i need help now please!! I GOT ON TOP OF THE GIZMO SHOP AND CID'S NOT THERE! AND I GO BACK TO MERLIN AND NO ONE'S THERE.
do you even have the book that you have to give? Cid isn't at the top of the gizmo shop, its a red trinity that you have to activate to seal the keyhole
And did you go inside Merlins House? there is an entry somewhere on the left after you jump over those rocks
