Solaria was a dome under construction at the time of the attack that wiped out the population of Farigha, as well as all but two of its habitats. Only Solaria and Landfall survived the attack. John Farno and his AI companion Persephone brought Solaria online and used its facilities to defend from further attack and to contact the Compact.
Solaria was intended to be Farigha’s first municipal-class dome, designed for the dome to be removed when Farigha’s atmosphere became hospitable to life. It could support a population of up to 2000 people when brought online.
After the liberation of Amargosa, Solaria became the capital of a fully colonial Farigha.
