Terrarius V - home of the Terrarians, one of the most diverse races out there.
Taluth[]
Taluth is Terrarius V's first moon. It's generally a humid rock with very small and scraggly vegetation. The thicker atmosphere is rather combustible, and lighting a match would cause quite an explosion. The first rocket on it had to have heat shielding because of the immense heat produced from the fireball at takeoff.
Galith[]
Galith is Terrarius V's second, icy moon. Straying too close to its oddly composed atmosphere will cause a victim's instruments to be frozen within icy crystals, possibly damaging them. Probes are wrecked completely.
Galith's frozen mass protects Taluth from being bombarded and completely demolished.
