Ok, so I beat Grizzlehiem, sort of. I beat everything EXCEPT for Ravenclaw. Ravenclaw was sort of it's own storyline, but just to make sure, will the storyline of Wintertusk continue on from Ravenclaw? I just want to know because Ravenclaw is hard and I can't beat it. So will any part of the storyline in Wintertusk will have to do with Ravenclaw? Thanks!

If you are referring to Ravenscar, then my guess would be yes you must complete GH as a whole in order to go to Wintertusk to continue the storyline that culminated in Ravenscar. As stated in the info release of Wintertusk, that it would continue/conclude the storyline begun in Grizzleheim.
