I have no clue where Felcandra can be though
felcandra blends in to the diffrent backrounds for example inside the dining hall on act 2 he can sometimes replace the wolf head with a Dalmatian and on the parapet he does the same thing replacing the piller of the wolf and most of the time on act 3 he becomes a bush shaped like himself next to Mathias in the courtyard. Hope this helps Nova
