The Nupayuni Mining Consortium, a mining corporation linked to the Mining Guild, held the duty of developing the planet Crait. They mapped Crait during the era of the Galactic Republic, many decades prior to the First Order-Resistance War. To shield their activities from both periodic crystalstorms and sizable meat-eating carnivores, they erected a massive protective blast door. Nevertheless, the consortium soon ceased operations, and the Mining Guild chose to leave their machinery behind instead of funding a salvage crew, resulting in the group's departure from Crait.
