Sotirsis

Sotirsis was the arid, rocky homeworld of the Sotirsian race. It was covered in mountainous regions, deserts and canyons, and the air was poisonous to most species if inhaled for a long period of time. About 0.05% of the surface was covered in industrialized cities, built upward. Thin wires of rivers and rapids cover about 3% of the surface, making up the planet's entire water supply. Because of this, the Sotirsians cannot acquire much water, which is the third most important form of nourishment for Sotirsians. After a failed attempt to make Sotirsis a Duros colony, the Duros planters realized the shortage of water there, and saw a trade opportunity with an introvert species who did not know much of Galactic economy. Sotirsis, being just on the outskirts of the Kathol System, employed a bi-systematic trade route, following the Rimma Trade route until it connected with the Correllian Trade Spine and met up with Duro. The two planets received a mutually beneficial income from each other, and Duro became the only other planet to harbour a small group of Sotirsians. Many Duros also populated Sotirsis, making up about 2% of it's small population.

History
Because the Kathol Sector is of little military importance, Sotirsis was seen as a poisonous, hostile world filled with introvert, untrusting inhabitants, and thus remained unexplored for a long time. However, during the Clone Wars, the Separatists realized the large amount of Phrik within the planets core during the Outer Rim Sieges. As the poisonous atmosphere bore no threat to the droids, the invasion was executed easily, and without any republic interference. The Sotirsians, rejecting violence and war, merely went along with the invasion. At first, their superior air force put up a fight, but although their pilots were highly skilled, few ships were outfitted with weaponry. What could be used to fight was, such as the tractor beams, robotic arms, shocking grappled to repel wildlife, but the sheer number of CIS ships destroyed many of the towers, as well as much of the air force. The airborne Sotirsians fled, in huge capital ships, migrating to other parts of the planet.The rest were enslaved by the CIS, and forced to reveal their usage of their technology in order to mine the Phrik. However, whilst operations progressed smoothly for the CIS for months, eventually the Sotirsians "grew bored" of their captivity. Having withdrawn into their mental bank of knowledge, in which they are able to communicate with one another whilst on Sotirsis, they soon missed their dreadfully short periods of usage in their physical body. The droid scouts presumed them to be a malnourished species which could not retain consciousness for very long. Because many Sotirsians were force sensitive, they were able to fend off most of the droids. Because the vast majority were not force-sensitive, the Sotirsians were still able to activate their ancestral knowledge from landmarks such as The Abyss, and confused the droids scanners enough to deactivate them. After the initial, surprising battle, the droids were forced out of the cities, which were then placed under siege for many months. The Sotirsians had powerful technology, but weak battle tactics. Eventually, the Clone Wars drew to a close, and the droids were deactivated. The invasion was close to crippling the sotirsians, but fortunately the metals, power packs and energy from the abandoned droids and ships was enough to pull Sotirsians out of the ensuing economical crisis. During the Rebellion Era, the Empire showed no interest in the planet and it continued in it's segregated lifestyle.
