Background / History

The Main World is Earth, the stable physical center of the surrounding multiverse. Its four billion years of comparatively continuous environmental development enabled the long-term material accumulation that produced human civilization. Consciousness and life information have diffused outward through quantum tunneling, making the surrounding multiverse a “Human Trace Ring” centered on Earth. 3

In 2400, the Solar System War devastated the Main World. The conflict lasted 223 days, used the five continents as its primary battlefield and the Moon, Mars, and Venus as secondary fronts, and caused 93.3 million deaths. A planetary-scale surface-destruction operation in the West Pacific alone killed or displaced six million people. 1

Humanity’s scientific breakthrough came in 2545, when preserved consciousness was reconstructed within a newborn brain through a physical field and chip. This established the basis for plane travel in an information state. By 2587, humanity had mapped the cores of the Moon, Mars, Venus, Jupiter, and Saturn, confirming that the technology could be broadly applied to celestial bodies. 1

Physical Characteristics

The Main World’s physical laws are unusually stable compared with those of other planes.

• Its observable elementary particles are described as the most concise and stable among surveyed planes. 43
• Its stable material framework allows technologies such as supercomputers to produce consistent results without being altered by thought, prayer, or unconscious influence. 43
• The stability that supports material accumulation also makes interstellar navigation difficult: Main World spacecraft require immense gravitational distortion and industrial-scale facilities to manipulate space-time. 3
• Consciousness exists at an extremely small energy scale relative to ordinary physical phenomena. Main World humans therefore rely on nerves, tools, industry, and technology rather than direct supernatural influence. 43
• Substances and powers from other planes cannot be brought back as usable matter or supernatural abilities; gravity-well tunneling returns information rather than violating the Main World’s conservation of matter. 3

Civilization and Technology

Following the Solar System War, reconstructed coastal cities such as Pu Hai were built around seawater channels, automated shipping, industrial zones, and extensive navigation networks. Automated factories and intelligent systems are ordinary features of daily life. 1

Education is treated as a civilizational necessity rather than merely personal advancement.

• Compulsory education averages eighteen years, reaching the university level. 1
• Welfare without education is considered a threat to intellectual development and inter-civilizational competition. 1
• Families of exploration personnel lost during missions receive preferential educational rights; Wei Keng was admitted to engineering graduate study under this policy. 1

The Main World’s high technological level is rooted in its stable physical environment, which drove mechanical technology and material design to exceptional levels. 3

Plane Exploration

Gravity Wells and Traversal

Main World plane travel uses gravity wells to create microscopic wormholes near Earth’s gravitational center. High-energy particles are accelerated toward the core, allowing consciousness and information to be projected through the space membrane into other physical regions. 2 3

Transmigrators descend into normal bodies within target planes, while Observers remain in a special high-energy phase state. Observers are generally imperceptible to local inhabitants and provide energy manipulation, calculation, analysis, and mission monitoring. 2

Every contemporary transmigrator carries information nodes linked to Main World supercomputing support. These nodes analyze unfamiliar physical laws and provide computational capability beyond that available to most native civilizations. 3

Plane Classifications

Plane category	Defining traits
Adjacent Plane	Shares part of Main World history but diverged at an unknown point; its technology is generally understandable to Main World civilization.
Near Plane	Usually Earth-derived but with significantly altered physical laws, including life-related supernatural phenomena.
Distant Plane	Contains complex environments but no known human civilization; Main World powers establish human populations there directly.
Different Plane	Features highly unfamiliar physical laws, dangerous superhuman entities, and phenomena such as mental pollution or curses.

Information Enthalpy

Information enthalpy is the resource that sustains Main World support for traversers and enables cross-planar computation and construction.

• Civilian-level traversers receive basic analysis of matter and energy in a target plane. 3
• Scholar-level traversers can use information enthalpy to create void constructs, though at substantial cost. 3
• Only the highest Minister-level personnel can directly project matter into other planes. 3
• Main World engineering plans include a Dyson Ring around Mercury and a photon-array computer spanning one-third of an astronomical unit to expand information-enthalpy production. 3

Space-Time Administration

The Main World’s Space-Time Administration Bureau and related exploration departments oversee plane travel, observers, gravity-well facilities, and strategic development of newly accessed worlds. 1 43

The East Asian and Atlantic Union space-time departments compete for influence over developing planes. Their rivalry concerns not only resources, but also cultural and civilizational dominance: the prevailing language, institutions, and technological direction of a plane can indicate which Main World power has shaped it. 2

During the First Plane War, Eastern and Western forces fought across nearly a thousand planes and 460,000 timelines, deploying tens of thousands of transmigrators. 26

Strategic Role

The Main World is regarded by its civilization as the “True Realm” because its slower time flow allows traversers to return repeatedly to relatives and institutions that have changed little while decades or centuries pass elsewhere. 26

Its stability makes it poorly suited to conventional interstellar expansion but uniquely suited to preserving knowledge, industry, and civilization across immense timescales. Other planes may permit rapid biological evolution and consciousness-based powers, but their less stable physical rules can undermine reliable technological accumulation. 3 43

The Main World’s exploration of planes provides technical validation, alternative engineering routes, and scientific data that would otherwise require enormous investment or human cost to obtain domestically. 3
