Jezero

Jezero is an arctic, exoplanet orbiting within the Gilese system. It is the only planet within the system considered habitable due to its tidal lock with its parent star and position within the habitable zone of said star. Jezero is the homeworld of the avian race known as the Sovani, and is known for its large exports of silicone and quartz.

Environment
The topography of "habitable" portions Jezero consist primarily of harsh tundras, covered in a dense layer of permafrost. Outside of these areas are super massive glaciers which dominate the remainder of the landscape. However, throughout these glaciers an intricate network of glacial caves sprawl. Within these caves exist massive crystalline structures compromised of naturally occurring silicone and quartz crystals. Deep beneath the glaciers, Sovani scientists have detected the presence of dark oceans, and an ecosystem flourishing off of chemosynthesis.

Kaggimiuk
The Sovani capital, and by far largest settlement on Jezero. While its size equates to only the size of a single, Terran Megacity (roughly the same diameter as the French Megacity) Kaggimiuk is incredibly well organized, clean, and safe. Built atop Mt. Kilak, the city enjoys a clear view of the horizon for miles in any direction. The city prides itself for its gorgeous scenery, as well as its efficient metro system that weaves through the crust of Mt. Kilak.
