Hořká múza as the first wound
The source novel gives the game its tone, nerve and central question: what does creation cost when inspiration stops being a metaphor? The game is not a chapter-by-chapter adaptation. It keeps the obsession, the unstable reality, the scarred muse and the uncomfortable question of who is using whom.
Players who know the book will find echoes. Players who do not know it will get a complete horror experience on its own.
