Gnuxox

Overview
Gnuxox ['nuzɑks] is the second planet from the star Echo of Adecomb. The planet is supremely hot, with an average air temperature of 112 degrees Fahrenheit and a record high of 238 degrees Fahrenheit. Additionally, the planet is wracked by severe dry electrical storms nearly constantly and the only native flora consists of a few species of cactus with poisonous fruits. As a result, the planet, though habitable, is extremely inhospitable, and all humans who live upon it must live underground, harvesting energy from the electrical storms to power air conditioning systems. Gnuxox has a vast system of underground lakes of average 18.5% salinity saltwater, from which humans living on the planet are able to draw water from, thus, desalination systems are crucial to surviving Gnuxox's conditions. The only prosperous settlement on Gnuxox is Cortora Mar, an energy farming colony of about 35,000 humans. Much of the planet's other ~5,000 inhabitants are either refugees, criminals in hiding, or exiles from Cortora Mar. The meager population of Tusgutta is made up of such people.
