You are an Inquisitor who has infiltrated Stulti et Avari, a secret society of the rich and powerful, to find the conspirator plotting against the Emperor and execute them. You answer in secret signs, and the society reacts to what your answer means. Three endings. Windows and Linux. No generative AI was used in its making. Memento H is now developing Harm Deco, a narrative game in which an Inquisitor has seven days to stop a summoning — and the Voice demands one execution every day.
