Umbriel is one of the Uranian Moons and is the main source of obtaining Drives without activating the Mothership. It is also one of the few places in the game to have a unique rock.
Appearance[]
Umbriel is a grey and black orb with a similar pattern to Iapetus.
Colonization[]
Colonizing Umbriel is easier than most of the Uranian Moons. The gravity is still an issue because it can fling you, but it has more plentiful resources than the other moons. It is also notably easier than Miranda, as despite the benefits of Miranda, it's gravity is pitifully low. The resources can result in very high metal and very high water, but there is no natural gas. Mostly the reason why people colonize Umbriel is to get Drives from Ball Lightning.
Ball Lighting[]
Ball Lightnings are special lightning bolt balls that can be found in Umbriel. Using an explosive charge on Umbriel will have a chance to yield a Ball Lightning, which then can be used as a resource for the Alien Processor to create Drives. Unfortunately, it cannot be used on Macerator.
