Delmira

Delmira, or Craehlil II, is the second planet of the Craehlil System within the Orion Arm of the Milkyway Galaxy, orbiting Craehlil at approximately 0.72 AU. Known for its active geology, brutal tectonics, and semi-stable atmosphere, Delmira exists in a constant state of subterranean flux—wracked by frequent earthquakes, thermal upwellings, and sulfurous geysers that shape its fractured surface. Though technically within Craehlil’s habitable zone, Delmira is far from comfortable: surface winds are corrosive, storms are electrically charged, and its magnetic field is patchy at best. Despite these conditions, it remains semi-inhabitable, hosting a patchwork of shielded settlements, excavation domes, and research corridors primarily staffed by contract personnel and fringe syndicate operatives.   Delmira plays a vital logistical role in the broader Craehlil System, functioning as a relay and resource world between scorched Aul’Vex and industrialized Thauzuno. It houses multiple geothermal harvest arrays, deep-crust mining rigs, and hard-sealed data archives maintained by groups like the Halveris Arbitration Group and Axiom Dataworks. The planet’s crust is laced with heavy metals, thermogenic crystal veins, and volatile isotopes, all of which fuel its economic relevance. Though no native life exists, extremophile bio-constructs and adaptive nanite clouds are frequently deployed here to assist with subterranean extraction. Sovereign control remains decentralized—each outpost governed by localized accords—but all major operations require coordination with the Delmiran Extraction Syndicate, a fiercely protective entity with roots in old Vey’Zari mining cartels.
