Siirandra is a former mining outpost in the fringes of the Pentue Tahdet system. It was colonized in 3300, in midst of the largest interstellar conflict in Conglomerate history before the reconnection, as the need for new resources and metals grew exponentially, so having a mining facility in such close distance to enemy forces was worth the risk. During the first years, it also functioned as a small logistics bridgehead for navy forces, effectively contributing to the wellbeing and affordability of the mining efforts. Despite it being an inhospitable wasteland with a thick, toxic, and non-breathable atmosphere, its population and industry have grown massively in recent years. It mostly consists of Methane and Carbon dioxide with small amounts of sulfuric compounds, therefore making contained habitats and environmental protection suits obligatory. Despite these weaknesses, the relatively high atmospheric density, pressure, and inherently inert nature have some benefits for human colonization as well. The pressure is high enough to not need special pressurized vacuum suits and habitats, easing construction and living costs. The inert atmosphere benefits the main industry of the planet, ship deconstruction, repair, and refitting. Large and otherwise fragile components can be stored without the need for proper containment, and welding can be done with only very basic equipment.
Since the failure of several export businesses, targeting large habitat ships, the landscapes on the planet's surface are dominated by small hills and valleys, containing dome cities of various sizes and shipwrecks littered around them, waiting to be deconstructed. The largest of them are half-completed hulls of the Onaila-class habitat ships, big as mountains and halfway sunk into the ground, with heights of up to 3 kilometers and stretching across entire valleys. The first domes have been built especially near these resting areas, employing entire communities only to deconstruct them and to extract the valuable resources for later usage.
