Prism of Fear

The story revolves around an ancient being called the "Fear Prism" - it is not a ghost or a demon, but a "conceptual fear" that spreads according to specific rules. Whenever human beings violate its thirteen original taboos (such as "Counting the stairs alone at midnight will lead to more steps", "Answering the non-existent voice to the reflection", etc.), It will tear open cracks in reality and drag the victim into a "prism of fear" based on its deepest fear.
