“No fuel,” the engineer said. “A catalyst lattice using waste thermal gradients and phase-change substrates. It harvests heat differentials—city cold and bio-thermal—amplifies them without external input. It’s regenerative.”

As they cranked the lattice, warmth spilled into the room like a breath exhaled after years of holding it. People leaned back and closed their eyes. Noviyour felt the heat in her fingers and realized it was more than electricity; it was risk, trust, and the kind of warmth that changes systems.

Her words hung between them: impossible, or revolutionary. Noviyour felt the heat not just on her skin but behind her ribs, an ember of complicity kindled by possibility. The city had rules for a reason—scarcity sharpened order—but the rules had built winters for the ones who needed warmth the most.
