The next few weeks went by fast. Harry asked Sirius regularly how the key hunt was going. The house elves all died out so Sirius was left searching a huge house by himself. Harry offered to help, but Sirius turned him down. He explained that it took months to make his house livable for Harry, and this house is in terrible condition after being neglected for so long. There was also a nice amount of dark artifacts that Sirius didn't want Harry to see.

One evening in April, Harry ran into Lupin's office and hugged him.
"Hi, Harry," Remus said cheerfully.

"You were supposed to have your baby today," Harry said. "A boy named Teddy Remus Lupin. You ask me to be his godfather; however, considering that Sirius didn't die yet, you may want to ask him instead. Meanwhile, you're not even married yet."

"Are we going through this again?" Remus asked with a smile. "What happens if Teddy is a year younger than he was supposed to be?"

"I guess it doesn't really matter," Harry said. "I changed the future so much; I have no right to complain about you making minor changes. I just feel guilty that I delayed your happiness for a year."

"I chose to delay it," Remus said, "but you gave me extra years of happiness. You have nothing to feel guilty about."

Harry hugged Remus again and left his room.

On the evening of April 30th, Sirius called Harry through the mirror.

"I found it!" he said. "I finally found the key. I'll get the object tomorrow to destroy it."

"That's great!" Harry said. "You won't even have to use polyjuice potion, do any unforgivable curses, or ride out on a dragon. You just walk in with the key and take what you need."

"Remind me in the summer that I want to hear your dragon story," Sirius said. "I'm sure it's exciting."

The next evening, Sirius walked into the great hall towards the end of dinner and flashed Harry a thumbs up. Harry ran over to him.

"It was destroyed," Sirius said grinning widely. "Kreacher did fiendfyre again."

"Did you have a hard time getting it?" Harry asked.

"Not really," Sirius said. "Let's wait for Albus and go up to his office."

Professor Dumbledore walked over to them.

"Was your mission successful?" he asked.

"It was," Sirius answered.

They went upstairs to Dumbledore's office.

"The hardest part was finding the key," Sirius confessed. "It took so long to find it. Once I had it, I went to Gringotts and said I wanted to get something from a vault. When the goblins saw I had my key, they didn't ask any questions. There were lots of things in the vault. It was crammed from ceiling to floor with golden coins and goblets, silver armor, the skins of strange creatures, potions in jeweled flasks, and a skull wearing a crown. There were jumbles of chains. There was a jeweled goblet that I thought might be it, but then I remembered that it's small and gold, has a badger engraved on it and has two handles. There were lots of galleons there. There were shields and goblin made helmets. I finally saw the cup all the way on the top of the vault. I couldn't reach it. I tried climbing on suits of armor. Eventually, I managed to get it."

"At least you didn't have to escape on a dragon," Harry said with a smile.

"I want to hear how you did it," Sirius said.

"Ron, Hermione and I planned with Griphook," Harry said. "Hermione used polyjuice potion to turn into Bellatrix. She transfigured Ron so that he would look different. I used my cloak, and Griphook stayed on my shoulders. We apparated to the Leaky Cauldron. As soon as we entered Diagon Alley, a bunch of muggleborns noticed us. One of them ran after Hermione, asking what happened to his children. He tried to kill her, and Ron had to stun him. Travers met us and we couldn't get rid of him. They used probity probes to check each person who came in. I confounded the guards so that they won't check us. I had to do the imperius curse on a goblin and Travers in order to get to the vault. We crashed into a waterfall and the cart smashed. Hermione turned back into herself and Ron lost his disguise. We tried to search the vault, but anything we touched, burned and multiplied. The vault was exactly as Sirius said, except that there were burning hot copies of everything we accidently touched. Eventually, Hermione did levicorpus on me to get me to the cup. We had to stun lots of goblins to escape. We released the dragon and flew it to safety. It took a long time until the dragon finally flew low enough to let us go. Tom was furious when he found out. He went to check all his horcruxes which was how I found out that there was a horcrux in Hogwarts. We apparated to Hogsmeade. As soon as we got there, we heard a horrible scream and were surrounded by death eaters. They tried summoning my cloak, but it didn't work. They sent dementors after us so I had no choice but to do a patronus. Aberforth quickly opened a door and whispered for me to come inside. He told the death eaters that he set off the caterwauling charm. He said it was his patronus that they saw. He gave us some food and talked to us for a while. He saved my life twice. He also said some not nice things about you. He told us about Ariana. He then asked Ariana's portrait to do what she needs to. He had a secret passage that went from Ariana's portrait to the room of requirement. All the students I recruited for Dumbledore's army in my fifth year who stayed in school hid in the room of requirement since Hogwarts was taken over by death eaters. Ariana brought Neville to meet us. One of his eyes was swollen yellow and purple. He had gouge marks on his face. He said that one of gashes on his cheek was from refusing to do the cruciatus curse on fellow students during dark arts class. He told us that Luna was kidnapped, but we knew that already since she escaped Malfoy manor with us. He also said that Michael was tortured for releasing a first year they tied up. They tried kidnapping Neville's grandmother in order to get him to stop Dumbledore's army. I was in charge in my fifth year, but since I didn't come back for my seventh year, Neville took over. He took us to the room of requirement which was full of runaway students. Seamus's face was bruised and puffy. Meanwhile, as soon as Neville heard we were back, he contacted the entire Dumbledore's army to come fight. Luna and Dean came back followed by Ginny, Fred, George, Lee, and Cho. I explained that I needed to find something that belonged to Ravenclaw. Luna suggested the diadem and took me to the Ravenclaw tower to see it on her statue. Alecto Carrow was waiting for us there. She touched her dark mark in order to call Voldermort. Meanwhile, Luna stunned her. Amycus tried to get in but couldn't answer the question. He asked McGonagall for help and they both came in. Amycus said he would tell Voldermort that the kids pushed the dark mark since he couldn't see me through my cloak. When McGonagall said that he can't, he spit on her. I quickly came out from under the cloak and did the cruciatus curse. McGonagall did the imperius curse on Amycus so that he will give up his and his sister's wands and let McGonagall tie them up. Snape came and he and McGonagall dueled."

"Are we starting the Battle of Hogwarts?" Dumbledore asked.

Harry nodded.

"If that's the case, we need Remus and Severus here," Dumbledore said.

He sent messages to both of them to come immediately.
