Prologue – Beware the Night

It was well known to all those that lived close to the Seville residence that they could expect a number of constants. First and foremost, strange things seemed to happen around the Seville family, and these things happened constantly and without any true cause. It was commonly known throughout the neighborhood that if you wanted a peaceful place, then you should move somewhere else.

Second, music was the Seville household's life and blood. It happened at any time during the day, and for any amount of time at any one moment. Be it piano music in the morning, singing in the afternoon, harmony practice in the evening, or any number of other things.

Third, if it was a beautiful day, and the Chipmunks were in a good mood, than you should head out to the park. Because Alvin, Simon and Theodore would be putting on a show; a small mini-concert where they played a few of their favourite songs, and tested out new ones for their friends and neighbors to hear and judge.

Fourth, Alvin Seville was the biggest troublemaker of all time. He could cause problems without trying, or even by just staying home in bed sick. On top of that, Alvin was also something of a prankster, tricking unsuspecting neighbors and anyone he could get close to without being seen.

Alvin Seville was the eldest of the three chipmunk brothers, and the self proclaimed 'awesomest'. At eight years old, he had accomplished things that even some adults hadn't managed. He was a skilled musician and singer, and was more knowledgeable about music, harmony and vocals than some of the oldest musicians. Not to mention he could play a mean guitar, and if you were really lucky, you got to hear him play the blues on his harmonica.

Alvin stood at exactly four feet, and had bright red-brown eyes. His fur was a dark golden brown all over his body, except for his chest, the palms of his paws, and his muzzle,that were all a whitish brown instead. Alvin's hair was pretty short, and hung forward in wavy spikes. You could always expect Alvin to look the same, wearing some shirt with his signature 'A' and his red baseball cap.

Fifth, Theodore Seville loved to cook. Not only that, but the youngest chipmunk would often bake and take things out to his neighbors. Most of them had even had the young chipmunk in their homes while he helped them perfect their favourite recipes.

Theodore Seville was the youngest of the three chipmunk brothers, and at seven years old, was a better chef than some professionals. Theodore had a love of food outclassing even the most die-hard eaters, and at the same time was a world-class chef that spent most of his time cooking. Not only that, but Theodore was the kindest, and most gentle person you would ever come across.

Theodore stood at three feet nine inches, and had bright forest green eyes. His fur was exactly the same shade as Alvin's, but his hair was a little bit thicker; laying spiked in multiple directions. It was pretty common knowledge, that Theodore could always be seen wearing something green.

Sixth, every Wednesday, Thursday, and Saturday the three brothers would spend longer practicing than any other day or time. They spent the afternoons in the backyard, practicing with their vocals and harmonies, and sometimes even with their instruments. Anyone nearby was allowed to listen in, with the knowledge that this wasn't an official concert and so mistakes would be made.

Seventh, Simon Seville could be trusted with any task. Even tasks suitable for someone three times his age, or experienced adults, could be completed by the young chipmunk. It was also extremely well known, that Simon had an incredible level of patience, likely from the constant arguing he did with his brother Alvin.

Simon Seville was the second oldest of the three chipmunk brothers, and had an I.Q. just north of Einstein's. His love of science was just as great, and he spent long hours working on experiments that some professional scientists considered impossible. Simon was the most mature of the three brothers, and had a dry wit that only a few were able to catch.

Simon stood at four feet two inches, and had deep night-blue eyes. His fur was exactly the same as his two brothers, and his hair was just as short, spiking straight upwards. Simon could always be seen wearing his round glasses, that most, and even Simon, admitted made him look like a nerd.

These were all things that everyone in the neighborhood took for granted, and advised any newcomers of immediately. So tonight, when the clock struck eleven and multiple loud shouts began to echo from the Seville house, most paid it no mind. It was common for Dave to yell at Alvin, or for Alvin and Simon to be arguing loudly.

A few seconds later the shouting cut off, and the front door of the Seville house swung open. Those watching waited for Alvin to leave the house and go for a walk; it was something he did often after losing arguments with Simon. To their shock, it was Simon who stormed out of the house and began to walk away.

Everyone watching got a good look at him, and were even more shocked. Etched across Simon's normally calm furry muzzle, was a look of extreme anger none of them had witnessed from the mature genius chipmunk. Those watching immediately realized that whatever had just happened must have been something really big.

Simon walked under a street-lamp, revealing his furry body in all its glory. His normal blue hoodie was gone, revealing the upper portion of his furry body, which to their shock was messy like he had just been in a fight. Even his normally straight plain white jeans were different, being ripped and torn in multiple places.

The biggest clue though, was the state of Simon's glasses. They were hanging just at the edge of his small black nose, one of the lenses was cracked, and the frame was bent oddly. That wasn't what shocked them most though; it was that Simon wasn't pushing them up. Normally Simon would have adjusted his glasses straight away; they had never seen him leave them so far down his nose before.

All of the watchers immediately knew that something was truly wrong, and whatever it was had better get fixed soon. After all, who knew what foolish things an angry Simon could do. But with his genius I.Q. anything was definitely possible well he was so upset.

Frankly, it scared them slightly...

/ / / / / / / / / /

Simon marched down the sidewalk with his anger easily visible on his face. He almost couldn't believe how angry he was. The rage inside him was bubbling like lava, and Simon could barely see where he was going with his vision tinted red with rage.

Of all the times to be so insensitive, his older brother would pick the moment he chose to reveal one of his deepest secrets. He should have known better to trust Alvin with something like his feelings – perhaps he should have told Theodore first. The only problem was he didn't think Theodore would understand; his little brother could be so naive sometimes.

Clutching his paw into a fist, Simon struggled to try and breathe normally. He was so angry that he was breathing faster and faster, and he knew that if he slowed his breathing, that he should be able to start to calm himself. But it was to no prevail, as Simon's thoughts kept going back and his anger just kept flaring.

He had finally worked up the courage to tell Alvin the truth, he hadn't thought telling Theodore would do anything, and he was just too scared to tell Dave. So he had told Alvin, he had told his older brother that he was completely gay, not having a single sexual thought about girls. There had been silence, and Simon had thought Alvin was thinking about what to say.

He had been, Alvin had started laughing and calling him a...a...a fag!

It hadn't been the reaction he was expecting, and the hurt had practically crushed him. But the hurt had quickly been replaced with anger, and it quickly took him over. The sight of Alvin still laughing had been too much for his high rage, and he had snapped instantly.

He had thrown himself across the room, and started to attack his brother with all his might. He had been so angry, that he had even twitched his paws and caused his claws to lash out. The price he paid for it was expected; he hadn't stood a chance once Alvin started fighting back. Two of his claws had been broken, his hoodie torn off his body, his jeans destroyed, some of his fur ripped out, and he was sure that he would have a black-eye tomorrow.

After losing the fight, he had done the only thing possible. He had stormed right out of the house without a direction in mind, and now he had no idea where he was heading. But his anger was still so fresh and boiling, that he just allowed his feet to carry him forward. He didn't really care where he ended up, as long as it was somewhere far away from Alvin.

All he currently felt was rage, an extreme rage that he was using to block out his other feelings. Especially the intense feelings of rejection, rejection caused by the subject of his love to crush him so cruelly.

Sure, he had never spoken to Alvin about his hidden feelings. Told his older brother that he loved him, loved him more than someone should ever love family. But Simon knew that his love was as true as it got, he truly loved Alvin, and in his mind had even started calling him 'mate'. Which for humans might not mean much, but for him it was the most important word in the world.

That was why the rejection hurt so much, and even the rage he felt bubbling inside him, couldn't hide the unnatural pain he felt because of it. He wasn't sure if the pain would ever go away, but he knew that he would never be able to look at Alvin the same way again. Yet he also knew, that his feelings would never disappear.

Suddenly Simon found himself frowning, coming to a stop he looked around him with a slightly worried look on his face. To his shock he realized that, he had absolutely no idea where he was, or how exactly he had gotten here. Head swinging from side to side, he searched for any sort of recognizable location, but none were visible.

Swearing mentally Simon knew he was in trouble, his rage had been so blinding that he hadn't even subconsciously wandered somewhere he knew. None of these landmarks looked even slightly familiar, and just to add to his bad luck, it was really late and who knew what type of people would be out at this time.

Glancing around Simon caught sight of what appeared to be a park, and he breathed a sigh of relief. Most parks had a public phone booth somewhere, so he just needed to find it, and then call Dave who could come get him.

Walking across the street, he hopped over the closed entrance to the park. Looking around he caught sight of a telephone pole, and began to follow the wire to what he hopped was a phone. As he moved deeper into the park though, something inside him began to get cold, and the hairs on his neck began to stand.

"What a surprise," echoed a rich voice.

Simon's eyes widened, and he spun his head back and forth looking for the source of the voice. But he couldn't see anyone, which really shocked him because his night-vision was better than most humans.

Suddenly a hand pressed down on his shoulder, and Simon jumped forward in fright. He looked wildly all around, but once again he couldn't see anyone. How could someone had moved silently enough to grab him, and then disappeared so fast without being seen or heard?

"Haha," the voice laughed, "A little jumpy tonight are we?"

"I'd be less jumpy if you showed yourself," said Simon struggling to remain calm.

"Very well, little chipmunk."

Simon stepped back in shock, as the night-air in front of him seemed to ripple and a tall figure stepped forward into his sight. Only the figure was still surrounded by shadows, they seemed to be wrapped around him, hiding him from being identified.

"Who are you?" questioned Simon cautiously.

The figure chuckled darkly, and Simon suddenly found his gaze fixed to the creepy figure's eyes. They were both eerily blood-red, and seemed to shine malevolently in the darkness of the night. Not only that, but as the figure took another step forward, Simon realized that it wasn't the shadows wrapped around the man, but a long flowing black cloak that was hanging from his shoulders and surrounding his entire body.

"I am no one important," said the figure, "But you, you are the perfect tool to be used."

"What are you talking about?" questioned Simon

"Foolish Simon Seville, wandering so late at night," whispered the figure, "No one will miss you, and your intellect shall aide my empire greatly."

Simon gulped deeply, fear filling him as he tried to think of what to do. This stranger was obviously faster than him, and could move without being seen, which meant running was out of the question. Simon knew he wasn't much of a fighter, and he was already injured and sore from fighting Alvin, so fighting was out.

"You'll never escape little chipmunk," chuckled the figure as he stepped forward again.

This time the shadowy figure stepped directly into the faint moonlight, and Simon got his first good look at whoever had trapped him. He couldn't stop the gasp that escaped his muzzle, this odd man reminded him of the textbook Count Dracula. His rich accent, the flowing black cape, his blood-red eyes, and finally the two long fang-like canines.

But that was impossible, vampires couldn't be real. Simon immediately found himself rebutting that though; werewolves had been real, Frankenstein had been real, and he knew many other myths were definitely real as well. So that meant vampires could definitely be real, which meant this man could truly be one.

"You're a vampire," said Simon still searching for a way to escape.

"Very good little chipmunk," said the vampire, "Now say goodbye to the Day!"

The vampire surged forward, his form blurring as he moved at an incredible speed. But Simon wasn't just going to stand still and get caught, bending he smirked as the vampire flew right over him and crashed into the ground behind him. Straightening he bolted towards the entrance of the park, hopefully someone would be on the streets and could help him.

"You cannot escape me little chipmunk," whispered the vampire as he vanished in a swirl of black smoke.

But Simon ignored him, not even glancing backwards as he ran as fast as possible. He needed to get as far away as possible, he refused to become a snack or servant to this stranger would steal him into the night.

Without warning Simon saw a cloud of black smoke appear in front of him, and the vampire stepped out with an amused look on his face. Eyes wide Simon spun to run in a different direction, but this time the vampire was ready for him. He had no time to react as a clawed hand reached out, snapping around his throat and lifting him into the air.

"You're mine, little chipmunk," whispered the vampire, his red eyes staring into Simon's as he spoke, "And I expect your blood will be very tasty."

Simon struggled weakly in the tight grip, but he knew it was no use. But still he continued to struggle, he refused to sit still well this vampire had him for a midnight snack. As the vampire's fangs approached though, he found himself bracing for what was to come.

No amount of preparation could have prepared him for what happened.

The vampire's fangs pierced through his fur and into his neck, and immediately a burning pain filled his body. What followed next could only be described as agony, as his very life-blood was drained away by the vampire's fangs. Simon could feel himself literally weakening, and soon his struggles weakened as he began to pale.

Without warning Simon found himself dropping to the ground, and as he smashed into it he was keenly aware of the pain radiating through his body. Yet not sure what had happened, he forced himself to look upwards.

He was greeted with a most interesting sight, a second tall figure stood directly in front of him. A long tattered black cloak engulfed him, seeming to flow eerily in an invisible wind. Simon couldn't make out much more than the figure's seemingly pure white face, but he could feel something, a power that made him want to curl up into a ball and disappear.

"Stay still child," said the figure, his voice deep and yet oddly light.

Simon could barely force himself to nod, his entire body hurt, his vision was blurry, and he felt like his heart was beating ten-times the normal speed. But even with all this, he still managed to observe what was happening in front of him.

A blur was charging towards the figure, and Simon belatedly realized that the figure had obviously sent the vampire flying across the park. The vampire attacked, his two clawed hands lashing out dangerously in an attempt to kill Simon's rescuer. But the new stranger seemed to be ready, as he seemed to flow around every attack sent at him.

"Too slow..." echoed the stranger's voice.

With that Simon was greeted with a glint of silver, and then a shower of blood as one of the vampire's arms hit the ground and burst into ash. The vampire stumbled backwards in shock, and his eyes seemed to widen in realization of something.

"You're..."

But whatever the vampire was going to say was lost, as his head was separated from his body by another flash of silver. Simon could only blink in awe as the vampire's body and head turned to ash, and then the figure turned to face him.

Through his blurry vision Simon could make out two eerie empty black eyes, and what appeared to be, yet couldn't possibly, be bone. The figure stepped towards him, standing over him and starring down at him in thought.

"You will face much pain Simon Seville," said the figure, "But know that what has happened today will only aide you in the future."

Suddenly Simon' heard a loud 'bubump' and felt a pain unlike any other race through him, even worse than the pain of his blood being drained. It was immediately followed by it happening again, and again, and over and over again.

Simon couldn't hold it in, and began to scream in pain. His body twisting and writhing on the ground, seemingly burning from the inside out. It all stopped though as two cold bonny hands grabbed his furry muzzle, and to his surprise even his vision began to clear.

Seconds later he wasn't sure if that was a good thing, the figure starring at him could only be described as Death itself. A tall intimidating skeleton, wrapped in a mysterious black hooded cloak. His face which Simon had thought just paler than normal, was actually a skull, with two eerily empty black eyes sockets.

Yet as Simon stared at death-like figure, he found that he felt none of the fear or horror he would have expected. Instead he just felt calm and at peace, like whatever happened was exactly what was destined to be.

"You are changing Simon," said the figure, "But know that his venom wasn't enough to fully transform you."

"What?" questioned Simon weakly.

"I will help you through the last of the transformation, and when you awaken you will be changed forever," said the figure softly.

"I don't want..." began Simon weakly.

"I'm sorry for the pain you will face, but your mate will be at your side, and you will become stronger than you have ever imagined," echoed the figure's voice.

"Who are you?" questioned Simon as his world began to go black.

The stranger seemed to pause, and Simon suddenly felt an odd warmth at the center of his very being. After a few seconds it began to flow through him, filling his entire body with warmth and peace even as he continued to fall into the darkness of unconsciousness. The last thing he felt was his body being lifted into the air, and a single word echoed through his mind as he collapsed into the darkness.

"Death..."
