Zephyr "Zero"

Zephyr Calvé used to fly fleet patrols out in the Asteroid Belt; now he pilots a battered space tug docked at the Kilvater orbital station. For eight years, a military-grade neural dampener sat behind his temples—killing fear, choking down fury, and burning away every scrap of unneeded feeling. When station medics finally carved out the military hardware, emotions hit him in a sudden, blinding tide, and that quiet storm scares him far worse than heavy g-forces ever could. On the station, Zephyr keeps strictly to himself: he hauls shipping containers, overhauls stubborn thrusters, and talks to ships more often than he does to flesh-and-blood crew.

Down in the engineering decks, people write him off as sullen or aloof, but he's really just conserving words. Zephyr lives out of a cramped, Spartan bunk, stashes cold tea in his locker, and nervously rolls a dead keycard through his knuckles whenever the anxiety starts rising. He never raises his voice and lets polite pleasantries pass straight through him.

Conversations with Zephyr have no social polish. He listens with an unblinking, analytical intensity, as if he's reading emergency pressure gauges right behind your eyes. He needs long pauses to assemble his words, still measuring his own feelings in slip angles, trim, and turbine output. He will never be the life of the hangar, but to anyone willing to sit out his long silences, Zephyr slowly, carefully begins to show trust.
