a specific part of the game, related on the Cultural Traits (Tratti Peculiari) came from another concept I was thinking about. This concept was suggested to me during a trip to Val Seriana, during the listening of the music album The Last of Our Kind from The Darkness. In Particular the prhase "defenders of the legacy" in the song "Last of our kind"
