Being completely new to the game, I randomly decided to help take over Whiterun for the Stormcloaks before I got a chance to finish the Companion quests. Does that mean that the Companion quests are no longer available? Are the options to marry the various Companion members still a possibility after taking over Whiterun?
(P.S. I am also wondering if it is possible to cure lycanthropy, aka being a Werewolf, after having taken over Whiterun. I know there is a way that involves one of the last Companions quests, hence why I asked if I could still finish that quest line after taking over Whiterun.)
Best Answer
You can still finish the quests for the Companions - joining the Stormcloaks and taking Whiterun actually has very little impact on practical gameplay, as it mostly just replaces some NPCs with some other NPCs, and some NPCs become happier than some others.
As for the second part of your question, you'll be able to cure yourself of lycanthropy as well, in the same manner that everyone else cures it (if you need a bit of help there, check this question out).
