Gal
A large gas giant approximately 122,000 km in diameter and 206 times as massive as Earth, Gal is the third planet from Gerrus, completing an orbit roughly every 393 days. It is believed to be a rogue planet, entering the system soon after planets began to form. As a result, many planetoids were swept into its orbit, either falling into Gal, getting ejected, or colliding to form larger moons. Eventually, the debris surrounding Gal formed four large moons in a stable 1:2:4:8 Laplace resonance; the rest consisted of asteroids in unstable orbits that usually wound up colliding with Gal or one of its moons or being ejected. Gal's four major moons are all tidally locked, with the same side always facing Gal.

Gal is whitish in color, owing to water vapor clouds in its upper atmosphere. Its orbital incline or roughly 24 degrees, combined with a speedy 12 hour rotation, result in magnificent bands across Gal, along with intense storms. The lightning from such storms can easily be seen from many of Gal's moons. Gal itself reflects a large percentage of sunlight, influencing the evolution of life on Xer.

In the early days of Xeverra space exploration, one of the main concerns was finding a way to shield machinery and personnel from the intense radiation produced by Gal's magnetosphere. Later on, it was skimmed as a plentiful source of hydrogen, helium and water vapor to be converted into fuel for outgoing and incoming ships. Its powerful gravitational pull is also useful in accelerating or decelerating spacecraft; ships can 'slingshot' around the planet to conserve time and fuel.

Brulik
At 6,800 km and .14 Earth masses, Brulik is the smallest of Gal's four major moons, though it is still larger than some planets. Due to the tidal forces of Gal and its other moons, Brulik is extremely geologically active, hosting hundreds of active volcanoes that eject gases such as sulfur dioxide and carbon dioxide daily. Most of these gases are swept away by Gal's magnetosphere, leaving Brulik with a thin atmosphere of ionized molecules and molecular compounds. Due to constant volcanism making exploration dangerous, Brulik was largely ignored by the Xeverra during early space missions in favor of Molla and Torred.

Molla
The second largest of Gal's moons, Molla is 8,500 km in diameter and .15 times as massive as Earth. Similar to Xer, it is an oceanic world, though it is distinct in the fact that it is far cooler due to a thinner atmosphere, barely averaging freezing. While it has its own magnetosphere, its ice-covered poles are left vulnerable to radiation, resulting in spectacular auroras. Beneath Molla's surface, an impressive array of aquatic life has developed; differences between Xer and Molla's equivalent of DNA indicate that they evolved separately.
