Here's my concept:

Jonathan Hawk was 20 when his life was forever changed.

Hawk was a mage, living in Seattle. He'd had his magical talent for several years, but had never really done anything with it. He was living an unremarkable life as a college student, major undeclared, no direction in life. He'd never even bothered to develop his magical skills; he wasn’t in the Thaumaturgical studies program, and had refused all corp-sponsored scholarships.

This all changed one night, when a car that Hawk was riding in crashed head-on into another car on a busy Seattle street. His friend, who was driving, was drunk, and he was killed instantly when he was thrown through the windshield. Hawk, in the back seat and wearing a seatbelt, survived, but lapsed into a coma.

The events that transpired in that coma would alter Hawk’s personality and life forever.

Hawk found himself in a horrible place. It looked like Seattle, but everything was different. The sky was orange and red, as though it were on fire. The buildings were all blasted, as thought something out of a bad 20th century nuclear Armageddon movie had hit the city. There were no bones, no wrecked cars, nothing to indicate that anything human had ever lived here.

It was then that Hawk first saw them. Strange looking creatures, down the street from where he was. He walked down the street to see what they were, but the closer he got, the more horrific they looked. Horrible, twisted monsters. They looked like they were once men, but had now been twisted by something. Their skin was all sorts of ugly colors, though each one only had one color – gray, oily black, sickly yellow.

The one commonality they all had were blood-red eyes. Eyes that were fixated on Hawk. Eyes that saw a meal.

Hawk couldn’t think of anything to do but run. So he ran. The monsters pursued him. It was as though the street never ended, and there was nowhere to escape to.

Finally, he saw what looked like a…rip. A hole in the middle of this realm. And on the other side, it looked like the Seattle John knew was on the other side. He wasted no time, diving through the hole. The rip closed once he was through.

John could still see into the other side, though. He saw the monsters congregating at the opening. And then, to his horror, he saw them trying to cut through it. Claws ripping, teeth tearing, they were trying to follow him. And even worse, the area around the rip started shaking, like a sheet of Plexiglass being punched. It didn’t give, but it was getting pounded…

That’s when Hawk awoke.

John came out of the coma to discover that two weeks had passed. Miraculously, he hadn’t suffered any brain damage, but he’d had other injuries.

Even worse, John remembered every detail of his dream. It all seemed so real to him. He didn’t dare tell anyone what he saw, but it stayed with him.

From that time on, John gained more interest in developing his magical skills. He practiced molding the mana into spells, and learned to conjure elementals to help him. His magical style involved Latin chants, and a somewhat Christian bent, even though he had never been a particularly religious man before.

Months after the coma, John saw something in the astral of Downtown Seattle, near where he had been hit, that terrified him: a fissure. It was tiny, barely noticeable, but it was there. Taking notes on the fissure over the next few months, he saw that it was growing. Its pace was glacially slow, but it was opening. And on the other side was the same orange-red fiery glow he had seen in the skies of that other realm he’d been to.

John had been convinced that he was in Hell during his coma. And now here it was, coming to Earth.

Since then, Jonathan Hawk has been a force against dark and evil magic-users, helping bring down wizzer gangs and other assorted magical bad news. His ultimate goal, however, is to find some way to halt the invasion from Hell he believes is coming. So far, he doesn’t have nearly the magical skill needed to even play a major part in any opposing action, but he’s constantly improving himself.

Name: Rand
Specialty: Sorcery Adept (Utility-type Spells)/Face (Leadership/Negotiation)

Rand grew up on the easy side of life. Not rich, but well enough to-do that he could survive comfortably with his friends and family. When his parents found out he could cast spells, they nearly handed him over to Humanis straight away. Only after running away into the Barrens and finding shelter under a gang with higher-than-normal magical ability could he escape. After years of training his abilities and coming up with a few others to aid in his survival, he led the gang out of the Barrens into the big time. Two years after that, he left them of his own accord to try to survive life in the shadows.

Shadow
Shadow is an B&E Expert, and a night elf. He is focused, charming, and sly. He uses a combination of cyber and old fashion cunning to cheat, steal, and rob just about everything under the sun. He runs the shadows to take care of his kid sister who he has in a private school.

Name: Jonathan Hawk
Occupation: Mage
Info: Jonathan Hawk is a mage, and ever since a car accident years ago, he's dedicated himself to stopping evil and dark magic users. The source of this mission lies in a car accident years ago, in which he was knocked into a coma. During this coma, his astral form was launched into a metaplane that Jonathan is convinced is Hell itself. His ultimate goal is to help stop an impending invasion from Hell that he believes is coming very soon. He would very much like to initiate so he can find that metaplane again and scout around, but the fact that he's neglected his magical skills for so long means that he now has a long way to go before reaching that mark. Even then, he will need much more training to make a difference against Hell's forces.

Year 2063.

Heya chummer. It's me, Winchy. Now you know how I came to be a shadowrunner. I might look like I'm all muscle and I'm not that smart but you shouldn't let this fool you. Every day of my life I have gotten smarter. Yes, smarter in my speach. Yes, a little bit smarter with the books. Yet, I'm sure there's a lot I could teach you even though you've read 100 times more books than I have. Cause the most important is that I've become much smarter about the streets and the shadows. You might be able to fool me with numbers or words, but never you will fool me in friendship, fighting, or money. And let me tell you this: in the world of shadows we're living in, these are the only things that ever matter.

And some anecdotes of his life in ...
