Chapter 5: First Monster Attack Of The Year

Harry sat down at the Slytherin table along with Hermione and Neville. Neville was busy working on something that smelled like Demeter. Giving offering to Hades, he told them that his dad said that Snape was just worried about him.

"I don't see why my cousin has to worry about me," Hermione said.

"Dad said that he didn't mean it."

Hermione glared at Harry.

When they were done eating Hermione and Neville went to Care of Magical Creatures and Harry went to Earth Magic. The class sounded like fun and the Professor seem to know what she was doing. Harry drew from the power of the earth and felt a stone pop out of the ground.

"Very good, Mr. Potter," she said.

"Thanks," Harry said, feeling pleased with himself.

Harry thought that the lesson would continue without any problems. He should of known, by now, that would never be the case. Suddenly the ground opened and two things came crawling out from the space. They hissed at him and the few students that were in Harry's year ran for their lives.

"Oh just great," Harry said.

"Die, demigod," one of them hissed, "Revenge for Medusa."

"I didn't even kill Medusa," Harry told them.

"No matter," it said, finally coming through, "All demigods must die!"

Harry twisted his ring and it became a long sword.

"The little hero is armed," said the second.

"I don't care, Stheno," said the first, "He won't be able to defeat us."

"Want to bet," Harry stated.

They lunged at him and Harry shadowed away from them, appearing few feet from where they were. The first one attacked him and he sliced through them, the monster turning to dust.

"YOU KILLED MY SISTER," Stheno snarled, "I'M GOING TO KILL YOU!"

She came at him and Harry was able to defeat it. Harry thanked his father for protecting him and then returned his sword back into a ring.

"Why didn't you get your brother to help," Hermione asked when Harry told them what had happened.

"I wasn't about to draw my brother away from class," Harry told her, "I took care of them, no worries."

"Let's hope that nothing else happens," Neville said.

"Like what?"

"Like more monsters," Neville answered. "I also think that we need to tell Dumbledore what happened."

"I agree," Hermione said, "And find out why the magical protection isn't working."

Everyone nodded in agreement and so they headed for the Headmaster's office.

"I've talked to father and he said that the protection that was placed isn't good enough," Severus told Dumbledore. "I sensed monsters on the grounds!"

"I'm worried about this, Severus," Dumbledore stated. "This is supposed to be a safe place for everyone, but it's not."

"Do you think that Harry should go back to the States?" Severus asked.

"No," Dumbledore answered, "He's needed, as your father knows."

Severus glared at him and said, "I don't like this, Albus."

"I know that you don't, but there's nothing that we can do," Dumbledore told him. "With Sirius Black after Harry's blood, the best place for him is here. I will have a talk with Miss Granger's mother about something that we can use."

"Very well," Severus said and then the door opened and in walked his brother and his friends.

"We already know," Dumbledore told them.

"I thought the magical protection was supposed to work," Miss Granger told him.

"We thought as well, but I need a word with your mother," Dumbledore told her.

"Is this about trying to find some type of protection?'

"Yes, Miss Granger, it is," Dumbledore told her.

"Then I'll call on her," Miss Granger said.

Miss Granger turned around and chanted in Ancient Greek. The air turned cold and then suddenly a figure appeared.

"You wanted to see me, Albus?" Hecate said.

"Yes, my lady," Dumbledore said, "I need to know why the magical protection that we worked on is not working."

"Because it's not approved by the gods," Hecate answered, "I do have something that will be able to help but only Hermione can use it."

"What is it, mother?" Miss Granger asked.

"My chalice," Hecate answered, "I'll let you use it and with it you must use your blood to make the protection. Only this will save the demigods."

"Then I'll do it," Miss Granger said.

"We must make sure that no one finds out," Dumbledore said, "Blood rituals have been banned by the Ministry."

"And why's that?" Miss Granger asked.

"Because it's linked to the dark arts," Dumbledore answered.

"Great, another thing that people can use against me," Miss Granger moaned. "But I'll do it."

"Good," Hecate said, "Now make sure that you drink something to replenish the blood that your going to loose."

"I'll make sure that she does," Severus promised.

"Very well," Hecate said and she made her goblet appear. "You must follow the directions in the book on page 1,268. Once you've used the chalice will return to me."

Miss Granger took out the book and flipped it through to the page. She read it over and then turned to Severus.

"I need to use it throughout the boundaries of the grounds."

"Which will require you to fly, Miss Granger," Dumbledore said.

"I can help her."

"Zeus, will knock you out of the sky," Hecate reminded him. "I was thinking about getting Lou Ellen to come and be with you during the process. She's not with the others on their quest to Greece."

"Then do it," Dumbledore said, "I want this school to be safe for all demigods."

Hecate vanished, leaving her chalice behind.

"You'll be able to do this, Hermione," Potter said.

"I know," Miss Granger said, "But that doesn't mean that I'm not worried."

"I know!"

Severus cleared his throat and said, "We still need to talk about something on Saturday."

"If this is about-."

"Not here!" Severus snapped.

"Fine!" Miss Granger snapped and she stormed out of the office.

"Why do you have to be like that?" Dumbledore asked.

"Blame my father," Severus said.
