Author's note: Sorry for not updating for so long. I had a chapter in mind but decided that it wasn't that great so decided to re-start. Some of you might have noticed I wrote that Nico had something to ask Will but in the next chapter it's Will that asks Nico to marry him. I just noticed that mistake and fixed it. I'm also going to be going back to other chapters and fixing spelling and grammar mistakes so if you want to go back and read those you can but I am not going to change any of the plot so don't feel like you have to. Finally, I just want to say I do not support J.K. Rowling anymore and do not believe what she is saying is true. Trans women are women and trans men are men. If you still support her and believe she isn't doing anything wrong please unfollow me. I don't care if you are going to still buy official Harry Potter merch as long as you don't agree with her. I understand if you don't want to be apart of the Harry Potter fandom anymore because of J.K. Rowling and I will not be offended if you stop reading my fanfiction because of that. For me personally, I'm not going to let her ruin Harry Potter for me, I get that that is not the same for everyone. At least Rick Riordan isn't a transphobe. Also, if you haven't read the Cassandra Clare books I highly recommended it. Not only does it have an amazing plot but it also includes LGBTQ characters and the author is not a TERF. I hope you enjoy the chapter.

Nico P.O.V

As soon as Potter spoke everyone froze. Us demigods looked at each other and immediately started exiting the room, grabbing Potter on our way. As we were leaving we heard everyone start to whisper. They had heard us being called demigods. The pure-bloods and some half-bloods were confused but anyone who went to muggle school at one point knew what a demi-god was from learning Greek Mythology at their school. What they didn't know was that we were real.

"What was that?"

"What's happening to me?"

"What do we do about the mortals?"

"What do you mean demigod?"

Everyone was blurting out questions and talking at once.

"Shut up!" Annabeth yelled, everyone immediately obeyed, "One thing at a time, first, everything you learned in DADA class is real. Second, it seems as if you are possessed, by who I'm not sure but I have a theory," She turned to the demigods, "We should IM Chiron, it would be hard to use the mist on all the mortals, and if something like this happens again we can't keep making them forget. Besides, they're wizards, and if he's being possessed by who I think he is we will need help."

"That's great and all but who do you think is possessing him?" Jason asked.

Annabeth looked at Percy and Nico as she spoke, "Tartarus," as soon as she spoke the word she shivered, Percy's eyes widened and he looked like he was trying not to have a panic attack as he walked up to Annabeth and they hugged, and Will tighten his hold on Nico as Nico looked like he was going into shock. The other demigods looked concerned for them, and they were worried about everyone.

The Hogwarts demigods could tell Harry was still very confused so Piper him to the side to explain in further detail, as they did not think Nico, Percy, and Annabeth would want to talk about their journey in Tartarus.

Just then Coach Hedge came in, "Sorry I'm late guys, I couldn't leave because it would look suspicious." They filled him in on the plan.

Thalia IMed Chiron to explain the situation. After an hour of talking, they came up with a plan. At Breakfast tomorrow they would explain everything to the mortals. They would continue to learn how to fight and if it came down to it would have a choice to fight or not.

"One more question, Malfoy, if you were undercover this whole time why did you have to act like a jerk? Couldn't you just have befriended me? And Mione, why did you lead Ron on? He's really upset that you were cheating on him," Harry asked?

Draco answered, "We were all given very specific instructions for how we should act, who should be our friends, who we should date, and pretty much every action we did. Also, it wasn't hard to hate you, you're very ignorant and annoying."

Hermione decided to add, "I really did love Ron," Draco looked at her shocked," but as a brother. Sure I was just following orders but how can you not get close to someone after spending 7 years with them?"

"This is all lovely and everything but we should get back to the dorm."

The next morning, students were given specific instructions to be in the great hall by 6:30. As the students sat down, Dumbledore walked up to the podium.

"Good morning Hogwarts, many of you are making rumors about last night's events. Everything will be explained in due time. Can our exchange students please come up here?"

Taking their cue, all the demigods walked up. Percy started speaking, "Alright, everything you learn in DADA is real." As soon as he said this, chaos broke out.

"Liar!" "Prove it," and so on.

"SILENCE!," Dumbledore yelled.

Annabeth stepped forward, "Well done seaweed brain," she said sarcastically, So basically we are the god's kids, I'm Annabeth daughter of Athena."

"I'm Percy, son of Poseidon."

"Nico, son of Hades."

"My name is Will, I'm the son of Apollo."

"I'm Piper, daughter of Aphrodite."

"Leo and I'm the son of Hephestus."

"Thalia, daughter of Zeus."

"Frank, son of Mars."

"Hazel, daughter of Pluto."

"I am Jason the son of Jupiter."

"I'm the real Calypso, all the myths are true. I'm no longer immortal though."

Once all the introductions were done, Ron stood up, "You're clearly lying, prove it." The demigods smirked at this.

Leo spoke first, "Your wish is our command." All at the same time, Leo burst into flames, Frank turned into a hawk, Percy lifted up water from people glasses, Jason flew, Nico and Draco summoned some skeletons, Hazel summoned some gems, Neville grew plants, and Thalia struck lightning. The demigods without powers stood off to the side smirking.

Everyone in the Great Hall was speechless. Some still looked doubtful but most people were convinced.

"Everyone will continue to learn self-defense in DADA. We are on the brink of another war. If it does come to a war, years 4 and up will be allowed to fight if they want. No one will be forced through. Also, other demigods will be around, so if you need help with anything fighting related or monster related, anyone in an orange Camp Half-Blood t-shirt or a Purple SPQR t-shirt you can ask.

Author's note: Sorry It's short. I'll try to update more but school is keeping me busy. Stay home and stay safe.
