Chapter 1

A/N: This is my first fan fiction. Please read and review. It would mean so much to me. Also Luna and Snape are Demigods in the story. A special thanks to my Beta, Bright Eyes Illusionist.

Disclaimer: I do not own Percy Jackson and Harry Potter.

Snape POV

Harry Potter was making a Potion with his fellow teammate and best friend Ronald Weasley. They had realised that they had missed a crucial ingredient for the potion. Of course that's when Professor Snape came over to look at their potions.

"Your potion is incorrect, what ingredient did you miss this time?" Asked Professor Snape

"I don't know sir," mumbled Ronald Weasley

"Ten points off Gryffindor"

Severus Snape sighed. Potter wasn't going anywhere in his classes. Potions was an important skill to learn in life. He was the only one who had a chance of defeating You Know Who known as Voldemort. Snape deeply cared about the boy not that he showed it. He was glad Harry had that Granger girl to help him. His father, Lord Hades, hated Voldemort because of all the trouble he was causing in the underworld.

"Your next potion will require extreme skill and precaution. All of the sixth years will be doing this it with you. The potion will not be in your book rather it's my own invention so the instructions will be on the board. The person who does the potion correctly will receive fifty house points. My acquaintance, Alley will be judging," Said Professor Snape

With a wave of his wand Severus enlarged the classrooms. The sixth year Ravenclaws and Hufflepuffs filled the tables.

"You may begin"

Harry, Ron and Hermione gathered the ingredients and started working on the didn't say what colour it should be but the trio got it looking yellow-orange. Hermione checked to make sure they completed it right.

"I will be back, class no talking or messing about. The potion can kill you," said Professor Snape

Harry POV

Ron was suddenly jumping up and down.

"Harry I dare you to follow Snape," said Ron

"I'll do it only because this is the first time he left the class" said Harry

"Don't do it you'll get into to trouble" said Hermione

"Chillax mionie, he can use the invisibility cloak and he's in his office now"

"Okay I'm doing it"

Harry grabbed his invisibility cloak from his bag, slipped it on and crept into Snape's office. Snape was having a conversation with someone.

He seemed to be saying;

"Lady Athena I'm glad you could make it", uttered Snape

"It was no big deal when it comes to education and I can check on my two daughters who attend this school", Said Athena

"There are two demigods at the school, I didn't notice"

"You will go by the name Alley and remember they're making Nectar"

What's a Demigod and what is Nectar? Harry wondered. He moved out of his hiding spot to get a better look at the person whom Snape was talking too. She was a stormy grey eyed woman wearing a blue knee length dress. Out of nowhere, Professor Snape looked at him in the eye.

"Potter I know your there so get out before I expel you," said an angry looking Snape

Harry came out of his hiding spot, his face red with embarrassment.

"I will give you a quick potion that will make you forget this conversation" He said handing him a potion. Harry left to meet his friends.

"So what did you find out" asked Ron

"All I remember is Snape handing me a potion and telling me I had to drink it," said Harry

"So he caught you and gave you a memory potion, you were lucky he didn't do worse," said Hermione

Professor Snape's friend Alley cam to judge the potions.

"I am Alley, a friend of Snape's and I am here to see who has done the potion correctly. As it is a difficult potion, I don't expect many of you to complete the potion."

Alley was a stormy grey eyed women. She looked cheerful but fierce. She moved around table to table judging each potion. Once she reached Malfoys potion she stayed there for some time. She moved around the classroom swiftly. She finally reached Harry's table and examined the potion. Then she looked at Harry.

"You remind me of someone I know" she said and walked to the front of the room.

"I have made my decision .Unfortunately no one has made the potion correctly, however I would like Snape to award some points to Hermione Granger, Ron Weasley and Harry Potter as well as Draco Malfoy ,Vincent Crabbe and Gregory Goyle"

"Ten points to Gryffyndor and Slytherin, Class Dismissed," Severus Grumbled

The students ran out of the classroom eagerly. The trio headed back to their common room.

Luna POV

"We are creating the same potion that the sixth years created today earlier, my acquaintance Ally will be judging the potions," said professor Snape "This potion will require extreme skill and precaution. It is very deadly to humans. The instructions will be on the board as it is my own potion"

Professor Snape casted a quick spell on the board and slowly the instructions wrote itself. Luna worked on the potion by herself. Everyone else had a partner or was working in group of threes. Luna concentrated on getting the potion right. When Luna was done, she notice that it was the exact same colour as Nectar which was very weird.

"Your time is up, Alley will be judging "said Professor Snape

Luna looked at Alley and realised it was her mother Athena. That meant professor Snape was a demigod! But who would be his godly parent. Athena went over table to table judging and examining each potion. When she came to Luna's table she smiled at her. Athena finished judging the potions.

"I have made up my decision the only person out of all of fifth and sixth year students who completed the potion Corrected is Luna Ni I meant Lovegood. I have a small gift for her. She will collected it after class"

"Congratulations to Luna for the first person to complete it correctly and fifty points to Ravenclaw, Luna stay behind," said Snape

"Professor Snape is a Demigod He is a son of Hades or as we gods call him the secret son of hades," said Athena

"Call me Snape, I was a Demigod wizard so I was exempt from the prophecy and No one but the gods know that I'm a Demigod," said Severus

"What about the Demigod wizard spell, I'll still have Dyslexia when I get in contact with a demigod," said Luna

"I'll do a spell that removes your dyslexia when you're in the wizarding world"

Snape casted the spell and everything was much better.

"Snape I want you to swear on the River Styx that you will protect Luna from any harm to the best of your abilities" said Athena

"I swear on the River Styx"

Athena handed Luna a small package, inside was a small bracelet full of little charms.

"It will allow your demigod abilities to show through because I have a feeling you will need it soon"

Athena left with a flash.

"You'd better head back to your classes now"

"I should and I'd just let you know that I don't believe in nargles and that sort of stuff it was my wizarding world disguise," said Luna

"That's impossible Luna not believing in Nargles and that sort of stuff, it's like Malfoy being nice to Potter", Snape muttered to himself though Luna heard him.
