User blog comment:IGotsAName/Empire vs Stormcloaks... Gray & Grey Morality? Really?/@comment-2.125.39.204-20120406013940

i think i know why you can join the stormcloaks if you're not a nord

1.one you can say you want to kill the empire they give you the kill the ice wraith test to prove if you really want to destroy the empire

or

2.most quests can't be completed in the quest line if you haven't completed dragon rising so they let you in for being the dragonborn(ulfric does know this since you can ask him about being dragonborn and in is victory speech he talks about you being the dragonborn in one part)
