Harry read over the letter he had gotten from everyone back at the Capital. It stated that Leone had found one of those dark items somewhere in the castle and they asked if he could ask around to see if some of the students or staff knew anything about what they might be. There was also a p.s. letting him know that the wizards had somehow gotten their hands on a list of people who possessed Imperial Arms. They said that he shouldn't worry too much about it since his name wasn't written down since he wasn't officially a member of the task force, but to still stay on guard since it was known they were his legal guardians so it was likely someone might start asking him questions.

Tucking the letter into his robes Harry made his way to the library where he was to meet with the study group. Maybe one of them would know something.

As he walked into the library Harry saw that Hermione, Neville, the Patil twins, Daphne, and Tracey were already sitting at a table. Neville waved to him when he walked in. "Hi everyone," Harry addressed the assembled group of students. "Anything new?"

"We we're just talking about our substitute the other day," Padma told him. "She seemed so cool."

"You should have seen Ron and Draco's reaction to seeing her," Pabarti said.

"Yeah I'm surprised their jaws didn't dent the floor when they dropped," joked Tracey.

"Well it looks like the two of them are alike after all," Daphne said. "They both have no idea how to handle themselves around women."

"Did you hear what she did to those people who were picking on a first year?" Padma asked.

"I did," Pavarti said. "Lavender said she saw three girls walking with their hair tied together to the hospital wing to have Madam Pomfrey untangle them."

"What I want to know is why we got a sub?" Hermione asked. "I mean I'm not complaining she was pretty laid back, but I don't think any other teacher has called in to fill for someone else."

"Professor Sprout tells me that Hagrid sometimes helps the Care of Magical Creatures Professor out with his lessons," Neville told her. "But apart from that I never heard about anything like that either."

"Professor Esdeath seemed fine in class today," Tracey said. "I mean she had use practice handling swords after all."

Harry knew the reason why Esdeath was not in class yesterday was most likely due to the fact that she was questioning the wizards that were caught sneaking around. If the stories Harry heard about her were true then there was a great possibility that they were dead. He didn't plan on telling that to any of them though, for all he knew the two wizards could have been friends of their families.

Deciding to change the topic Harry asked, "So has anyone done any reading about cursed artifacts?" Hermione was the smartest witch of their age, and the others were purebloods so he figured if anyone would have any idea about what those objects were they might.

"Well from what I know dark artifacts are a pretty broad subject," Hermione told him. "Why do you ask?"

"It's just that I know Professor Esdeath has a interest in them," Harry told her. "And who knows she may start teaching us about them, so it wouldn't hurt to know a little more."

"Well dark objects come in all shapes and sizes," Daphne told him. "Do you know what kind of objects she means?"

"I guess like just ordinary things," Harry told her. "Things like a diary, a locket, a tiara."

Hermione actually perked up a bit at the last one. "Do you mean a diadem?"

"A what?" Harry asked not familiar with the word.

"A diadem it's basically the same thing as a tiara," Hermione clarified. "The most famous one is Ravenclaw's diadem its been lost for hundreds of years though, and from what I know it's not a dark artifact more of a priceless treasure."

Leone found that diadem in a hidden room Harry recalled. Was it possible that one was the same as Ravenclaw's? "What do you know about it?" Harry asked.

"Apart from that nothing much," Hermione admitted. "Although you're far from the first person to ask. Students ask the Grey Lady about it and where it's hidden all the time, although she never gives them a real answer from her."

"She's your house ghost right?" Harry asked. Hermione nodded. "Do you know where I could find her?"

"Well when she's not in the common room she's usually floating around by herself in an empty classroom."

Harry thanked Hermione for telling him, and soon the others showed up to start studying. Tonight he would use the Invisibility Cloak to go and search for the Grey Lady.

An hour and a half. That was how long Harry had been wandering around the castle looking for the Ravenclaw ghost. If it hadn't been for the cloak he would have gotten caught by Filch three times. Harry wasn't sure but it seemed Filch's cat was able to almost see him despite being invisible.

Harry was about ready to give up his search when he saw a transparent figure of a woman glide through a door to a classroom. Taking a chance Harry followed and opened the door.

Floating on the other side of the room looking out the window into the night sky was a figure of a woman with dark hair in a dress. Taking off the cloak Harry spoke up, "Um excuse me." The ghost turned around and seemed a bit startled to see him.

"Yes," the ghost spoke to him. "What do you want?"

"Well I was just wondering if you were the Grey Lady?" Harry asked.

"That is what they call me yes. Why have you sought me out?"

"Well I just wanted to ask you about Ravenclaw's diadem," Harry told her.

"You and every other student," she replied bitterly. "You all wish to find it to further your own glory."

Harry shook his head. "No no I didn't come to ask where it was. Someone found it actually."

The Grey Lady's eyes widened. "How?"

"A teacher found it in a secret room," Harry told her. "But when they found it, it was giving off real negative energy. What I wanted to ask is why it would do that?"

"He defiled it with dark magic," the Grey Lady said in almost a whisper to herself than to Harry.

"Who did?" Harry asked intrigued.

"He made me feel like I was important," the Grey Lady continued to talk to herself. "Made me feel like I could surpass my mother. I told him where I hid it. He was so charming when he was here nearly fifty years ago."

Fifty years ago, Harry thought. Wasn't that around the time that chamber was opened? Harry began to realize who the Grey Lady was referring to. "It was Tom Riddle wasn't it?" Harry asked.

"I'm surprised," she said. "Not many people know him by that name. But yes, it was him."

"But what would he want with the diadem?"

"All I know is that he promised that it would prove me wiser than my mother if I told him where I hid it," the Grey Lady said solemnly. "And then he goes and defiles it dark magic!" Harry was taken aback by her sudden outburst.

"Look," Harry said trying to ease the apparition. "Whatever was wrong with the diadem is gone. There were other things like it that were found, they were purged of whatever it was as well."

"Truly?" the ghost asked and Harry nodded. "So my mother's prized possession has been cleansed of that darkness?"

"Yes," Harry told her. "But the thing that I really wanted to ask about is what was it he did to the diadem? What was that energy?"

The Grey Lady shook her head. "That I do not know. He would talk often about other objects related to the founders as well as his family lineage." That caught Harry's attention.

"So do you think he would try and do this to other things the founders possessed?"

"He was quite obsessed with them so it would be in his character to do so," was her response. "I have lingered for too long I should be going." The Grey Lady floated past him to the door. "I will say thank you. Thank you for informing me that my mother's heirloom has been cleansed of the darkness." With that said the ghost floated through the door, leaving Harry to himself.

So all of those things were somehow tied to Voldemort, Harry thought. But what did he do to them to make them like that?
