At the Phantomhive estate...

Sebastian strode down the cold, dark hallway. Now that his young master was asleep and he had finished all his chores for the day, he was free to do what he wanted. His red eyes changed into hyptonising, demonic eyes as he dragged on a warm coat and black hat. It was time to do something about Grell. It could not go on any longer. The stupid bastard was always following him around, spying on his every move. He would teach him a much needed lesson tonight.
Opening the grand double doors of the entrance of the Phantomhive mansion, he slipped outside, closing it quietly behind him.

Outside, it was pitch black and windy. Sebastian pulled his hat lower to cover his glowing eyes in case some crazy human was still up and about at this dark hour, oblivious to the things of evil that dominated the night. There was no moon tonight - a dark mass of heavy clouds formed an unpenetrable prison, shielding him from the annoying light it reflected. He cocked his head thoughtfully and smiled. Crouching, he felt power build up inside him, and his seemingly human body started to transform.
Feathers, black and heavy as night itself, rained down from the sky as his eyes changed into glowing slits and his black hair extended down to his waist. Two black devil horns spiked out from the top of his head as the tips of sharp fangs, that glinted in the dark, protruded from his mouth. Angelic, black wings sprouted from his shoulderblades, sending out another flurry of feathers as he unfolded them and flapped them slowly. He stood up, much taller than before, as silver chains wound around his long body, making him look stronger than ever. He smiled, flashing his fangs. He felt better now that he was in his true demonic form. When the pure moon was hanging in the sky, casting its silvery light over the world, he could not transform, for its light made him weak and it exposed his true self to the humans, which would not have been very convenient for the young master.

Flapping his powerful wings, he rose steadily into the night sky, as shadowless as darkness itself. He was excited for the search as his hunting instincts awoke. Grinning with satisfaction, he plunged forward into the darkness, his wing beat steady and rhythmical. A bit disorientated from his recent transformation, he didn't realise that miniature masses of glowing greyness were following behind him, flitting and stumbling through the air on hideous bony white legs.

The chase was on.

A while later...

Sebastian scanned the forestry below him, eyes intent on catching a flash of red or a shine of steel. Where was the Grim Reaper? Usually, he was always here, sleeping high up in the trees, concealed from human sight. Now, he seems to have disappeared from this area. Suddenly, a high-pitched sound of an unpleasant mix of screeching and giggling filled the air, and his wings were suddenly caught in sticky, fluorescent green netting. With nothing to hold him up in the air and the net weighing down on him, he felt himself plunge downwards. Scrawny tree branches caught in his feathers and chains as he fell through the thick canopy of the dark forest and he landed painfully on the ground, scratched and bruised.

He cursed. Even though the transformation had made him stronger than before and heightened all his senses, he would also now feel pain - and on a much high scale than before. He grimaced as he fought to stand up, but the netting grew heavier on him as it pinned him to the ground. Groaning, he opened his eyes to see what had tore him, so viciously, out of the sky. He turned his head as he heard light, skittering footsteps and jittery voices filled the air.
There were four of them - slimy, grey balls each held up by six rotting legs that gave off a disgusting smell. A long, spiked tail grew out from each of the balls, and they moved in a jagged movement, as if they had been electrified. He could hear the squelch of slime and skin rubbing together as each of their solitary, flap of skin opened to reveal a blood-shot, bulging eye that swivelled madly in its pus-filled sockets. A small mouth surrounded by a circle of purple-veined tentacles vibrated and long strands of yellow saliva dripped from the small, fleshy hole. As gross as these strange creatures were, what caught Sebastian's most attention was the eerie fact that they all seemed connected in movement and thought. His hand groped for a pebble, and he flicked it into the darkness. All four heads turned at the movement, and all four eyes seemed to follow the path of the pebble as it sailed through the air in a neat arc. Sebastian squinted his eyes, thinking. This should prove to be an advantage in battle - if he gets out of the net in time. He studied the pulsing mass of complex ropes that wound around his body. There were little symbols on each criss-crossed rope and he froze with horror as he realised exactly what it was. The netting was no ordinary netting used by evil entities who just wanted to play around. It was a special kind of netting, used by the most qualified demon-hunters and made from the rarest of Araneus silk, Baetimus. Designed to absorb demon aura, he would have to control his power, hence preventing him from breaking out. He knew it was foolish to struggle, for the more aura a demon let out, the more stronger and painful the netting would get. He had no choice, but to call for help...but who? His eyes flashed a more intense red as he thought of his only option - someone who was connected to him by Spiritaemus - a connection only the most elite and civilised of demons share. He hated to call on him for help, but his young master could possibly be in deep trouble if he didn't get out of here... and fast.
Shaking his head in resignment, he rested his hand against the chains that wounded around his body, and a dagger materialised. He held it gingerly and rested the blade against his arm. Slicing it across his forearm, he gritted his teeth as pain lanced through him from the cut. He covered his index finger with black blood, as he uttered an ancient spell.

Somewhere in the world where Sebastian came from, a signal would be sent.

And then he would come.

In a realm where no human has ventured into and returned alive...

The sound of fetid water dripping into stagnant water filled the echoing silence, and the sound of the mutated rats' skittering could be heard. This was a dark cavernous space, filled with a confusing labyrinth of tunnels and hollowed out walls. White bones that stood out in the darkness were scattered across the dirty, black ground, encased in lava from an underground volcano that erupted some millennia years ago. A large throne stood at the centre of this maze of inky tunnels, surrounded by enormous crows and ravens that perched with beady eyes glinting in the darkness. Pale hands caressed a crystal ball that was emanating a soft light. Suddenly, it grew brighter, sending the perched black birds into a panic, and then died down suddenly to a steady, almost warm glow. Wispy strands of black, grey and white swirled slowly inside the globe, eventually coming together to form a clear picture.

A quiet chuckle came from the dark figure, his body lost in the shadows.

He spoke in a smooth and pleasant voice, not at all unfriendly. "Look at that pathetic little brother of mine...how could I refuse his sweet pleading for rescue? And oh dear...those things don't look too comfortable..."

He chuckled again, lips lifting in a smile. With a rustle of cloak against stone, he stood up, and the ravens and crows swivelled their heads to look at him obediently. He turned to them, hand stroking the nearest bird's head. "So, my sweeties...thisis what I want you to do next."

He bent down, dark hair falling over his eyes, and whispered to them.
