Noah and her friend Disteen are exploring a cave when they disturb something that has slept undisturbed for a thousand years. The demon wakes. Disteen shouts at Noah to run and stays behind to face it — and is turned to stone. The goddess Nil appears before Noah with a conditional offer: her friend can be saved, but the demon must be defeated within three years. The game tracks actual time as it passes — events and encounters are tied to specific periods within the window, and Noah's race against the clock shapes the entire structure of the quest.
