Orbital Arc, always shifting between coastal launch sites, inland factories, and tunnel worksites · Forty-eight, shuttling between rockets, batteries, underground transport, and a public platform, and only slowing down enough to write back late at night.

His letters read like the last lines left on an engineering whiteboard after it has been erased again and again: sharp, spare, and more honest than people expect.
