Percy and Nico Undercover at Hogwarts

Chapter One

Percy's POV

When the Giant had ended, only three of the seven heroes of the prophecy had made it out alive.

Frank had been the one to close the doors, getting trapped on the other side.

Jason had ended up sacrificing himself so he could save Piper.

Annabeth had died in the Tartarus after her body had been tortured to the point that she couldn't survive.

Hazel's soul had been sent back to the Underworld only hours after the doors were closed.

The camp was rebuilding itself, but it was taking a lot longer since they had lost their number one architect.

It had taken me six months to finally moved on from the loss of everyone who had died. I would've still been locked in my cabin grieving if Nico hadn't snuck me into the Underworld and showed me how happy everyone was in Elysium.

Annabeth had told me that she wants me to be happy, and that I deserve to be happy. She told me that I was never meant to be with her.

She said that Aphrodite's had come to her in a dream while she was in the Tartarus saying that she was just a guide for me so I could do all the things that I did.

When I asked her what that meant, she said, "If it wasn't for me, you wouldn't've giving up immortality, which you needed to do. If you would've accepted it, you wouldn't have been able to be one of the heroes of the prophecy and you wouldn't've able to help out during the war because gods can't interfere with mortal affairs."

Once she had seen that I had finally understood her, she gave me a hug goodbye and told me not to visit her again until I died myself, and then Nico and I shadow traveled back to camp.

We had gotten 10 months of peace before Nico and I were summoned to Olympus.

"Why are we here?" I asked as the two of us stood in the gods throne room.

"We need your help," Zeus started out but Nico cut him off before he could say anything else.

"We've helped you people enough and we've all lost a lot doing it."

"Hush!" Zeus yelled. "We're sending you two on a quest to help save another world."

"What other world?" I asked and Hades started explaining.

"We, ourselves, cannot tell you. But we're sending you to London to figure it out for yourself."

"Why can't you tell us?" I asked and Zeus shrugged.

"It's against the natural law of things for us to even interfere with this, but since their world is in grave danger, you two need to help them."

"Help who?" Nico asked.

"We are going to tell you your quest, but not give you a prophecy, because I'm sure you guys have had enough of those," Dad said, completely ignoring Nico's question.

"Bu-." I was cut off.

"It will not be long until you run into those who need your help," Apollo started. "They will be able to see through the mist, but they cannot find out what you two are unless it's absolutely necessary. The headmaster knows what you are and that your coming, so go to him is you need anything. The people your helping are in their fourth year. Nico, you are the perfect age, and Percy, I'm sorry, but we're making you fifteen," he said and Zeus waved his hand and I looked at myself.

No much changed. I shrunk a few inches and I lost some of my muscle, but that was it.

"Now, it's time for you two to leave," Zeus said, and with another wave of his hand, we were out of the throne room and in the streets of London. 

Nico's POV

Naturally, the two of us had no idea what we were doing, so after walking around for twenty minutes talking about how the gods aren't helpful, we run into a group of around 10 empusas.

I pulled out my Stygian Iron sword out of the shadows like my father had taught me and Percy pulled out Riptide and the two of us charged the monsters.

Mortals started screaming and running away, and after about five minutes, Percy let out a scream and I saw him fall to the ground. I ran over to him and stood over him as I fought off the she-demons and after a few moments, these three teenagers run up to us pointing sticks at the monsters.

"Get out of here!" I yelled, but the stayed anyways.

"Petrificus Totalus!" they yelled and three different monsters went stiff and then fell to the ground, unable to move.

I quickly finished off the rest of the empusas and then walked over to the three monsters on the ground and stabbed each of them in turn before running over to Percy.

"Percy, are you okay?" I asked and Percy nodded. "That was a stupid question, you're not okay," I told him and I put pressure on the slash that was across his chest so I could stop his bleeding.

"Do you have any Ambrosia or Nectar?" Percy asked and I shook my head.

"They didn't give us time to pack anything. They just sent us here," I said and Percy groaned in pain.

"Is he okay?" a British accent called as the three people who appeared earlier ran over to us.

"Go away," I said rudely and Percy slapped my arm.

"They might be the people we were sent here to help," he told me quietly. "Apollo said it wouldn't be long until we ran into them." Then he turned to the three people. "No, I'm not okay."

"We should take him to the Burrow," the ginger said. "Mum will know what to do."

"Are you sure?" the other boys asked and the girl slapped his arm.

"Of course he's sure. The poor lad is bleeding out!" she yelled and the she crouched down by Percy. "Don't worry, we're going to help him," she said to me as she put he hand on Percy arm and my shoulder. Then, we were sucked into the darkness.
