Lumi is a sparsely populated icy body encircling the ice giant Talv in the barren outskirts of the Tythel system in Midonia. The inhabiting people live in vast, open cityscapes excavated deep into the ice in order to protect against radiation. Sturdy, pressure-resistant mining sites have been constructed across Lumi's desolate subglacial ocean, excavating rare metallic ores to be processed in refineries built in the urban centers.

It is an icy terrestrial moon largely made up of silicate rocks and enveloped by a crust of water ice. Lumi appears as a white, slightly blue marble in space, interspersed by striking, darker lineae that stretch across the landscape. The gravitational pull of Talv has largely guarded Lumi against asteroid strikes, and subsequently, impact craters are sparse.

Infrastructure

Lumi's population resides in several vast cities excavated into the frozen terrain across the northern hemisphere, the ice acting as a cheap yet effective protection against solar radiation. They are constructed vertically, reaching hundreds of meters into the ice. In the center is a vast, open space used by businesses and surrounded by residential blocks.

Vibrant nature reserves have been constructed in every city on Lumi, flourishing with countless Kai Särav species, designed to help against the psychological hardships of constantly living in an enclosed space. They are enveloped by screens that accurately simulate the day and night on Kai Sära and are frequently visited by nearly the entire population.
