The three brothers—a pragmatic leader, a chatty second, and a simple, kind-hearted third—begin their journey with a clear, almost naive goal. They are not mighty. They are small snakes surviving on stolen offerings from villagers praying to the Dragon King for rain. The eldest understands a cruel truth: people worship power that solves problems. Their reverence for the Dragon King stems not from love, but from a desperate need for his rain. So, the snakes embark on a pilgrimage to learn this divine skill themselves.
