It was the day of the Wedding. Bill and Fluer's wedding. Harry still couldn't her but look back on the day he fought the Death Eaters at the Ministry in fifth year.
Flashback:
"Let me go after him, Remus!" Harry shouted. Remus finally let Harry go, and Harry reached the Veil in time to grab Sirius's hands without fully going into the Veil, so he didn't die. He pulled Sirius from the Veil and hugged him like his life depended on it.
"Harry. I'm so sorry, I should've stayed behind I'm so so sorry." Sirius said.
"It's okay. Let's finish this." Harry answered. And they did. The Ministry gave him a trial, and Sirius's conviction was overturned, and Sirius was given custody of Harry.
End of flashback.
Harry smiled, remembering the last part.
"Harry?" A voice behind Harry called.
Harry turned around and raised his wand.
"Animagus form?" Harry asked. Sirius whispered under his breath that he was tired, but did it nonetheless. Harry lowered his wand.
"Sorry, had to check." Harry said.
"It's alright." Sirius said with a chuckle.
"It's my birthday." Harry said.
"Happy Birthday. And the Trace is off of you. You can't be tracked anymore." Sirius said with a smile.
"We both know there are other ways to track people." Harry said.
"True. What's the mission Dumbledore gave you?" Sirius asked.
"Not here." Harry said.
"You'll let me join you, right?" Sirius asked.
"Yeah. Just.. Be careful. This mission is essential to defeating You-Know-Who. You can't be reckless. You've got to be careful. I know our plans won't always work, trust me I know that, but we still need to be careful." Harry replied.
"I'll be careful." Sirius said.
"It might take a long time, but your knowledge of Dark Magic given your family will help us. I'd bring Remus, but he has other missions. You don't." Harry said.
"Right." Sirius said.
"After the Wedding. And.. We can't say You-Know-Who's name. He Tabooed it. Anyone who says it can be tracked." Harry said.
"Alright." Sirius said.
"For now, let's enjoy the wedding and hope no Death Eaters show up looking for me." Harry said.
"You're good at Defense Against the Dark Arts. We should be good." Sirius said.
"First place e go after the Wedding is Grimmauld Place. I know you don't like it there, but we have to go there. Kreature probably kept the Locket you threw out. We need it. Part of the mission, I'll explain later." Harry said.
"Alright. We need the Locket. Any idea why we can't open it?" Sirius asked.
"Yeah, I do. You-Know-Who speaks Parseltounge. I bet he made it so you can only open it with Parseltounge. I'm the only other person who can open it that I know of." Harry said.
"Alright. Must be some strong Dark Magic." Sirius said.
"Very Strong. Can you control Fiendyre?" Harry asked.
"I can." Sirius said.
"Good. Better get some Basilisk Venom to be safe. Killing Curse should work for Nagini.. Gotta find the others though. Seven, destroyed one, looking for another I've got a feeling it's at Grimmauld Place.." Harry said to himself.
"What are we looking for?" Sirius asked.
"You're not going to wait, are you? Alright, my room. Let's head up." Harry said. Sirius complied. Harry placed Silencing Charms on the walls.
"Ever heard of a Horcrux?" Harry asked.
"Yeah, Dark Stuff. Why?" Sirius asked.
"Because, You-Know-Who made several. Seven, if I'm right. The Diary I destroyed in the Chamber of Secrets was one. That's the mission Dumbledore gave me. To find, and destroy, the Horcruxes You-Know-Who made. Locket is one, but we have to open it to destroy it. And, it'll probably try to fight us." Harry said.
"This is dangerous, Harry." Sirius said.
"I know. I've got to do this, though. Oh, and Dumbledore destroyed another. That gives us five to find. I reckon he probably used items that belonged to the founders. That's where we'll start. Nagini, his snake, I'm pretty sure she's a Horcrux too." Harry said.
"What about the Cup of Helga Hufflepuff?" Sirius asked.
"Bellatrix is in Azkaban, right?" Harry asked.
"Yeah." Sirius answered.
"Does that give you access to her Vault, given the her husband is in Azkaban too?" Harry asked.
"Yeah, it does. You thinking there's a Horcrux in there?" Sirius asked.
"Bet there is. And I bet it's the Cup. Any idea what he could have used for Ravenclaw?" Harry asked.
"Diadem. The Lost Diadem of Rowena Ravenclaw." Sirius said.
"Might be at Hogwarts, maybe in the Room of Requirement. But You-Know-Who took control of the school when Snape became headmaster. So how we'll get in, I have no clue. It's possible he knows about the secret passages by now, so I doubt we'll be able to get in through Honeydukes. We could apparate to the gates. Or at least, you could. You'd be able to slip in as your dog form without setting off the Wards. But you can't let Snape see you, as he knows you're an Animagus. You might want to take my cloak too, just in case." Harry said.
"Yeah. Does Remus know?" Sirius asked.
"No, he doesn't. I know you guys are dating and all, but you can't tell him. He'll want to come too." Harry said.
"So let him come." Sirius said.
"We'll talk to him first. Can you go get him?" Harry asked.
"Yeah. I'll he right back, just stay here." Sirius said, and left to find Remus. Remus was already downstairs.
"Hey, Moony. Harry wants to talk to you. He just talked to me, but he wants to tell you as well. It's about the mission Dumbledore gave him." Sirius said.
"Sure, Pads." Remus said, and followed Sirius upstairs to Harry's room. They knocked gently.
"Come in." Harry said. Remus entered the room and sat down on the bed. Sirius followed. Harry had been reading a Dark Magic book. Very dark.
"May I ask why you're reading that?" Remus asked.
"Looking up Horcruxes. How to destroy them. Very few methods." Harry said, closing his book. He set the book down on his nightstand and sat up.
"Still wondering what the mission is? I'll tell you, but you can't tell anyone. Sirius already knows and convinced me to let you come along even though you have other missions." Harry said.
"Alright." Remus said, he was very confused and it seemed to chow on his face.
"Confused? That's alright. You-Know-Who made horcruxes. If I'm right, he made seven. Two have already been destroyed. So we have five to find. Sirius and I have been talking about what they might be and where to find them." Harry said.
"How do we know what they are?" Remus asked.
"Well, we think we already know where one is. Remember the Locket we found but couldn't open? I'm thinking that was a Horcrux. Good thing Kreature was stealing a lot of the stuff we threw out. Otherwise the Horcrux would be long gone. But that also means we have to go back to Grimmauld Place. We're also thinking that the Cup of Helga Hufflepuff and the Diadem of Rowena Ravenclaw are Horcruxes too. And You-Know-Who's snake, Nagini. I think she's one too. That should make him mortal. Seven Horcruxes, seven pieces of his soul. But one has to stay in his body, meaning after six are destroyed he's mortal." Harry said.
"Where are they?" Remus asked.
"The Cup is in Bellatrix's Vault, we're thinking the Diadem is at Hogwarts, in the Room of Requirement. I just thought of something. Dobby works at Hogwarts. He can get it for us, and could probably get some Basilisk Fangs from the Chamber of Secrets. And maybe even the Sword of Gryffindor from Dumbledore's office." Harry said.
"How would the Sword help us?" Sirius and Remus asked in unison.
"It's Goblin-Made. Dirt and Rust don't affect the Blade. The Blade was designed so it only takes in that which makes it stronger. In my second year, I used the Sword to kill the Basilisk. The Blade absorbed the Basilisk Venom because it would make the Blade stronger. Therefore, the Sword is impregnated with Basilisk Venom. Hence why Dumbledore left it for me. He knew it could destroy Horcruxes." Harry said.
"Okay, so the Sword is useful. We've planned at least a little." Sirius said.
"And hopefully, Mrs. Weasley will stop preventing me, Hermione and Ron from talking and making plans now that you both are coming with. Not that she can stop us anyway, given that we're seventeen. I'm free to leave any time. But I've got to stay for the wedding." Harry said.
"Alright. We should all get ready, see you in a bit." Remus said. He and Sirius left, and Harry put on a set of Dress Robes. He then went downstairs.
"You look good." A voice behind Harry said. Remus's voice.
"Your nickname?" Harry asked.
"Moony. Sirius used to call me Rem too, and I used to call him Siri. We all used to call you Pronglet." Remus said.
"Alright. Sorry, I had to check." Harry said.
"It's alright. You really do look great, though.
"Thanks. We should take our seats." Harry said. They took their seats. But the Wedding was cut short by Death Eaters, and a message from Kingsley. The Minister was dead. Voldemort was taking over the Ministry. Remus, Sirius, Harry, Ron and Hermione apparated to Grimmauld Place. They were safe, for now.
