PJO/HP crossover: what will happen?

Now this is what I mean

Reyna's p.o.v

I had been flashed out of Hogwarts for the monthly Senate Meeting. I was the only one who got out as Frank had stepped down from Praetorship and we had tow wait till the Feast of Fortuna. As I was handling the Senate an Iris Message appeared in front of me.

"Hey Rey" Jason brightly said.

" Jason Grace, you better give me a good reason as to why you have called me on a Sunday. You know that we have our monthly Senate Meetings today, or did you forget about it in your time with the Graceus (I hope i spelt it correct)" I growled.

"Woah Rey. What's got you in such a mood. I thought Octavian died in the war." He joked.

"Just tell me what happened" I snapped.

"Okay, jeez. So basically we've got another war on our hands." He replied

"Call me after an hour. It seems like you are forgetting our whole culture Jason. The whole policy of no disturbance while a meeting" I replied and swept my hand through the Mist.

I know what you may be thinking, 'why are you being so rude to Jason?' Well I was not quite over his betrayal. It didn't bother me that he got a new girlfriend. I mean okay he lost his memory and he didn't remember- well us. But couldn't he at least be a man and tell me that. When he came back to Camp Jupiter he didn't even talk to me or anything. Even after revelling through the Mare Nostrum he did not say so much as a 'Thank You'. So now I decide I would give him the same treatment.

"  So as we heard from Grace, we have another war. We will win this war and show these enemies that they should not even dare look at the Roman Empire with the hopes of conquering it. We will once more crush our enemies. I will contact Rachel and see if she has any prophecies. All Centurions wait back we need to discuss this. Dismiss" I ordered and saw as all the people left the Senate House.

"Any cohort leaders have any ideas or strategies" I asked and Bobby from the Third spoke up

"Why don't you ask Jason who the enemies are. With that information we will be able to plan something" he told.

As hard as it was for me, I had to agree to do so for the welfare of Rome.

"Oh Fleecy do me a solid, show me Jason Grace" the call connected and the scene filled me with horror. Out there all of the Seven and Nico,Thalia, Calypso and all the other demigods sent were fighting a never ending army of monsters.

"PERCY" I shouted as I saw a monster creep up on him. He quickly turned back and slashed it. I quickly turned towards the centurion of the First, who was a child of Trivia.

"Quick, transport me to the battlefield " I commanded.

"But Praetor..." She protested

"No buts, just do as I say" I ordered in a strong voice. She gave out a sigh and grasped my hand, closed her eyes and then a sensation came over me. It was like I was being squished into a small pipe. When I opened my eyes I saw trees all around me.

"The battlefield is just out of this forest. It will only take you five minutes. You just need to walk in front and then you will see it" Phoebe said.

"And if I run?" I asked

"Probably two minutes" she replied

Without waiting for another second I sprinted ahead. True to her word in a few minutes I arrived there. The amount of monsters was shocking. It was surprising that the demigods were still alive. I took out my daggers and charged ahead. My first monster was a werewolf from a stray pack that was coming onto Piper from behind while she was battling three hell hounds.

"Reyna, what are you doing here?"  She asked. Well ore like exclaimed.

"Saving your lives as for now" I replied.

As I was killing the monster only three words were going on in my head 'stab, duck, sweep'. After a few minutes on,y a few empousi were left and seeing as they would clearly die they left. Before that they said

"She will have you as a sacrifice, Mighty Praetor" she mocked before she vanished.

Before I could comprehend anything I was being crushed by someone.

"Thank god you came Reyna. We would've died without you"

"So well now you owe me two" I said and pushed him of.

"Come on Rey you know you won't ask me for anything" he replied with a cheeky grin

"Sure, Percy keep on thinking like that and it may come true one day" I said with a small smile. Out of all the Seven, Percy was probably the only one I felt so comfortable with. He was like my elder brother.

"Mmmh mmmh " Nico fake coughed, and opened his arms as if expecting a hug. I just pat his back. He gave a fake look of hurt and turned away.

"So Jason who is our enemy this time" I asked Jason.

"I think Gaea has teamed up with Voldemort" he replied

"The Flight of Death " I replied

"What?" Jason spluttered

"Honestly Jason, didn't I tell you five times. Voldemort means Flight of Death in French" Piper said in a tone that just said she couldn't believe this. Well I could believe this, Jason wasn't one could go through long things in full concentration.

"How do you know about Earth waking again" I asked

"Well, I thought that recent increase in monster activity was her doing" he said sheepishly as he scratched the back of his neck.

"Well, you stupid boy did you forget that we put her to sleep, it will probably take a few hundred years or so for her to wake up again" I scolded.

" So who do you think it is" he asked.

"Another primordial I say, probably Lady Night" I said

"Ny...?" Annabeth asked.

"Names have powers, don't say Her name" I quickly interjected.

As we were discussing these thing we heard someone say

"Oh my God. Haven't you dunderheads heard of the saying 'fear of the name increases the fear'" the voice mocked.

When we turned  we saw...

Hey guys so here is the new chapter. I hope you'll like it. Constructive criticism is appreciated. I wanted a favour please,please forget the prophecy from DADA class. I wanted to ask do you want Thalico or not. Voting on this is on till next month so I can plan the chapter with or without them. Sorry for the wait
