Prologue
The air was thick with terror and mist. A raven-haired girl lay flat on the ground in that deserted alley. Her eyes tight shut and gasp of pain escaping from her thin lips. Even with her eyes closed, she could sense those hideous creatures drawing near. What did they want from her? What on earth were these things?

Just few miles away, from the corner of the street, the young monk gasped as he saw a dementor slowly bending over the young girl who looked as she was unconscious. Joshua knew they were about to perform what they called, 'a kiss'. He felt a surge of guilt as he realized that there wasn't anything he could do to save that poor girl. For one thing, he had been strictly forbidden to meddle in anyone's matters by his master, for another, even if he were allowed, he didn't have enough power to fight off such powerful magical creatures.

Joshua had no other option but to watch in horror as the creature lowered itself to kiss that girl. He bit his lips and closed his eyes; this memory was going to haunt forever. Few moments passed and Joshua finally opened his eyes. The silence around him was unnerving. As he opened his eyes, he was shocked to see that the dementor was still bending over that poor girl. How long was it going to take? He wanted to go near and look, but he was sure the dementors will be able to sense his fear and decide to suck out his soul as well. He was lost in his thoughts when he received the greatest shock of his life.

From the mouth of the fallen girl, several wisps of golden light emerged and engulfed the dementor that was trying to suck her soul. There was a strange sound and the dementor caught fire. Joshua was wise enough to realize that it wasn't real fire but mystical energy. The other dementors circled the burning dementor as it turned into grey ashes and dissipated. The dementors flew away, apparently, to report to whoever had sent them about the mishap.

Joshua automatically took few steps backwards as the girl stood up. He could see her straightening her clothes and turning her head to see her surroundings. Her eyes were red and glowing so he can see them from a good distance. A twisted smiled appeared on that girl's face as she said to herself, "Of course, a little kissy wissy doesn't hurt anyone." The girl disappeared, almost giving Joshua a heart-attack. For the first time in last few minutes, he finally knew what he should do now; run to his people and inform them that's it's happening already, that they are back.

Sirius welcomed his childhood friend with a somewhat weary smile. Remus Lupin hadn't failed to notice this but he chose not to mention it and settled on the sofa.

Sirius ordered a house elf to bring them tea and sat on a chair facing his friend.

"So, what is that brings to this monster's lair, Moony?" Sirius sounded undoubtedly sarcastic. Remus sighed.

"I didn't assume you'd be still angry. And more than that, I didn't imagine you'd be mad at me."

Sirius and James had a row two weeks ago and weren't talking to each other since. Remus tried his best not to get involved but when Sirius seemed to be getting carried away, he had to step in and tell Sirius off for upsetting James. Remus really felt bad for James. He knew the effect living away from their only son was having on the Potters. Though they tried to act normal in front of their friends, Remus had always felt their pain in his own heart.

Sirius was glaring at him quietly. Remus wondered how was he going to react to what he was about to say. But he had to do it.

"Padfoot, listen, just forget about it, okay?"

"Yeah, right, that's what we're all supposed to do. Forget about things. About our enemies. Even about our children."

Remus shifted impatiently. It was a common knowledge that Sirius had never been able to get over Harry. It had been so difficult for Remus and James to stop him from going after Harry, or stalking him in his animagus form. He had always been against James sending Harry to live with that muggle couple.

"Sirius!" Remus was losing his patient, "This is about Harry, so you better listen, and shut this monstrous mouth of yours."

Sirius would've cursed Remus for repeating the same thing he had taunted him about few minutes ago. Remus had reprimanded him for having a monstrous mouth when he was arguing with James. Since he had mentioned Harry, Sirius was forced to listen.

"What about Harry?" He snapped nonetheless.

"Well, you know he's going to have his fourteenth birthday three months later."

"Thank you for reminding me that Harry will be spending one more birthday without us, with his fake parents, all thanks to you and Prongs." Sirius was spitting fire.

"No he's not." Remus said quietly.

"He's not what?"

"Not spending this birthday without us. We're going to bring him back."
