The arrival- Prologue

Diagon Alley was silent; a damp mist covered the floor of the dark streets. All of the shops were closed, all waiting to be opened again first thing in the morning. The threat of the darkness was enough to keep everyone indoors….except for one person. The cloaked figure walked through the empty street towards the wizarding bank Gringotts. The mist swirled around the cloaked legs of the figure. It was midnight- the prefect 'witching hour' but this person had something much more important to a take care of. They soon reached the bank and one arm lifted up, revealing a slender leather gloved hand. The hand rapped smartly on the large doors once, twice, three times and the doors opened with no sound at all. The figure walked inside.

"Hello Griphook," The voice was decidedly feminine. The goblin in question merely beckoned her to follow him and led the way to the other end of the large entrance of the bank- past empty seats and high tables. They soon reached a door made of the darkest wood, which shone in the dim light. It opened and she entered.

"Ah….Serenity." An old wizened voice came from the dark and an old goblin leaned forwards to look at the cloaked figure. "Will you not reveal yourself?"

A small laugh came from the woman and the gloved hands reached up to pull down the cloak. Silver white hair tumbled from the confines of the hood- it was long, almost to the floor had it not been bound half in a bun on the top of her head. Silver blue eyes looked at the goblin before her head tilted to the side. "You haven't aged a day Runehook." A soft smile played over her lips.

"And you do not look a day older than the last time I saw you! How extraordinary!" Runehook looked at the woman who was supposed to look around 38 but did not look a day over 21. "I assume you have stopped ageing then?" She shook her head.

"No, I will still age. I just age gracefully that's all." An amused smile played over her lips as she moved to sit down. The whisper of silk was evident now as she moved- a red dress showing between the open folds of her black cloak as she sat. "But we did not agree to meet just to discuss my age. I am here to find out information- without that meddling old fool knowing about it."

"I quite agree. Well, I shall assist you as much as I can of course. We goblins owe you for your help over these last few years. Your protection on some of the vaults has proved invaluable." She gave a small blush at the praise but waved it off anyway. "Now, what would you like to know?"

"I want to know about Sirius. Is it true? Has he died?" Her voice held a hint of urgency and hope in it. She had known the man from Hogwarts. "You know we were close at the school, before I had to leave."

"I am afraid so." He watched her shoulders sag, and wished that he had some better news for her. "However, it seems he has fallen through a strange artefact." Her head jerked up.

"Artefact? What artefact?" Her voice sounded urgent, as if she knew what he was talking about, but wanting his confirmation.

"The wizards to not tell us goblins their business, you know this. I am afraid I do not know. But...I am sure his godson Harry Potter will know." Her eyes widened.

"Potter? Godson? You mean James and Lily married?" At his nod she gave only the smallest of gasps. "But, are they not alive?" He shook his head and her gloved hands moved to cover her mouth.

"You were unaware of this?" At her nod he proceeded to fill her in. Tears fell from her eyes as she listened to the tale. "I have the will of the couple here." He picked it up. "The old fool wanted it kept hidden and for good reason. He has put that boy into a home where he was not even supposed to go. He was supposed to live with either Sirius or yourself- if you were to return- or at the very least Remus Lupin."

Serenity looked livid. "Their son was sent to that awful sister of Lily's? How dare he?" Her eyes flashed in anger. "I will not allow such a thing to continue. Runehook, I want you to send a letter to Harry immediately. I will be picking him up first thing in the morning, and I would like to see those people try and stop me from doing it! Since Sirius is dead and Remus cannot look after him what with these idiot laws, I shall carry out my dear friends' last wish. I presume I was made godmother?" At his nod, she gave a decisive one of her own. "Its time everyone learnt that Serenity Moon is not a useless little girl as everyone seems to think!"

Runehook was already having the letter written out. It wasn't long before it was sealed off and sent by one of their owls direct to Mr Harry Potter. Serenity was not going to allow Lily's child to suffer any longer.

"I think I shall also pay a visit to this artefact at the ministry. I think I know what it is, and if I am right I will be able to return Sirius to us."

Runehook nodded in agreement before he paused. The elderly goblin looked at the woman. "What of you mate? Shall you also inform him of your arrival?" She paused and looked at him with a stricken look.

"He cannot know I am here yet. I am sure he already felt my arrival. But it has been years since we last lay eyes on each other." Her eyes dimmed in memory. "How can I know he still cares for me as I care for him?"

Runehook had the distinct feeling that there was more to this story than she was telling. However, he was not about to pry in her love life, after all, there was many things about the woman that no person knew. Or goblin for that matter. He truly wondered if anyone knew the whole truth about Serenity Moon. She was an enigma, a mystery that anyone would die to solve. She held power, of that he was certain, a power so great that it would give the Dark Lord power beyond his wildest dreams. He only hoped nothing would come to pass like that he feared.

Serenity was thinking. Could she seek her mate? The one she had waited for so long to see? She had dreamt of seeing him again, holding him, breathing in his scent. She longed to bathe in him, and rekindle the love that they had had for one another. She wanted to be with him again. She sighed, and mentally shook her head. She would sort that out when it came to it, until then she would take care of the matters at hand.

"Has the letter been sent to the boy?" She asked almost silently. At his nod she stood. "In that case, I shall take my leave Runehook." She gestured for him to remain sitting. "Please send word to my house elf- tell her that her mistress has returned and to make sure that one of the guest rooms is to be made up." She pulled the hood back up so that it covered her face. "It was good to see you again old friend, I will visit once again."

"I am glad to have seen you as well Serenity, please, contact us if you have any need of our services once again." He bowed his head to her and the large doors opened. She left swiftly.

She had much to be done, in a short space of time.

I know it's rather short but I promise a longer chapter next time Please leave a review.
