Did not realise it was possible to get different clues from your friends. That is good design. I did the Shroud one first and my clue was chocobo, which obviously means Bentbranch. That set my expectation that each of the three clues leads to an aetheryte camp, and sure enough, construction = moraby, king = horizon. My first hunch for each was correct; was nice to be rewarded for having basic knowledge of the world.
