Story so far
Sevro arrives in the ash-covered Garter after helping force Athena and Volga's fleets to move in concert, delayed only because neither leader initially trusted the other. He embraces Darrow over Cassius's death and cries for the man who irritated him but had become part of the pack. His anger lands on Diomedes, whom he blames for letting Lysander go, but when the Hegemon says the lesson is learned, Sevro turns his contempt on Gaia and directs the group toward the waiting saviors rather than allowing old hierarchy to define the moment.
Sevro is present as the Covenant is forged, hears Athena's demand that Mars feed the Rim, and prepares to help Darrow make the mismatched fleet usable on its return. Aboard Archimedes, he stands with Darrow beside Cassius's funeral torpedo, recognizes Fitchner's old Ares helm, and puts it with Cassius before closing the coffin. He then brings Darrow to Cassius's small private room and, despite crude jokes, sits quietly to watch Institute footage of the three old boys together. The grief reveals Sevro's deepest loyalty: he remembers what it was to be lonely and recognizes Cassius as one of their own.
Appearance
A short, wiry, tattooed Gold with a restored warhawk haircut and a battered onyx Ares helm. He smells of ash and war, his feral manner softened by fresh grief.
