Just as the two were about to descend the stairs, Kreacher popped in and bowed.
"Master, Kreacher is being having a Dark object you is needing to see right away," the old house elf said as he held out a large necklace.
It was a locket, a man's locket. There was a huge diamond S on the black rectangular front. Its silver chain glimmered in the light of the hall. It was a nice-looking locket, however, the whole thing radiated evil. Like a dark wavy cloud was surrounding it. It couldn't be seen, but it could be felt.
"Where did you get this, Kreacher?" Sirius asked, pulling Harry back a bit.
"Master Regulus is being given it to Kreacher. Master Regulus tasked Kreacher to destroy it, but Kreacher cannot." The elf hung his head; this was his greatest failure.
"Reggie ordered you to destroy this. Why?" Sirius asked, taking the locket but holding it at arm's length. The feeling of Dark magic crawled up his arm, making him want to fling the thing away.
"The Dark Lord used Kreacher to hide the locket. Kreacher almost died. Master Regulus had ordered Kreacher home. When I obeyed, Master nursed Kreacher back to health. Then he ordered Kreacher to take him to the bad cave. Master Regulus was being very angry at what he found. He drank the vile potion and ordered Kreacher to take the locket and destroy it. Kreacher cannot. I have being trying," the old elf explained with tears dripping from his large eyes.
"What is this thing?" the dogman asked, still scrutinizing the necklace from afar.
"It is being a Horcrux," the elf answered, still crying.
"Shite," Sirius said, dropping it immediately. His eyes were wide with fear and disgust showed on his face. He backed away until his back hit the wall, his arm still held out in front of him, like he was wishing it was removed, after touching such a vile thing.
Harry, now that he wasn't being held back, knelt and put his hand on the distraught elf's shoulder. "I'm sure you tried your best, Kreacher. Sirius will help you now. Won't you, Sirius?" he asked, looking up at his godfather.
"Yeah," the older man sighed as he dropped his arm to his side, after shaking the feeling of evil off it. "I know a bit about these evil things. I'm sure I can figure out how to destroy it, but I might need to use it first. Some rituals will tell if it's the only one. There was a Dark Lady, somewhere in Romania, about a hundred years back or so, who made three. They almost didn't find out in time. So, I'll take a look and make sure we're not getting rid of the only thing that can help stop the Dork Lord."
"How do you know it's Voldemort's?" Harry asked, keeping his eye on the necklace.
"Kreacher said he had been doing something for the Dork Lord when Reggie found it," the older man explained, shrugging his shoulder.
"Oh, yeah, sorry, I was paying more attention to your horrified look. That thing feels nasty," Harry said, then chuckled at the derogatory names, and he turned back to Kreacher. "See, we'll help."
The elf's tears dried up and he slowly nodded his head in thanks. Then he glanced at his master, who waved him off, and then the elf popped away.
"So, this thing is evil, huh? Figures since it's Voldemort's," Harry said, leaning to get a closer look, still knelt, only to wrinkle his nose at the feel of the thing.
"Yeah, don't get too close," the dogman said, pulling on Harry's shirt. Didn't this boy have an ounce of self-preservation?
"I won't," the boy said, shaking off Sirius' hand, and leaning a bit further forward to get a good look without touching. Weird though, when he got closer his scar hurt, not much just a twinge. "Sirius, my scar kinda hurts near that thing," he informed the man as he quickly scrambled to his feet and backed away.
"Shite," was the only reply as Sirius snatched up the necklace and hurried down the stairs, into a study on the ground floor. If what Harry said was true, then that didn't bode well for what was in the boy's scar. It was something he was going to have to research right away. The last thing he wanted was for his godson to have any connection to that vile man. He surely hoped it was just a connection, and not what he was thinking.
Harry hurried after him, worried about what caused the man to panic. "What? What's wrong?" he asked when he reached the study. He watched Sirius frantically look around, and then the man's face was overcome with relief as he spotted a metal-looking box.
"I need to get this thing put away. This iron box will help keep the taint from escaping," Sirius said, closing the box tightly and locking it immediately. He didn't have the key but that was okay. He'd just burn the whole damn thing with Fiendfyre. It was one of the only ways he knew to destroy them. Still, he'd hold off until after that ritual. Although, he still had a sneaking suspicion that Harry might be connected. He had no idea if it would, but it might hurt Harry if he just went off and destroyed the thing. He was going to have to do a ton of research and magic to fix this if that were true.
That and, he'd have to tell the Order. He wasn't going to be like Dumbledore and keep everything secret. He was sure the old man knew about these evil things, and no one knew. He would keep some things to himself, it wasn't anyone's business what he did with Harry. However, who knew who could help with this? Maybe Mad-Eye, or Remus, or even Bill? They'd had to have come across these things before, or at least knew about them. Hell, he'd even ask Snape, if it would help Harry.
