Chapter 9: Halloween Attack

Halloween rolled around and Petunia could tell that this was one event that Lily had been looking forward to. The Full Moon and come and gone and Petunia had spent it with Remus, helping him recover quicker. There was another round of attacks on muggles and muggleborns and the Ministry was doing everything they could to prevent the muggles from noticing. Petunia knew that her fellow Slytherin's were cheering their deaths, which was enough to make her sick.

Everyone had just entered the Great Hall when someone came running in. Petunia didn't know who he was but Dumbledore seem to know.

"Hogsmead is under attack," he said.

"What!" Dumbledore said.

"Oh I hope they get some mudbloods," Bellatrix begged.

"Sick!" Petunia hissed.

"Everyone head back to your dorms," Dumbledore ordered and then Petunia saw him nodding.

"Narcissa, take them back to their dorms," Petunia said, "I'm going to have some Halloween fun."

"What are you talking about?"

"I'll tell you in time," Petunia assured her and she hurried off with the Headmaster.

When both she and Dumbledore arrived five Aurors were already dead and there were all sorts of dark creatures and followers of Tom Riddle running around. Petunia grinned and said, "Looks like the fun's started without us."

"Don't hurt anyone that isn't wearing the dark mark," he ordered.

"Don't worry, I only take care of garbage," Petunia said to him.

She closed her eyes and the one gift that her mother had given her, one gift that she hoped that Lily never saw, broke through. Wings sprouted out of her back, fangs grew out of her mouth, her nails turned to claws, and she allowed her blood lust to grow. She had changed into guard to Hecate, a winged vampire.

"Time to feast," Petunia snarled and she lifted off the ground, leaving Dumbledore to handle things.

"What the hell is that?" one of the Aurors asked.

"Something that I hope you never have to face," he said, "Get those Death Eaters, now, and save those in the village."

"Yes, sir," he said and they hurried off.

"Happy hunting, Petunia," Dumbledore said and he went to help out.

Petunia crashed through a window and landed a few inches from a follower that was about to rape a girl. She let out a scream and rammed her fist through his back, breaking his spine, and pulling out his heart. She tore into it, the taste of blood filling her mouth. The girl screamed and Petunia backed off, allowing those to escape. Soon the village was filled with the screams of dead followers, all of them lying in heaps, their hearts ripped out of they're bodies.

Petunia saw silver animals coming forth and the creatures that were affected gliding away. She landed and forced the shell to form around her body. Soon a twelve-year-old girl stood there.

"Now that was fun," she said, grinning.

"Glad that you enjoyed yourself," Dumbledore told her. "Well looks like their all dead."

"Good, now I'm heading to bed," she said to him.

"Don't you want to know what those creatures were," Dumbledore asked her.

"Servant of Hades," Petunia answered. "How they're here, I don't know."

"I think that Lord Hades should be told," Dumbledore advised.

She looked at him and said, "Don't worry, brother, he will be told."

"Good!" Dumbledore said and Petunia headed back to the school.

The next morning the talk was about the failed attack on Hogsmead. Even though Tom's supporters had managed to try and kill people it was the supporters that ended up dead. Petunia grinned at the image of the man screaming as his heart was ripped out of his chest. She then sighed. Sometimes you had to become a monster to defeat monsters. She hoped that none of her friends ever saw her like that.

"What do you think about this game that we're going to on Saturday?" Lily asked her.

"Quidditch, pointless," Petunia answered, "Though I'm happy that Potter and his dumb friends can't enjoy it."

"Did you ever see a match?"

"Yes, hated it," Petunia answered.

"What about what happened yesterday?"

Petunia mentally chuckled and said, "I heard that there were problems."

"Well someone told me that Dumbledore has something that he uses," Lily told her. "Though I don't know if I believe that."

"The Headmaster is a powerful wizard, Lily, he most likely has many things," she told him. "Let's pray that we never meet whatever he's using."

She nodded and Petunia hoped that she would drop the subject.

Of course the others in Slytherin didn't drop the subject so easily. They were all mad that the supporters, now known as Death Eaters, hadn't killed people like they had hoped. Bellatrix was the one that was furious.

"What the hell is that old goat using?" she asked her fellow Slytherin's. "I mean, rumors are going around that it's some kind of monster."

"Ate the Death Eater's hearts out."

"My father was one of them," Bellatrix said to them. "When I find the thing I'm going to make it wish that it had stayed in hell."

"I agree," said another.

"What I want to know is if this creature is dark; and killing Death Eaters, then why is that fool using it?"

"Because he wants to win," Severus answered.

"Who asked you, half-blood," Umbridge snarled.

"Be nice, toad," Petunia said to her, "He was just answering a question."

"Which wasn't directed at him."

"Cry me a river and build me a boat," Petunia said. "Of course if you want to be so Slytherin why don't you go out there and find it."

"Only a fool would do that."

"Luckily, we have plenty of them here," Petunia said to them, "Though if you seek something it does have a habit of arriving."

"Did we ask for your opinion?" Lucius asked her.

"I don't have to wait for you to ask," Petunia told him. "The fact that you're having a public discussion means that it's open to anyone to answer. Why don't you make it private if you don't want your questions answered?"

"Come along," he said and the group left.

Petunia grinned.

A/N: Petunia is showing that she's not someone that you mess with and she can really mess up your day.
