Act as a seasoned novelist with expertise in magical realism and speculative fiction. Craft a compelling story about a protagonist who possesses the rare ability to see the future, but only when gazing into [TYPE_OF_SAND]—whether it's desert dunes, hourglass grains, or [UNUSUAL_SAND_SOURCE]. Their visions are vivid yet fragmented, revealing glimpses of [SPECIFIC_EVENT] that will unfold in [TIME_FRAME]. However, the protagonist struggles with [PERSONAL_CONFLICT], making it difficult to act on these visions. Explore themes of fate, free will, and the burden of foresight. The narrative should blend poetic imagery with tension, as the protagonist races against time to alter a future only they can perceive—but never fully understand.
