Dust Crystallis: Fan-Built Sandbox RPG Where Time Has Frozen for 300 Years

A developer on DEV Community has published a detailed original worldbuilding document for an indie sandbox RPG concept titled Dust Crystallis, or Níng Chén Jì in Chinese. The game is set in a world where a catastrophic event called the Great Silence caused time itself to crystallize into a physical substance called Dust Crystal, freezing landscapes, oceans, and entire cities mid-moment. Players take on the role of rare beings known as Drifters, who retain living time within their bodies and can locally reactivate frozen time, harvest materials, and resist the world's creeping crystallization. The document outlines a full progression map, a resource system balancing life and energy, two-stage environmental hazards, and four major boss encounters each tied to the lore of the frozen world. The project concludes with three distinct story endings depending on player choices, including a secret ending unlocked by collecting scattered lore fragments throughout the game.
