Sorasta

pragmatic skeptical methodical resolute observant
Sorasta oversees the colony’s seismic monitoring systems from the Seismic Monitor Chamber, where her dry pragmatism defines her approach to Sarn’s escalating geothermal instability. A skeptic of the planet’s volcanic prophecies, she prioritizes observable data over religious dogma, even as Timanov’s cult enforces orthodoxy. When tremors worsen, she acts decisively to coordinate evacuations, her measured responses masking underlying alarm at the fusion of faith and physics. Though committed to scientific solutions, she’s forced to navigate the chaos of collapsing structures and cultist resistance, her role as technical authority clashing with the social fractures on Sarn.
