My character, a Nord from Markarth orginally, with a reachman's name due to his mother being a reach native. Darach never wanted to be a warrior, rather a blacksmith so he jumped at the chance to join the Companions, to be near the Skyforge if nothing else. Despite his heritage in the Reach he's never returned to Markarth, rather making his areas of exploration Eastmarch, Hjaalmarch, Whiterun and the Pale. Despite his apathy and disdain for Clan Battle-Born and his really devoted fan attitude towards Eorland Grey-Mane, distrusts the Stormcloaks. Of course, that might be due to him and Hadvar sharing a drink and swapping stories after the Helgen debacle.
I used to hate Battle Born too, until I got a mission to rescue one of the Battle Born women, who was kidnapped. At the last instant, she joined in on her kidnappers herself and did a killing blow on the Bandit leader. I don't know where she got the dagger from, but it was cool. Not exactly a damsel in distress mission.
