[Nessin]

I'm building a background for my character (went with the basic Street Sam type using the concept of a Mercenary history), but my problem is I'm not too familiar with the ins and outs of Shadowrun's history, I'm working on it thought, just takes time to read through everything. Anyways, I was hoping somoene could give me some ideas to work with for now, until I learn enough to flesh it out in detail.

To start of with, he's a troll, and I've got nothing for his early years as a kid, but sometime in his teens he ran across a pit fighting match, and got hooked into that for a few years. After making a name for himself (just in his area) a mercenary company looking for more cannon fodder picked him out and offered him a job, gave him a cheap gun, and threw him in the front lines. From there he managed to survive long enough to equip himself far enough that should something go wrong (read, luck runs out) he could come out alive. Several years later and several augmentations letter, the small time merc company took a job out of it's league, most were killed, and those that weren't scattered. Which then leads up to now where he's on his own looking for work.
