Fitz

Fitz is an oilman of the silo's down deep. He belongs to the crews that work the silo's lowest industrial levels, where oil is drawn and machines are fed, labor that breeds a particular temperament: practical, unsentimental, and allergic to being told what to believe. Fitz is a skeptic by constitution, the man in the crew who says what half the room is thinking and then watches how the answer lands. He is not a troublemaker so much as a weather vane; win Fitz over and the quiet doubters come with him. Like most of the deep floors' old hands, he saves his faith for what he can touch.
