "What are you doing here?" I questioned.

"Now, now Perseus." Phorcys, grinning manically. "We just wanted to meet you again. And Nyx told us to bring one of her, friends here." Immediately searched the water for whatever monster Nyx must of sent. When I found it, or rather her my jaw slackened. "No." I said. "No I refuse to fight her!"

"Ooh, so you do recognise this little Huntress." Keto stated smirking down at me. "Little Zoë Nightshade here now serves our mistress. And she wants you to suffer before she finally kills you once and for all."

Zoë's constellation form ran towards me, weapons gleaming. I dodged all of her attacks, not wanting to hurt her. And she was just a constellation now, she couldn't hurt me. Well, that's what I thought.

I barely dodged the attack she aimed at my throat and I received a thin cut near my collar bone. A few drips of blood came out. I looked at her, and she was ready to attack once more, and I quickly made up my mind.

I uncapped Riptide and she (A/N: Yes, ¡WARNING-SPOILERS FOR MAGNUS CHASE SHIP OF THE DEAD IF YOU HAVEN'T READ IT YET¡ Riptide is actually a girl) blocked Zoë's attack just on time.

"Zoë!" I exclaimed. Trying to find a sign that she wasn't under Nyx's complete control. "Come on don't do this! You're going against Artemis!"

Nothing happened and she slashed at me again with her hunting knives. If she could hurt me in that form, that means I can hurt her as well. I thought. It was then a remembered there was water next to me. I forgot I was on a beach. I put my left hand towards the water, trying to get something so I could distract her and get Thalia here. She would do a better job at fighting Zoë than me, I admitted to myself. I was only able to control a stream of water rose and I used it to surround her legs and arms trying to keep her from moving. However since she was made of stars, she separated herself and avoided the water.

I groaned inwardly and decided to use a full wave to take her out for a little while. She stayed where she was, and opted to use her bow and arrows instead of her knives. I put majority of my focus on the water, which refused to obey me. I glanced at Keto and Phorcys and were grinning down at me, probably laughing at my failure. She let the arrow fly and I still couldn't control the water. But something else did. A gigantic wave rose up behind the two monsters.

Another arrow knocked Zoë's one away from me. I turned and saw both Thalia and Annabeth near the trees. "Percy are you doing that?" Annabeth asked staring in awe at the tidal wave. I shook my head. "I was only able to control a small stream of water. Whoever is doing that, isn't me."

"Is it your dad?!" Thalia yelled as she engaged in battle with the former Lieutenant of the Hunt.

"The gods can't help us in this battle." Annabeth said. "Who could it b-" She stopped mid sentence as the wave grew bigger and slammed into Keto and Phorcys, making its way towards us. I closed me eyes trying to keep the water away from me, Annabeth and Thalia. I found that I couldn't control the water again, but realised I didn't have to. The water swept up all our enemies and carried them all out to sea.

After a long time the wave stopped and demigods began to surround us at the beach.

"Prissy did you do that?" Clarisse exclaimed, trying and failing to hide her awe. I inwardly smirked at her reaction, and shook my head. "It wasn't me, and there's no way it could be my dad."

"That's because it was me." A woman said. All of us turned to the water, where a woman began to transform from a water form to flesh and (probably) blood.

"Who are you?" Annabeth questioned. "And why did you help us? Not that I'm ungrateful or anything, but why?"

"My name is Thalassa. I am one of the older Goddesses of the Sea."

If you guys are confused, this is the first part of the battle okay. The Romans aren't there yet and they haven't been transported back to their hotel room. Sorry, but you guys will have to wait till next week to find out what happens next.
