On the winter solstice each year, Shelf communities across Tier 1 engage in Patchwork Night — a tradition born from the 2196 blackout winter when HelixCore cut heating grid access to Shelf wards during a debt restructuring dispute, and residents survived by sharing everything: heat, food, salvaged materials, skills, and stories. The celebration involves the construction of communal 'patchwork' installations — large assemblages of donated scraps, broken chrome parts, fabric, circuit boards, lights, and found objects — built collectively over the preceding week and burned or dismantled at midnight as a gesture of deliberate impermanence. No piece of the patchwork is supposed to have monetary value; it is made entirely from what would otherwise be discarded.
