What happens if you don't complete Novigrad's main quests?
It seems unnecessary to complete the Novigrad's main quest; the event with the most significance to the overall story line in Velen is seeing Uma, while the most significant event in the islands is finding out that Uma is important (which is a little sad that those are the most plot-relevant points, now that I think about it). So I was wondering, what happens if you just do Velen's quests up until you see Uma, and then complete the islands story line to the point where you see that Uma is important?
