Authors note: To say this is my all time favorite anime, I've only seen seasons 1-3! I'm not sure if everything's entirely accurate, but I've tried my best. The digivolutions follow the simple: Rookie - Champion - Ultimate - Mega. None of that fancy Armor or bio-merge stuff. Some characters from the actual series will appear later!
All evolution lines should be correct with some explained spin-offs later. That's about it, hope you enjoy and please leave me some feedback!
Disclaimer: I don't own anything to do with Digimon.

Episode 1 - Trio

Part 1 - Introductions

The alarm clock speared straight through her dream.
A loud, un-merciful Digital noise that could only bring with it pain and suffering. The same sound which awoke her every day of the week. It signalled the start of the same routine, get up (slowly), get dressed, eat food, brush teeth, pack bag and go to school.
Amy let out a disgruntled noise and waved her hand to the right, a desperate attempt to shut off the alarm clock. Her hand however, met only air. Cold air, now that winter had fully set in.
Sighing, she opened her eyes, to find herself on the wrong end of the bed. Somehow she had turned over in her sleep. It certainly wasn't the first time it had happened; she had always been fidgety.
She moved quickly to the other end of the bed, trying to remain within the warm embrace of the covers as much as possible, and turned off the alarm clock.
There was a gentle breeze blowing outside. Amy opened the blinds next to her bed a tiny fraction, and much to her delight, discovered it was snowing gently.
"Not enough to get me a day off school, but it's good enough," she mused to herself.
She stretched on the bed, trying to get the sleep out of her bones, and yawned loudly.
She was protected from the cold floor by socks, and moved triumphantly to the mirror to see her shoulder length brown hair not as bad as it usually was. Feeling lucky, she smiled and changed her pyjamas for clothes that were suitable to wear in the public. The college she attended weren't fussy about uniforms for students her age, people doing their Advanced Levels, as long as they didn't look too 'bright' or foolish.
"Good morning Mum," she exclaimed as she reached the kitchen downstairs.
"Good morning dear, Becky already left early."
Becky was Amy's older sister, by two years. She had some trip to go on today with the school, Amy wouldn't see her till much later that day. Her Sister was a Teaching Assistant at the school and regularly helped out with the lower years.
Amy moved to the cupboards and took out a box of her favourite cereals.
"I'll get some milk on my way home from school," Amy said, after noticing the short stock.
"Thank you, that'd be helpful," her Mum replied, "So… how's Donald?"
Amy's boyfriend Donald; she had been expecting this conversation.
"Same old. He's getting stressed about his upcoming exams, he won't listen to me though," she explained.
"They never do, exams are more about the person, the most you can do is being there for him, he'll pull through; he's a smart boy."
Amy said no more on the subject, and the general chat moved to her own exams. She was in the final year of Advanced Level Study, and she'd taken Chemistry, Biology and Psychology as subjects. The only problem was that she had no plans for after the exams, a thought which constantly worried her daily.
As soon as she was finished eating breakfast, she sleepily returned upstairs to get ready for the day ahead.

Meanwhile, at the same school, Sofi was busying herself with piano practice.
She'd had to arrive early today, as it was the day of her practical exam. She had prepared three pieces for the examiner to hear, and hopefully, grant her a diploma.
She was satisfied with the first two pieces; the intricate melody work was bound nicely with fast-moving harmonies and powerful cadences. The third piece she knew would always be the one that would cause trouble for her. Apparently there was always a song, different for every pianist, which they'd never master, so her teacher told her.
Once again, she slipped up and broke her rhythm.
She still had four hours to go, which was separated by a single lesson. She hoped she would get it to at least sound fluent by then.
The door to the practise room abruptly opened, and Talyn walked in quickly.
"Trouble," he simply said.
She sighed, "Can it wait? I really have to practice."
He hesitated, "It's him again, Patamon's managed to defend without my help, I suppose I could go in alone."
"Call me if you need me," Sofi replied.
He nodded and left as abruptly as he'd entered.
She flicked through the pages of music and found her first piece. Even as she played it, her mind wandered to the Digital World. Another dimension she had first visited two years ago and then almost every day since. She had sworn to protect it, with her Digimon partner Lopmon. Talyn had also been chosen with his Digimon Patamon. It had been just the two of them, fighting off any evil threat that decided to challenge them. They had managed well enough so far, but she'd always had a nagging at the back of her mind that someday, they would face an enemy greater than the two of them could handle.

As was usual for this time of year, the school was hidden under a dark canopy of clouds. The snow had ceased falling half an hour ago, making the rest of her morning journey quiet, and darker.
She stopped upon entering the gates, and looked around the front courtyard. This was her last year at the school, after a long seven years of studying. She noted again the familiar faces of the first years, which were still full of glee and delight as they ran around; the less obedient second years, who had just entered the unwinding of their previously disciplined attitude; the moody third years, far into puberty, they were always the worst; the beginning-of-upper-school fourth years, who felt like seniors, but still had a lot longer to go yet; and the true-senior fifth years, who were close to choosing whether to stay on and do Advanced Levels or not.
Amy was drawn to the right, where her seventh year friends hung out before the bell sounded.
She noted the familiar faces, with just one absence. Her eyes met Donald's, and her heart flipped over. Unable to suppress a grin, she moved quickly and greeted everyone, hugging Donald around the waist.
"You have a music exam today?" Donald asked her quietly.
Amy was a flautist, who had achieved her grade 8 last year, "No, I didn't do the diploma," she replied.
She knew what he was thinking. Donald was an academic; he took every chance he could for better grades, to give him the best opportunity to get into a university. He would frown, as he thought she was wasting the opportunities, but Amy just didn't want to put the effort into something that her heart was not fully committed to.
"I'm not wasting it, it's not something I want to do, and it's a lot of money!" she complained.
He grunted, obviously not satisfied.
"So Amy, what about the party?" her friend Alice asked.
"Party?"
"You know, Isabelle's 18th! It's the big one, are you going to go?"
Isabelle Perkins, someone whom Amy didn't know particularly well. They had always been friendly acquaintances, and probably would stay that way too.
Amy hesitated, her friends would be there, plus other people whom she had known, but had left the school in the fifth year, she did like to go to parties, but Isabelle was the type who would issue a lot of alcohol.
The bell rang and interrupted her thoughts. Relieved, she moved with Donald and followed the mass of students travelling into the school building.

The bell rang. Sofi stopped her playing, feeling quite odd about leaving a song in mid flow, the sounds still reverberating around the room. But she packed away her things and quickly walked to her only lesson of the day, Chemistry.
After arriving five minutes late, apologizing and explaining to the teacher, she moved quickly to sit with the other four members of the class. Most had dropped after the sixth year, unable to hack the workload. Sofi wasn't surprised, Chemistry was a hard subject.
Sofi was a solid academic, but by no means a prodigy or genius. She got by well enough, finished all her work and understood most things easily.
"Good morning guys. Please turn to page 239; we're continuing our work on Inorganic Reactions. Does everyone have the homework to hand in on transition metal complexes?"
Mr Lee was a good teacher in Sofi's opinion. He was able to have a joke, and connected well with his pupils.
"Amy!" she whispered to the girl who was flicking through her folder next to her, "Did you finish it?"
Amy looked at her, "Yes, it wasn't that hard was it? I only found question 3 difficult."
Sofi smiled, "I thought it was alright, but can I borrow your rubber? My complexes got a bit messy."
Amy handed it to her, and just as she began scrubbing the messiest bits of the picture, the door opened as Talyn jumped into the room. He had been running.
"Sorry to interrupt you sir, the Head would like to speak with Sofi, it's a matter of urgency," he said panting.
Sofi was already packing her stuff away. She knew there was nothing the Head needed her for; this was a matter of urgency in the Digital World.
Mr Lee nodded and looked at Sofi, "You may go."
Trying not to run, Sofi quickly left the room; with the eyes of her classmates following her.
"What's happened? This had better be important," she asked in the hallway of the labs.
"Nothing bad, something quite incredible as a matter of fact, you'll see when we get there." was all Talyn said on the subject.
He was not the type Sofi usually hung around with, and they hardly did hang out in the real world, but Talyn was an efficient and powerful ally to have in the Digital World, and they got on better than she expected.
They had discovered a permanent route into the Digital World. It was hidden in the library, behind a broken book shelf.
Actually, the discovery had been quite bizarre. Sofi had first noticed it when a section of a bookshelf was missing, leaving a slim gap. The bookshelves were divided into rectangular sections of four blocks high, by three wide. On the second aisle, nearest the wall, one vertical section could be pushed into the next vertical block; much like a sliding doorway. Where the books went, they didn't know, but they always came back unharmed when they pulled it back across.
Talyn strolled in first, trying not to draw attention to either of them. Usually they'd split up and meet up in the secret room. They walked to the right, climbed the stairs to get to the second tier where all the Advanced Level textbooks and resource were stored, and they were hidden from view below.
Students coming into the library for work were not uncommon; there was always one or two in there at any time.
Talyn patrolled the perimeter, checking for anyone who might see them, whilst Sofi pushed the shelf aside just enough to let both of them through. It opened up to a dark room with a single desk inside. Upon which they had found a Digital entrance programmed into an old computer. As Talyn closed the shelf quietly, Sofi took out her Digivice.
"Ready?" she asked.
He stood next to her and nodded, placing a hand on her shoulder. They only needed one Digivice to activate the portal.
She pointed the orange and silver device at the portal, and it flashed green, signalling an opening. They both stepped forward, and a large flash erupted around them. The next thing they knew, they were standing in a forest, with a computer screen behind them, showing the world they had just come from.
"Lopmon, rally Patamon to our position," she spoke into the Digivice.
Their clothes changed as they entered the Digital World. She was now wearing an orange jumper with a large white scarf. Her skinny trousers had changed to a grey colour, and she had orange shoes on.
Talyn now wore a fitted black trench coat, under which was a black waistcoat, white shirt with black tie, and skinny black trousers with shoes. All in all, he looked like a detective, Sofi mused.
Why their clothes changed they had never worked out, nor why Talyn was dressed up smart. They assumed it was a reflection of their personalities, as neither had complained.
It wasn't long before Lopmon and Patamon emerged from the shrubbery. There was another figure with them, a rookie Digimon.
"Who's this?" Sofi asked.
"I'm Salamon," said the small beige dog figure happily.
"Salamon?" Sofi asked, looking at Talyn.
"Apparently she's looking for her 'partner'," Talyn explained.
Sofi paused, hesitating as realization dawned on her, "You don't mean?"
He was already nodding, "Yes, there is another one out there, and he's close."
