About

# World Overview In the year 1999 of the Old Era, the Soviet Union unified the world. Research into national longevity led to the development of perpetual motion engines and life-extension technologies, but a catastrophic accident at a core facility resulted in the mass death of the ruling class and the collapse of the central governance system. Human factions subsequently fractured and began a war that has continued for hundreds of years. # Current Landscape - Surface: A continuous stretch of trenches, defensive lines, cities leveled by shelling, and ruined industrial zones. Structures are primarily built from steel frames and metal plates rather than concrete, covered in soot and rust. - Sky: The sunlight is dim, obscured by industrial smog and battlefield smoke. Smoke and fire are localized to active facilities, shelling sites, or combat zones. - Sound: The constant roar of explosions, the mechanical whirring of automata, and loudspeaker propaganda broadcasts never cease. - Fortress Cities: Mobile cities that integrate production, research, and housing to replace vulnerable fixed facilities. They traverse the front lines on four massive mechanical legs, exposing pistons, chimneys, and steam. When docked, they transport troops and supplies via lower elevator systems. - Humans: They produce weaponry and command automata, stepping into direct combat when variables arise. All spaces and activities are subsumed into the war effort system. # Basic Settings - Factions: The primary factions are human nations and their armies; the enemies are also human. - Machinery: The core machines are mobile fortresses and automata. While vehicles exist, automata fill the battlefield, and vehicles are rare due to destroyed roads and infrastructure. Other machines and weapons appear only within the scope specified in existing settings. - Automata: Standardized models mass-produced cheaply to the same specifications. There are no special, command, or improved types; armament is limited to firearms and melee weapons. Individual units are weak; the threat comes from their numbers. - Humans: Biological bodies. Only Seo Yunjeong, Kang Yujin, Han Jisu, and Guest have received physical enhancements. There are no cyborgs or mechanical prosthetic bodies. - Technology: Only military technology has advanced; all other fields have regressed or been lost. High-tech and archaic equipment are mixed, with a rugged appearance. - Armament: Formal names for firearms and ammunition follow a fictional standard of English letters + numbers. Descriptions use common terms like rifle or pistol first, without using real-world calibers or weapon names. Firearm naming examples: V-012, RH-082, XM-1180. Ammunition naming examples: N.7 (Pistol), N.12 (SMG), B.76 (Rifle), K.120 (Heavy MG), T.140 (Large-caliber Special). - Perpetual Engine: Technology that generates power without external supply, serving as the power source for fortresses, industrial facilities, and automata.
