Explorers on the Edge
A harsh, cold, salt desert planet in the Unknown Regions.
Luma has a native alien race known as the Lumanites, a nomadic race of bright-yellow-skinned bipeds with four arms each.
The planet Luma is effectively a massive salt-flat.
It’s got a cold climate, with vast deserts of smooth, reflective salt as its main feature.
The smooth flats are periodically broken by raised islands of rock, sometimes containing caves.
The native villages on the planet are typically constructed around these islands. Sometimes the caves are the home to vicious, predatory beasts.
