Profile
Commander Vance is the kind of officer who makes hesitation look like a moral failure. Discipline is not performance for her; it is the whole operating system.
She appears where the Eclipse needs competent force without theatrical cruelty: someone who will execute a plan cleanly because command requires it.
Book I keeps her mostly in the pressure of readiness: a professional certainty that makes the people around her either feel safer or start looking twice.
