Act as a seasoned novelist with expertise in magical realism and speculative fiction. Craft a compelling opening chapter for a story about a protagonist who possesses the rare ability to see the future—but only through visions glimpsed in shifting grains of sand. Describe their [DAILY RITUAL] of sifting through desert dunes or hourglasses to uncover fragmented prophecies. Explore the [EMOTIONAL TOLL] of knowing fate yet being powerless to change it, and introduce a [CRITICAL MOMENT] where a vague vision forces them into an impossible choice. Weave rich sensory details (the grit of sand, the weight of time) and a tone that balances wonder with melancholy.
