Thalia POV

A talking hat…seriously? Well in short, the hat relived some of my greatest achievements and failures! So, he put me in Gryffindor, the house of the brave blah, blah, blah. Who cares? Anyways, we exited the Great Hall and followed the Harry Potter dude out. He came to this giant portrait of a fat lady singing and said some sort of password, and the door opened.

The common room was all red and gold with lions everywhere; I asked some bushy-haired friend of Harry's where the dorms are. She pointed to the right side of the common room and I went up. Bushy haired girl followed me.

"So where are you from?" she asked me.

"New York." I replied.

"What do you do in your school?"

"More Physical training than magic training."

"Did you like the ceiling on the great hall?"

"Yeah, I liked it." It was cool, seriously, but not as good as Zeus's sky temple Annabeth designed in Olympus.

"What's you family like?" she asked.

"My mom is dead and my dad never visits," I said, hey Zeus has good reasons not to visit me, but I do wish he was here a few times...Not every day. I like Artemis better.

"What is your favorite professor?"

"Severus." Hey, Nico's brother was cool.

"Why?"

"He is my cousin."

"Okay…What-"
"Wow…I'm really tired, can I go to sleep?" This conversation was getting dangerous, Chiron said not to tell the wizards. I got in bed and lay down, almost immediately, I fell asleep.

My dreams were as scary as ever. It started with some bald guy with no nose sitting at a desk, tapping his fingers.

"Well, Malfoy, what is it?" He asked to a pale blond man. The guy looked scared and replied, "Severus couldn't be here. He wishes to tell you that 3 demigods are at Hogwarts." Severus sold us out, how dare him!

"Which ones, who are their parents?" the bald guy asked.

"My lord, there is Thalia Grace Daughter of Zeus, Nico di Angelo son of Hades, and Percy Jackson son of Poseidon, and apparently savior of Olympus." The blonde told him.

"Hmmm, the son of Hades has a use, the daughter of Zeus would make excellent blackmail material. The savior of Olympus uh, I can take his powers like the son of Hades, I will be ever so powerful. Olympus as well as the wizarding world will have to bow down to me." He said and started laughing insanely. Soon the dream changed.

It was Severus and Dumbledore talking. Severus looked worried, "But how can you expect me to do this, he's my brother!"
Dumbledore looked pained, "We need to keep your cover up as a death eater, if they have to expose themselves, the Malfoys will tell him and you will be in trouble."

"But he's my little brother, and I can't betray them! And, they're super powerful; the dark lord will attack them!" Severus exclaimed.

"Severus, you said it yourself, they can protect themselves." Dumbledore said patiently.

"Okay, but I still don't like it" Severus trailed off uneasily. When I awoke, I knew that the biggest villain of the wizarding world would come for us. I knew, this Voldemort character was no match for Kronos, but still, two megavillians in one year can cause an uneasy feeling in your stomach.

I showered and got dressed, and headed downstairs toward the common room, Percy and Nico were there talking to Harry Potter and the red-headed weasel.

"Hey Thalia," Nico said casually.

"Sup'" I told him. I gave him and Nico a look that said I need to tell you guys something.

"So Thalia, this is Ron, Harry's friend." Percy said. Ron was staring at me. Boys.

"Hi Ron, Harry. Percy, Nico, I had a demigod dream last night." I said the first part in English, the latter was Greek.

"What kind of dream?" Percy asked, also in Greek.

"Voldemort knows we are here. Severus told him."

"How could Sevvie do that?" Nico asked looking hurt.

"Dumbledore forced him, trust me, he didn't want to."

"Whoa! What language was that?" Ron interrupted us looking fascinated. The nerve of him! We were talking about things that could save the world and him sadly, and he interrupts us! He was even looking at me love struck! I just wanted to punch him sooo badly.

"Greek, it's our maternal language." Percy replied patiently, huh, whoever knew he was patient? I saw bushy haired girl coming down.

"I'll tell you about my dream later." I whispered to them in greek.

"Hey, this is also our friend, Hermione." Harry said pointing to bushy haired girl.

"Hi guys, it's time for breakfast. Let's go!" she said. With that, we all headed to the Great Hall. At breakfast, we sacrificed our food again. When we sat down a hundred ghosts floated in. Nico looked mad, and I mean I'm-a-son-of-Hades-and-I-will-drag-you-to-tarturus mad. He stood up slowly. Every kid in the hall was looking at him. Suddenly he lost it, "HOW DARE YOU ESCAPE THE UNDERWORLD AND LIVE HERE! HOW DARE YOU ESCAPE DEATH! HOW DARE YOU ESCAPE MY FATHER! I SHOULD DRAG YOU TO THE FIELDS OF PUNISHMENT, OR EVEN TARTURUS! I WILL-"he was interrupted by Percy who said, "dude, calm down." Nico still looked mad.

"I'm sorry, my king, we are very sorry, we were scared." A quivering ghost approached Nico. Nico started to yell again, "SCARED! I CAN SENSE YOUR AFTERLIFE, NICHOLAS! YOU WOULD BE IN ELYSIUM NOW WITH YOUR ENTIRE FAMILY! WAS IT REALLY WORTH IT TO SPEND YOUR TIME AT THIS SCHOOL INSTEAD OF WITH YOUR FAMILY IN HEAVEN! YOU SHOULD BE ASHAMED! I WILL-"

Percy interrupted again, "dude, chill." Nico had steam literally coming out of his ears.

"We apologize, my king, please don't hurt us." A ghost said timidly.

Nico looked murderous but said, "Okay Bloody Baron, but if anymore ghosts come to Hogwarts after today, I will personally come here and take you to the Fields of Punishment."

"Thank you, my king." a ghost told him. Then, all the ghosts assembled into a line and started to bow. Then a pink toad lady from the staff table stood up and said, "Mr. diAngelo how dare you threaten our ghosts with nonsense?" Nico looked even madder than usual, any minute now, a bunch of blood-thirsty skeletons were going to burst out of the ground. "Professor Umbridge please do not insult our guest, but Mr. diAngelo, I do not wish to see a repeat of today again." Dumbledore stood up and said sternly.

Nico sat down still looking murderous and continued eating breakfast, but every kid in the Great Hall had their eyes still fixed on him.
