Certainly I knew this since the first T.O.S. project, Illuminati, because of the similarities to Vengeance of Witches. If you look at the bottom tuck seals, they are even labeled as part of the same series. I don't have the decks in front of me, but I can check on the exact wording when I get home.
I missed out on Gothica because I was following Nicolai's main KS account but not T.O.S. (possibly because the second project under that name was not my style at all). I was planning to buy one or both decks when they are available on Isolated Thunderstorm. BTW, Nicolai and Marianne are partners in life as well as business.
