STRINGS.SUBWORLDS.NIOBIUM.UTILITY
By itself, Niobium is not a particularly useful resource. But if processed through a Molecular Forge, it produces the extremely thermal conductive Thermium, which goes a long way in solving many extreme temperature issues in a colony.
The edges of this biome are filled with Obsidian so a Duplicant with the Super-Duperhard Digging skill will be required before my colony can explore here.
