I was a Nord who grew up in Cyrodiil. There came a time when I decided to finally set eyes on my homeland and so with a few fellow Nords, some Bretons and a few Imperials, we started off for Skyrim. We were barely a day into its border when a horde of bandits razed our tiny caravan. Some resisted but were put down. Eventually, those of us who escaped went our separate ways.
I happened to stumble upon a soldiers' camp a few days after the incident. They refer to them as Stormcloaks. I, for one, am not aware of the on-going Civil War so I figure them to be just some sort of independent army. The officer, seeing as that I was a Nord of able-bodied appearance and age, figured I was looking to join into their ranks. This was false as I simply was looking to purchase or trade for food and some other menial supplies for my journey.
That was when all Oblivion broke loose as legionnaires flocked the camp from all sides. The entire camp was taken by surprise and those who resisted were easily brought down by a hail of arrows. I desperately sought some shelter on one of the nearby trees but three legionnaires happened to subdue me with little effort, thinking that my treatment would be based on how I act.
It turned out that these Stormcloaks were branded rebels by the Empire and it wasn't surprising to find myself being labelled as one as well. I glanced at the officer by the large tent who had went down fighting. Then emerged a man I presumed to be a noble or of great importance, his hands raised in surrender as he was arrested like the rest of the survivors. They boarded us on wagons, hands bound and heavily guarded, as the convoy made its way to Helgen.
