Disclaimer: What part of fanfiction do you people not understand? If I owned Harry Potter would I be writing a fanfiction?

"Now who did you bring with you?"

Fawkes flew into the room and sat down on his perch. Harry took this as cue to walk into the room himself. "Oh, Harry. Fawkes went to take you away from the muggles?" Dumbledore asked, "Were they treating you that horribly?" Harry managed a small shake of the head.

"T-they were treating me just fine Professor," he choked out.

"Then I wonder why Fawkes wanted to take you away?" Dumbledore said curiously.

"Hello Dumbledore," Sirius said in answer. Dumbledore's attention deterred from Harry and focused on the pitcher. Harry looked to Dumbledore's face and saw, for the first time, a look of pure surprise.

After a minute seemed to have worked out what had happened. "Good show Fawkes," he praised the bird. "You see Harry," he said motioning for the young wizard to take a seat, "not even I had thought this possibly. Today, Fawkes has proved me wrong. Though, Harry, I must warn you. If we do not figure out how to return Sirius to his material form by sunset tomorrow then he will be lost, I fear, forever."

Sirius and Harry took in their new information. "You mean you don't know how?" Harry sputtered. Dumbledore gravely shook his head. "How long do we have then?" he asked.

"Twenty-nine hours," replied Dumbledore. Then Dumbledore walked to the door.

"Where are you going?" asked Harry.

"To look for answers. Search the books in my office while I am gone," Dumbledore said while closing the door. Once the door closed Harry heard a distinct pop signalling that Dumbledore had disapparate. Why didn't Dumbledore just disapparate in his office? 'Maybe it leaves a signature like a wand and he didn't want anyone to come to his office with me in it,' he thought. Yes that would be it.

Harry set Sirius down on Dumbledore's deck and walked over to a wall filled with books. Harry scanned over the titles : Gringrotts Goblins: What They're Really Like, Wizarding Chess VS. Muggle Chess: Which one is king?, All About Pensives, So You Want To Be A Headmaster..., Apparating Anatomy, 7000 Things For Ghosts To Do, The Book Of Replenishing Pranks: Do one and another will appear, So Your Friend Died And Was Brought Back By Phoenix Tears and You Want To Know How To Keep Them From Getting Lost Again.

Harry pulled out the last book and stared at it oddly. He ended up coming to the conclusion that some people just have too much time on their hands. Harry sat down next to Sirius and showed him the text. "Lucky for us some people have too much time on their hands," he said as if reading Harry's mind. Harry nodded and cracked open the book.
"Where's Hermione when you need her," he muttered as he began to read.

Phoenix tears are very powerful and they have probably saver your friend's life. There are two ways of bringing the person back to their original form. Therefore other then the introduction this book contains two chapters. Flip to chapter one for what to do when you no longer have you phoenix around. Go to chapter two if you still have the phoenix.

Harry flipped to two.

Lucky you! You have a very easy time her indeed. Since you still have the phoenix about all you have to do is get the phoenix to create a fire. Then pour the tears over the fire. The person who died shall be back without a glitch (1).

(1)The person sometimes receives minor burns.

"That's all!" Harry mumbled shutting the book. He got up and walked
over to Fawkes. "Fawkes, can you make a fire? Please?" he begged. Happy to oblige the phoenix set the book on fire. "Err, I hope this doesn't happen again." Harry said with a nervous laugh.

He then went and picked up Sirius and before Sirius could complain he dumped him over the fire. The fire sizzled and crackled. It turned blue, green, and then back to red. Then it started to die out. In its place sat a very skeletal looking Sirius. "What in the" Sirius began but a popping sound interrupted him. Dumbledore was back.

"I see you found out how to revive Sirius Harry," he said calmly.

"Yeah, um, sorry about your book sir." Harry replied.

"I daresay I have to many of them anyways," said Dumbledore, "now, Sirius, you need to eat something." Not a truer fact could he have uttered. Sirius' eyes were sunken, he could have slid between the bricks for he was so thin, and his skin looked like it was falling off his bones. Sirius nodded and food appeared in front of him.

After a while when Sirius insisted he was full the matter of what to do with Sirius arose. "Now as you both might have realized the entire world cannot know of Sirius' condition. It would not only endanger him, but phoenixes as well. Do you understand," Dumbledore asked. Both Harry and Sirius had already come to this conclusion and they nodded their agreement.

"Good. Though I do not think you have quite realized how secretive this must be. Yes, Harry you may tell Miss. Granger and Mr. Weasley but that is all. I shall tell Professor Mcgonagall. No one else is to know. Not even the Order. Do you both understand," Dumbledore explained. Again the pair nodded in agreement.

Dumbledore started talking again, "I am not, however, suggesting Sirius go into hiding again. As you know Harry, Professor Umbridge has been fired. Consequently the position of Defence Against The Dark Arts is once again open."

"You aren't suggesting" began Sirius but he was cut off a second time.

"Yes, I am suggesting that you, Sirius, fill in the position." Dumbledore finished.

"But what about the secrecy?" Harry questioned.

"Sirius' appearance shall be changed and he will be given an alias. No one will make the connection Sirius Black and Lirus C.K. Isab," as Dumbledore said this he created Sirius' name in red sparks and rearranged the letters to form the alias. Sirius nodded his approval and Harry sat and watched in silence.

"Are you ready?" asked Dumbledore.

"Yes," Sirius answered.

"Apparo," yelled Dumbledore as he cast the spell.

The change was instant. Where Sirius was standing a slightly shorter man. He had brown hair that resembled Sirius' own. He had ice blue eyes and was of normal weight. When Sirius spoke his voice was similar, "Wow," he said.

"Now, Lirus, you may not take off this cover until the end of the year," explained Dumbledore, "Then you may change to your normal self for the summer and change back when the next school year comes. You do not have to stay when Harry leaves the school but you may if you want."

Lirus said, "Thank you Dumble- err- Professor."

"Now off to the DADA teachers office and room for you two. I have had a cot brought in for you Harry. I bid you both a goodnight." Dumbledore said in dismissal.

Harry and Lirus rose and walked off to the DADA office.

A/N: A Thankyou to Eric2(I hope this answers your question), volleypickle16 , and MalusMagus(I know Remus wouldn't acutally take the DADA job back as you probably figured otu from reading this chapter and I mean the last major time her saw Remus) for reviweing. Keep it up guys and so will I!
