Ok so this story is essentially a 3 way crossover. It is a sort of Harry Potter/ Doctor Who/ Merlin crossover... It's under Harry Potter/ Merlin simply because Doctor Who only features slightly... But it's the principle of the thing.

So as much as I would love to, I sadly don't own the rights to Harry Potter (I've got the books but I don't suppose that counts does it...), I believe that's my idol J.. Doctor Who and Merlin both belong to the BBC as far as I can tell... So I don't own them either...

Prologue

The Angel knew nothing. It didn't know where it was, what it was doing, how it had come to be there or why it felt so alone and couldn't sense any of its fellows. It remembered the bright white light, the gap in Time, the agony of non-existance.

Now it knew only one thing. The Hunger.

Life. It sensed lives, young lives, full of so much potential... life. It sniffed the air hungrily, fixing its eyes on the large castle in the distance, winking in the moonlight. It was time for dinner.

Susan Bones was frantic. Term had only resumed two days ago yet she had so much homework to complete –an essay on the Unforgivable Curses for Snape (TWO FEET!), an essay for Flitwick on the revision of cheering charms (ONE FOOT NINE INCHES!) and a particularly nasty essay for McGonagall on the correct way to successfully transfigure an orange into a zebra- she had just put down the final dot-point for her notes on Snapes essay when she was mercilessly thrown out of the library by an irritable Madame Pince.

When she protested, Madame Pince slammed the door in her face saying-

"It's past Ten pm Miss Bones and I should have shut up ours ago! Even seventh years don't get that long in here! Come back tomorrow."

Scowling and mentally hexing the Librarian into a million slimy pieces, Susan stuffed her wand into her bag and stalked down the corridor. Now she had to return to the Common Room which, despite the late hour, would still be noisy! She sighed. There was no way she would finish Snapes essay tonight.

Out of the corner of her eye she thought she saw a shadow dodge past a window halfway down the corridor. She froze. It was quite dark along the corridor, all the torches seemed to have gone out.

"Hello?" she called hesitantly.

She received no reply. Plunging her hand blindly into her bag, while trying to penetrate the darkness, she found her wand. Clutching it tightly in her suddenly sweaty hand, she raised it.

"Lumos," she breathed, trembling slightly. Her wand tip ignited, flooding the corridor with light. It was empty. Empty except for her and an angel statue halfway down the corridor.

She frowned, cocking her head to one side in puzzlement. She was sure that the statue had not been there on her way to the library. She shrugged and turned around again, continuing on her way to the Common Room.

At the staircase however, she paused.

She shuddered as though she had just had an ice cube dropped down the back of her robes and the hair on the back of her neck was on end. Slowly she turned around, not knowing why she suddenly felt so uneasy.

She gasped and an icy wave of terror flooded her. The statue had moved! It was close to her, its hand outstretched towards her and a hungry look on its cold stone face.

She screamed. She turned and ran down the stairs, wand clutched tightly in her hand, bag bouncing off one shoulder.

At the bottom of the stairs Susan Bones' bag thudded to the ground, the echo of its owner's final scream ringing through the Hall.

The Angel was nowhere to be seen... and neither was Susan Bones.

A/N: So... if this story is favourably received I'll post the next couple of chapters. The inspiration hit me after watching the episode of Doctor Who entitled "Blink"... as it's a Merlin crossover and weeping angels zap you back in time and feed off your potential life force...you can see where this may be heading. But prepare for some twists and turns!
