In a basin surrounded by mountains, the only exit is a chain bridge hanging over a cliff. The outside of the village is shrouded in fog all year round, making it difficult for outsiders to find it.

The sword's energy nourished the land and made the villagers live long and disease-free despite poverty. But the sword energy gradually weakened, the fog began to dissipate, and the crisis was approaching.
