Brovo - LouisB3/Grannus-Expansion-Pack GitHub Wiki
Description
The second and largest moon of Sirona, Brovo is big enough to be a planet in its own right. Having a substantial atmosphere, and a surface colored in browns and beiges, it leaves us wondering whether Brovo is a rocky and dusty world, or a frozen world covered in ice. Or perhaps something unimagined?
