Sand

Lore & Background

The behavior of sand in this world defies simple static classification. When piled high or confined within narrow shafts, the material loses its rigidity and begins to flow, mimicking the properties of a liquid. This phenomenon has led to numerous accidents where duplicants were trapped under shifting dunes or where essential pipes were blocked by sudden avalanches. Over time, colonists have learned to respect the granular nature of their environment, utilizing specific engineering techniques like sand traps and fluid locks to harness its utility without succumbing to its dangers.

In Their Own Story

The wind howled across the surface plain, kicking up a fine mist that stung the eyes. Kael adjusted his helmet seal as he watched the dune crest collapse inward. It wasn't an earthquake; it was just gravity doing what gravity does best with loose grains. A moment ago, the path to the new mining site had been solid ground; now, it was a cascading river of beige particles rushing toward the ventilation shaft. He didn't run—he knew that would only trigger more collapse—but he sidestepped quickly, watching his boots sink slightly as the sand flowed around him like water. 'Just another day on this planet,' he muttered, tapping his tablet to activate the emergency sand trap before the flow reached the airlock.

Reader's Guide

Sand is primarily found in the surface layer and desert biomes, often covering large areas of the map's upper crust. It exists at ambient temperatures but can become dangerously hot if exposed to direct sunlight or nearby lava flows. The primary hazard associated with sand is its flow mechanics. Unlike solid rock, sand will liquefy and pour through gaps in the terrain, potentially burying duplicants, clogging pipes, or collapsing tunnels. Large piles of sand should never be left unsupported above critical infrastructure. Extraction requires careful planning. Duplicants can mine it manually, but this often triggers avalanches if done from below. A safer method involves using a pump to extract the sand as a liquid resource, which allows for controlled transport and storage in tanks or pipes designed for granular flow.

Did You Know?

• Sand is the primary raw material required to craft Glass, a versatile building block essential for advanced technology.
• When heated to extreme temperatures, sand melts into Lava-like glass, which can be cooled to create solid structures.
• Sand piles have a specific 'flow threshold'; once this limit is exceeded, the entire stack will behave like a liquid regardless of its previous stability.
