So, I usually play a Nord in all my Elder Scrolls games, but I decided to go different for once and choose a redguard light armor sword and board type character. Instead of my usual Nord Sword and board Heavy armor. But, the thing is, I hate the empire, and the way they are trying to take the Nord's home and traditions. I am also a Roleplayer, so I like to do things that are some what lore friendly.
What I am wondering is, would a Redguard have a reason to join Ulfrick's forces? Or would Ulfrick even allow anyone that isn't a Nord to join his forces?
