Prologue – A Dangerous New Foe

The first had long red hair and reddish yellow eyes. The second short green hair that spiked in every direction and greenish yellow eyes. The third, medium length straight blue hair and bluish yellow eyes, and the final one had white hair that was tied back in a spiky ponytail along with whitish yellow eyes. Hanging around each of their necks was a brightly glowing blackish yellow crystal.

"With these solid crystals of taint you are my strongest soldiers, so it is with you I leave a new task," continued the figure.

"I, Lord Shadow, command you to destroy the Seville family!"

Alvin adjusted his dark red tie and mumbled to himself. He hated wearing these stupid ties. Why on earth couldn't Dave have let him wear a shirt with his vest instead? Sighing, Alvin rubbed his paw against his crystal and breathed deeply as the familiar warmth of Lunarium flooded through his body. The last three months had been interesting for the entire family. Each of them had spent part of every day together, and the other part alone.

Dave, who had been surprised to be a new crystal wielder, had spent a lot of time alone with the guidebook. Slowly but surely he was getting better at tapping into Lunarium and using it. They were still unsure what the specialty of Dave's crystal was, but they hoped to find out soon. Dave had also been spending a lot of time with Theodore. Trying to keep him from realizing how worried they were about him possibly being attacked if he was left alone.

Theodore had been his normal self. Constantly wanting to be with his brothers and eat. Sometimes Alvin couldn't believe how naive and innocent Theodore was. But he loved his brother no matter how he acted.

Simon had, in his time alone, disappeared to an undisclosed location to train, and now his control over Lunarium was incredible. He could do things with Lunarium that Alvin had only ever seen Aaron do... which was good because his physical abilities sucked. But at least his control over his specialty was increasing at a decent pace. Simon's crystal allowed him to control water and, if needed, freeze it and wield ice as well. It had taken him some time but Simon could now freeze a shaft of water to use as a weapon.

Alvin though, had trained far more than Simon. Even though Simon's control of Lunarium was incredible, it didn't change the fact that he had barely any to tap into. Alvin had spent his time increasing his capacity again and again. He estimated he now had about half of what he had sensed Aaron giving off at full power. Alvin considered his training a success and, although he could not create spheres and waves of powerful Lunarium attacks like his brother, he instead focused on using Lunarium to enhance his physical speed and strength. He could move faster and hit harder than anyone should be able to.

But what had really come as a surprise to Alvin had been discovering his specialty. He had assumed it would be some form of physical ability to reflect his skills but he had been wrong, very wrong. His specialty was basically Telepathy. He could read minds and hear others thoughts. It had annoyed him greatly, yet at the same time been a point of interest in learning how to use it.

But of everything that had changed in the last three months, his relationship with Simon had improved the most. Sometimes it surprised him how much Simon would forgive him for now. Instead of instantly biting his head off, they would talk and try and see what had gone on and why. Alvin was becoming a lot more aware and considerate because of it. But one of the big changes in their relationship was the fact they were now sharing a bed.

They had both forgone sleeping apart and now spent every night together. The warmth and happiness they felt, far outweighed the awkwardness of the jokes and laughter Dave and Theodore subjected them to.

!KNOCK!

Turning around Alvin watched the door open and Dave walk into the room. Alvin was surprised to see an incredibly worried look on Dave's face. Frowning he opened his mouth to ask Dave what was going on, only to stop suddenly as he sensed it. Instantly knowing what Dave was worried about, Alvin transformed into his human form and snapped his fingers. Catching Aaron's sword as it appeared beside him in a flash of red light he focused Lunarium towards his leg muscles. Looking up at Dave he smiled and nodded.

"I'll go check," said Alvin before vanishing in a blur of pure speed...

Theodore stood calmly on the branch of a huge tree as he looked down into the clearing below him. His crystal was hanging invisibly around his neck, glowing slightly. His power capacity was nowhere near Alvin's, and his control of lunarium nowhere near Simon's, but he had more skill manipulating lunarium than anyone else, except maybe Aaron had. He had been in his dressing room when he had sensed the presence of a Tainted just outside the park where the concert was located.

He had waited until Simon noticed the presence and than Dave, who quickly told Alvin, who was the strongest. Alvin disappeared to go and destroy the Tainted and Theodore had followed him. He knew that both Simon and Alvin had been following him, to protect him from the Tainted. Neither of them were as good at hiding as they thought. It was kind of ironic though. That they thought they were the ones protecting him.

Anyways back to the matter at hand. He had followed Alvin to this clearing where he had immediately hidden himself in this tree. Alvin had drew Aaron's sword and looked back and forth in confusion. Theodore frowned slightly and looked to Alvin's right where he could clearly see the Tainted approaching. Sighing, Theodore tensed and prepared to throw himself forward, only to sigh in relief when Alvin flipped backwards and held his sword up against it.

Theodore knew that Alvin's senses were nowhere near even Dave's, but to not sense that Tainted until it was so close to him. He had obviously upgraded the Tainted to be more powerful. Also, judging by the fact Alvin was still fighting after a few minutes, it had obviously succeeded. Theodore closed his eyes and gathered lunarium into them. Snapping his eyes open Theodore saw everything that was, could be, or had been.

And he was worried...

Simon looked worriedly over towards the edge of the park. He was worried about Alvin. The concert was starting in three minutes and he still wasn't back. Simon couldn't remember the last time it had taken Alvin so long to destroy a Tainted.

Pushing his glasses up onto his nose Simon made his way towards Theodore's makeshift dressing room. Knocking on the door he waited a few seconds before it swung open and a happy Theodore walked out. Breathing in relief Simon gently guided Theodore towards the stage. Hopefully Alvin would be back in time to start with them. But if not they would just cover for him as best as they could.

Simon was so worried about Alvin, that he failed to notice the slight grass stain on Theodore's vest.

Alvin ripped the blade from the Tainted's chest with a wince. His entire body ached. He hadn't been forced to fight so hard in a long time. Since when had normal grunt Tainted become half as strong as a Corrupted for heaven's sake? Sighing, Alvin sheathed Aaron's sword and allowed the extra lunarium flowing through him to fade away. Walking out of the clearing he failed to notice as the body turned completely black and exploded in a rain of strange black energy.

Making his way towards the park concert, Alvin was forced to stop and look around a number of times. He was sure he could sense someone. But he couldn't see anyone and whenever he tried to lock onto who was following him they would disappear from his senses. Sighing, Alvin walked silently past security and towards the stage. Aaron's sword was sent away in a flash of red energy as he reverted to his true form and walked out onto the stage with a big grin.

His timing was so perfect that it appeared he had just been walking unnoticed behind his brothers. A brief embrace from Simon and a quick, "What were you doing?" from Theodore and they were ready to sing. Grabbing a small guitar from the stage hand, Alvin climbed up onto the massive guitar stage prop beside his brothers. Nodding at each other they looked towards the other people on the stage. A few seconds later Alvin and the others started playing their instruments, with Theodore and Simon humming quietly.

Smiling, he flipped backwards before jumping forward and climbing onto one of the human guitarists shoulder. Playing his guitar Alvin smiled and let himself fall into the song. He never felt more free than when he was doing what he loved. Jumping down onto the large prop guitar he slid down the massive guitar strings. Coming to a stop just in front of the crowd he carefully continued playing the guitar and winked at the crowd before staring to sing.

Girl,you really got me now,

You got me so I don't know what I'm doing.

Girl, you really got me now,

You got me so I can't sleep at night.

Jumping backwards Alvin ran back up the prop guitar.

Girl,you really got me now,

You got me so I don't know what I'm doing.

Oh yeah, you really got me now.

You got me so I can't sleep at night.

You really got me (Oh!)

You really got me (Yeah!)

You really got me

Climbing onto one of the speakers, Alvin began to play his guitar faster. Only to wince as one of the cords was cut by his claws.

"Nuts," said Alvin.

Eye's wide Alvin put the guitar onto his back and scurried to back stage. Rushing over to the stage hand he handed him the broken guitar.

"Gimme the black beauty," said Alvin loudly over the music.

Come on! Please, don't ever let me be,

I only wanna be by your side.

Come on Girl!

Please, don't ever let me be,

I only wanna be by your side.

The stage hand nodded and handed him a small black guitar. Nodding in thanks Alvin spun around and rushed back onto the stage. Only to stop suddenly as his cord was caught on something. Spinning around Alvin turned and found Dave standing on the cord.

"Dave, what are you doing?" questioned Alvin loudly over the still continuing music.

Girl,you really got me now.

You got me so I don't know what I'm doing, Yeah

Oh yeah, you really got me now.

You got me so I can't sleep at night.

Dave looked down at him with an amused expression, "Take it easy Alvin, those guitar's are expensive and this is a charity concert, so try..."

"Share the spotlight I know," interrupted Alvin.

Dave nodded happily and removed his foot from the cord. Smiling Alvin rushed back out towards the stage. Jumping onto the prop guitar and sliding to a stop in front of his brothers he seamlessly blended his voice back into the song.

You got me so I can't sleep at night.

You really got me (Yeah!)

You really got me (oh!)

You really got me

Eyes sparkling Alvin decided to do something just to annoy Dave. Throwing his guitar into the air he watched as it threaded through the scaffolding and came down hanging on the other side.

Tilting his head to look backstage he saw Dave standing wide eyed and shaking his head wildly. Ignoring him completely, Alvin bent his legs and charged them with lunarium before hurling himself into the air. The crowd screamed with energy as he caught his guitar and began to play it and sing while swinging through the air.

Ohhhh...

Oh! Oh! Oh! Oh!

Jumping onto the scaffolding Alvin swung around the bars as he played his guitar to the instrumental of the song, not even acknowledging Dave who was screaming for him to get down. Finally, deciding to at least try and listen to Dave, he looked down and his eyes widened in surprise. Standing behind Dave was the strangest Tainted he had ever seen. The Tainted had short green hair that seemed to spike in every direction and was wearing what looked like armor. Also, The Tainted was glowing with pure energy and, to Alvin's horror, he discovered he couldn't sense anything.

"DAVE LOOK OUT!" screamed Alvin

But he was too slow. As Dave turned around he had no time to react as the Tainted slammed a fist full of bright greenish yellow energy straight into his chest. Dave howled in pain as he was flung backwards across the stage.

"AGHHH!" he screamed.

Dave crashed into the other side of the stage and sparks flew through the air as a few pieces of equipment exploded.

"DDAAVVEE!" shouted Alvin jumping from the scaffolding and landing on the prop guitar.

Turning quickly, he faced the pile of electrical equipment that Dave had crashed into and started to move forward only to stop and spin to look for the Tainted who had attacked his father. To his surprise though, the Tainted had disappeared completely and he still couldn't sense anything. Hell, he hadn't even been able to sense the energy in the attack the Tainted had used.

Trying to throw those morbid thoughts from his head, Alvin rushed over to Dave and arrived just as the stage medics got there. He knew it was as bad as he thought when one of them pulled out their phone and called 911. Hopefully the day wouldn't get any worse...

As the people in the stadium panicked, a single armored figure in the crowd went unnoticed. He slowly made his way through the crowd with an evil smile firmly in place on his face. The elder Seville would not survive the attack he had hit him with. No one would be able to save him with the amount of power he had used.

Smirking he stabbed his hand through the chest of a foolish human who had been walking too slow and continued on his way. Only three more left and the world would easily fall to his master. After all, without Aaron, what hope did three foolish chipmunks and the rest of the weak human race have?

Laughing insanely, the figure vanished in a tornado of greenish yellow energy.

In the hospital, Dave didn't even notice as the doctor stuck a needle into his arm and gave him a powerful fast acting sedative. His left foot and entire right leg and foot were wrapped in thick white casts, as was his right arm. His neck had a thick brace around it and his head was wrapped with cloth. His chest had a large plastic reinforcement strapped to it to make sure his ribcage didn't move while he was healing.

He couldn't believe he had been attacked so easily. All that training, and he hadn't even been able to detect the Tainted or stop him from attacking! At least no one else had been injured though. Sighing, Dave winced and let out a hiss as pain flooded through him. His entire body ached and he wasn't sure if even with lunarium running through him if he would heal anytime soon.

Dave blinked and wondered if he would even be able to use lunarium while he was so injured. Smiling slightly, Dave wondered if the doctor would ask him what metal his necklace was made of eventually. They had tried to remove it and not even their massive steel cutters had been able to dent the powerful necklace ensured his crystal was not removed from around his neck.

"Here, this sedative should help with the pain," said the doctor as he removed the needle.

"I want to see my boys," said Dave.

The doctor's eyes widened, "Mr. Seville, I have just given you a sedative that will take effect in one minute...so, let them in quickly," he said turning to the nurse and nodding at her.

The nurse moved to open the door as the doctor moved to the back of the room to write some notes on a clipboard. Alvin, Simon and Theodore rushed into the room and jumped up onto Dave's bed.

"Dave! You're alive!" exclaimed Theodore in relief as he hugged Dave's shoulder lightly.

"Are you going to be okay?" questioned Alvin, looking away from Dave's gaze.

Alvin felt the worst about Dave being in the hospital. It was his fault Dave had been hurt. The second he saw the Tainted he should have attacked regardless of anyone seeing him. Now Dave had been hurt because of him... he couldn't protect anyone properly. Dave saw the look on Alvin's face and knew exactly what he was thinking.

"Alvin, it's not your fault. You can't protect everyone," said Dave wincing as pain flared through the hazy cloud descending over him.

"I know," whispered Alvin not looking like he believed a word of it.

"I'm going to be staying here for a while, so I want you boys to try and live a normal life while I'm gone. That's why I've enrolled you in school and called my Aunt Jacky to look after you," said Dave with a slight slur to his voice.

"SCHOOL!" exclaimed the three brothers simultaneously.

"Yes school. Simon I'm leaving you in charge...I'm...counting on...you," whispered Dave as his eyes closed sleep claiming him.

Alvin and Theodore were still too shocked about going to school to say anything. But Simon had never been more amazed. He had always thought Alvin would be the one left in charge. Especially with how mature he had been lately. Shaking his head, Simon and his brothers turned towards the door as a young lady holding a large bag walked in.

"I'm here to escort the chipmunks home," she said politely.

Simon and Theodore nodded before jumping off the bed and slowly moving towards her. But Alvin didn't move. He didn't want to leave Dave here alone and defenseless. But he knew he had no choice. Sighing, Alvin climbed down from the bed and followed the lady and Simon out the door. No one noticed as Theodore extended his claws and carved a few weird symbols into the doorway.

"Stay safe Dave," whispered Theodore before spinning around and rushing after his brothers.

Deep in the mist, a single figure struggled to move. His legs felt stiff and his arms heavy. It hurt to breath and every step he took seemed to become more difficult and painful than the last. But he knew he had to keep moving. Though he could not see where he was going he knew it was important to not stop walking.

Not that he knew why. He didn't really know anything. He didn't know where he was, what he was doing here, where he was going, who he was or anything. All he knew was that to stop walking would be the most foolish thing he could do.

He had to keep moving...
