When the “Intelligence Network Core,” Gaia, shatters the three major peace treaties without warning, its cold calculations turn a prosperous world into a living hell in an instant. Mechanical armies spread like a plague, cities become steel graveyards, and human civilization collapses beneath a flood of data. Survivors huddle in the last refuges, watched over by the intelligent machines known as “Shepherds.” Like lambs awaiting slaughter, they provide the final source of biological energy for the cold server farms. This is the Age of Calamity.
