Terraformer

Terraformers were massive devices used in terraformation, which was the process of modifying a celestial object's atmosphere and surface composition to a condition suitable for habitation. It usually took around one hundred terraformers to fully terraform a planet within half a millennia. At least 12,000 planets underwent total terraformation throughout galactic history.

History
The first functional terraformers were developed by the Rakatans, who used the devices to terraform their own homeworld to make it render it hospitable due to an unstable atmosphere and later modified numerous celestial bodies to house their slave colonies. Millennia later, Human colonists from Corellia and Alsakan used these Rakatan terraformers to terraform several dozen planets during their explorations. The Duros as well as Coruscanti Humans developed their own terraformers and also led numerous terraforming missions over the ages. Around 7000 BBY, the Galactic Republic commissioned thousands of explorers to blaze hyperspace routes across the known galaxy and also assembled a fleet comprising hundreds of colony ships equipped with various terraformers and wild lifeforms. Over the next three millennia in what came to be known as the "Galactic Terraformation", these Republic explorers discovered hundreds of worlds, most of which were eventually terraformed. Other species such as the Hutts, the Columi, the Duros and the Gree also used terraformers in their interstellar activities.

Terraformation
The process of complete terraformation varied in efficiency between the technology used. A network of Rakatan terraformers across a planet could readjust a planet's entire atmosphere within one century, whereas a Corellian terraformer took on average 1,500 years of continuous use to completely modify the environment.

Variations

 * Auraformers were used to adjust a planet's atmospheric composition.
 * Lutumators were used to detoxify a planet's soil and distribute nutrients suitable for plant life.
 * Germinators were used to distribute plant, fungal, and bacterial life through the cultivation of various seeds and spores.
 * An astravillam was a germinator that was also equipped with a self-sustaining farm on which various species of mammals, avians, reptiles, amphibians, insects, crustaceans, and fish can be produced.
 * Aurastabilizers prevented a planet's terraformed atmosphere from being damaged or restored to its previous toxic state.
