Crystalline Plains

Detailed geological surveys of … have revealed rivers of semi-frozen ammonia flowing beneath its frozen crust. Rising geothermal pressures drive this substance through fissures in the brittle surface. These eruptions spew a volatile mixture of hazardous vapors and ammonia slush across the surface of the planet. Refreezing as it becomes exposed to the extreme surface temperatures, the slush forms sprawling plains of easily harvestable and valuable crystals.

The command below will trigger the "Crystalline Plains" event in Stellaris:

When this event fires, you can choose between the following option:

• Fascinating.
  • Add deposit: +2
  • Add deposit: +1

Stellaris events fire in chains — one event leads to the next. Here is how Crystalline Plains (extreme_frontiers.320) connects.
