A rocky, arid planet with deep canyons and sulfur deposits. Thin atmosphere (CO₂, SO₂), moderate gravity (0.8g), and one small frozen moon, II-A.
Planet III (Grasond)
Habitable, temperate-dry world with breathable atmosphere. Covered in vast elephant grass plains, high gravity (1.3g), and two moons with icy and rocky terrains.
Asteroid Belt (B)
Carbonaceous belt with abundant water ice, ammonia, and carbon compounds. Rumored to contain hidden artifacts and small abandoned mining stations.
Planet IV
Massive gas giant with colorful clouds and intense auroras. Surrounded by five rings and six diverse moons, including volcanic and icy bodies with potential for exploration.
Planet V
