Synopsis：Ten years ago, Ethan Kane was a broke border‑colony mechanic, a low-tier citizen thrown into the Gray Helmet Suicide Battalion as expendable fodder against the Swarm. Everyone was certain the bugs tore him apart. They were wrong. Every “impossible” engagement he survived, every slaughter he turned into a victory, was quietly recorded in Alliance war manuals—credited only to a ghost: the Unnamed Marshal of the 9th Expeditionary Force. Now Ethan returns to a home in ruins: a wife picking through scrap to live, a crippled father spat on in the street, a daughter branded the traitor’s child—crushed by the mayor, the syndicate, and the very son who sold them all out. He came back for one purpose: to make every last one of them grasp exactly who they buried. And when the Swarm traces his trail and descends on the town, they will learn that the “deserter” they mocked was the only shield they ever had.
