I.. err... missed that quest. First off, I travelled to Skellige prematurely, my intention was to do that quest but being a noob I couldn't find Faroe anywhere and ran around the main island in circles, not realising it was on another island!

So I gave up and made a mental note to try again after finishing the main story quest for Novigrad, to tackle it again when I went to Skellige. I ended up being over levelled, and since you don't gain any exp from being over levelled, I didn't do the quest. What sucked is it tied in with the main quest! Cause after a point it was cancelled out. I was thinking, **** I really should have done that! Moral of the story when playing TW3: do as many side content as you can as to avoid crucial moments in the main story.
