Cernunnos - LouisB3/Grannus-Expansion-Pack GitHub Wiki
Description
Falling short of planet status, Cernunnos is officially classified a dwarf planet. It is an icy world orbiting far from the warmth of its sun. Is it alone in this part of space, or is it only the largest of a family of small bodies orbiting on the outskirts of this planetary system?
