I once did it with the legend of the River‑Whispering Axe, and the event queue looked clean at first glance, but then the hero’s doubts turned into a separate state for every heartbeat, so the diagram grew like moss on stone. The architecture stayed tidy while the myth kept pulling in side quests that nobody ever reached, and that’s when the system felt over‑engineered. The code can stay clean if you keep the lore in a separate log, let the state machine handle only the concrete steps, and treat the myth as a narrative background rather than a functional driver. And every comma I put in the code feels like a breath of the forest spirits, so I add them with love but not over.
