Belisama - LouisB3/Grannus-Expansion-Pack GitHub Wiki
Description
Belisama is the lone moon of the planet Nodens, with an orbit that barely fits inside the small sphere of influence. A lesser body would have likely escaped Nodens's clutches eons ago, but massive Belisama clings so tightly to its parent that the two are mutually tidally locked, each always showing the same face to the other.
