Third Person:
The demigods burst into Dumbledore's office. "We're done," Percy said.
Dumbledore looked up, surprised. "You're much quicker than I thought. It has only been half an hour."
Percy asked, "How much time until the battle?"
His expression became much more serious. "The battle will be happening today. It appears that they are preparing to head to Hogwarts. They will be here in two hours."
Percy looked extremely worried. "Wait a moment. I have to talk to Chaos."
He teleported to the throne room. "Father, the primordials, the titans, and Voldemort are heading to Hogwarts already!" He panicked.
"Yes, I know. I also have something to tell you. Information from Nyx. She has barely escaped from the titan's palace."
"They've discovered her?"
"Yes. The titans, before, were cast into the pit. After Harry escaped from Voldemort last year, he was wandering around and met Kronos. They agreed to form an alliance, and Kronos told Voldemort to put a spell on the primordials. The Imperius Curse, whatever that is. They only put it on the currently rising ones since they think that the curse is easier to perform on them. They don't see us often and therefore don't have such a stable connection with us. That makes it easier for Voldemort to control them. Nyx overheard this and escaped quickly before they could find and capture her.
"That's a lot of overwhelming information. So our goal is to help the rising primordials break free of the Imperius Curse, help the wizards defeat Voldemort, and get the Titans back to Tartarus. Correct?"
"Yes. A very good summary. But there is still two urgent things that you need to do: Tell the wizards who you really are. Tell them about demigods. Otherwise, they will not trust you and obviously will not fight by your side. And remember to call for demigod reinforcements."
Percy nodded his head and teleported back to Dumbledore's office. He then described to Dumbledore and the other demigods everything.
He then teleported to Camp Half-Blood. "We need reinforcements." He panted. "Right now. They are coming and will be in Hogwarts in three hours."
"My, my, Percy, it's been two months since we've seen you. You all right?"
"Yeah, of course."
Chiron smiled.
Percy teleported back to Dumbledore's office. "How should we introduce ourselves?" He asked, mostly to himself.
"Say your name, your godly parent, your titles, and powers."
They groaned, getting a piece of paper to write everything down. They spent the next hour doing that, and finally, they were happy with their results. The last hour was spent thinking about ways to get some particular primordials out of their trance.
Right before Voldemort, the primordials, and the titans arrived, Dumbledore gathered everyone at the Great Hall. He yelled over the students, "Voldemort and some powerful entities will be coming to Hogwarts in a few minutes. Be prepared. Reinforcements will arrive."
The next moment, an evil voice echoed through the hall. Voldemort was speaking to everyone. "Bring me Harry Potter and Percy Jackson, and you will all be spared. Bring them to me before the next hour." He commanded.
Whispers of scared voices were scattered throughout the Great Hall. "Well, it's a good time to reveal, isn't it?" The demigods seemed to ask each other and agree.
"...But never fear, we have some powerful demigods to help us defeat the entities."
His eyes traveled to the group of demigods. They scooted their chairs slowly, creating a cacophonous scratching noise, loud and clear in the absolutely silent Great Hall. They walked up to the stadium Dumbledore created before. Everyone was looking at them.
