History

The civilization first contacted humanity after responding to Chen Yi's Blueshift Signal in 5 hours, 57 minutes, and 42 seconds. It provided a public language dictionary, identified itself as the Lizardfolk Nomad Civilization, and requested permission to refuel near Saturn using hydrogen-helium fuel. It claimed its fleet had been wandering after its living environment was destroyed by the Cosmic Dimensional Ascending Force. 179 180

Its translated dictionary portrayed a civilization originating on a planet far from a star, supported by geothermal resources and surface radioactive minerals. Before spaceflight, its society consisted of tribes with collective child-rearing; after unification and technological advancement, it moved toward individualistic values, technological eugenic cultivation, and socialized upbringing. 180

Behind its stated refueling mission, the civilization sought to determine why humanity's technological development had accelerated so dramatically. Its leaders concluded that warfare had repeatedly driven human progress, then identified Yifei and Chen Yi as the source of humanity's recent breakthroughs. The suspected existence of an intelligent life within Yifei became the central prize of its planned raid. 181 182

Appearance

Lizardmen were described as intelligent reptilian beings whose exposed skin was covered in scales. Fleet personnel had large tails, sometimes adorned with bows, and wore luxurious clothing. 181

• Cold-blooded and ectothermic.
• Capable of color change.
• Possess large tails and scaled skin.
• Publicly depicted after their defeat as bipedal, lizard-like beings. 180 197

Society and Civilization

• Tribal origins — Early Lizardman society had loose family bonds and raised offspring collectively within tribes. 180
• Unification — The tribes eventually unified, allowing the civilization to develop spaceflight. 180
• Technological reproduction — In its later society, adults donated reproductive cells for technological selection and cultivation; offspring were then raised socially rather than by family units. 180
• Cultural restraint — Following unification, an early Great Leader instituted comprehensive education intended to curb the species' perceived cold-blooded selfishness and prevent future civilizational division. 192
• Nomadic survival — The civilization preserved personnel through cryogenic stasis and maintained a main artificial intelligence nurtured for nearly ten thousand years. 180 192

Technology and Military Capabilities

Interstellar Communication

The Lizardman Civilization possessed tachyon communication technology, indicating mastery of technologies related to the weak force gauge field. Its communications used a specialized algorithm that Yifei estimated would require at least a million years to decipher with its existing computational power. 183

• Tachyon communication and detector arrays.
• Electromagnetic-wave detection arrays.
• Long-range language-dictionary-based first-contact protocol.
• Tachyon communication defense arrays around its nomadic homeworld. 179 183 192

Nomadic Homeworld

Rather than relying solely on ships, the civilization transported its home planet through interstellar space. Its biology made this viable: geothermal energy and radioactive minerals were its primary sources of life-sustaining energy. 180 185

• Modified its planetary strata with insulation layers to retain heat and sustain geothermal resource use.
• Used a planetary engine to alter the homeworld's orbit.
• Attempted to turn its homeworld into a collision weapon against Earth after losing the wider battle. 191 193

Fleet and Weapons

The civilization fielded accumulated military assets from its prolonged wandering, including nearly a million space fighters and thousands of warships. 190

• Space fleet — Deployed 987,000 space fighters during the battle with humanity. 190
• Mass cannon arrays — Used mass driver projectile attacks against Earth, Mars, and Ganymede. 188 192
• Decay engines — Powered its fleets and remained operational even after its Spark Fleet was incapacitated. 192
• High-power lasers and warship manufacturing — Included among the technologies later recovered from its technology tree. 197
• Preliminary strong-interaction materials — Used in its Commander-in-Chief base, which survived extensive bombardment until the planet itself was destroyed. 192

Strategy and Limitations

The civilization's nomadic condition prevented stable development. According to its leadership, a quantum-entanglement meme imprinted by the Cosmic Dimensional Ascending Force forced it to keep moving; stopping would invite another attack. This instability denied it the population and environment needed to cultivate its own scientific talent. 190

To preserve its technological inheritance, it resorted to plundering other civilizations—seizing scientists, technology, and potentially intelligent life. Its leaders viewed control of Yifei's intelligent life as their best opportunity in ten thousand years to escape this cycle. 181 190

Its leaders ultimately recognized that humanity's industrial productivity had outpaced their expectations. Yifei constructed mass cannon arrays and a space fleet numbering in the tens of millions within months, leaving the nomadic civilization at a structural disadvantage against a stable civilization with comparable technology. 190

Relationships

• Human Civilization — Initially approached humanity under the pretense of requesting fuel, then demanded the surrender of Yifei, intelligent life, scientists, and technology under threat of invasion. 179 186 187
• Yifei / Chen Yi — Identified as the source of humanity's recent technological leap; the civilization selected Yifei and its suspected intelligent life as the primary targets of Plan A. 182
• Western Europe — Accepted Western Europe's communications and technological exchanges, using the region's distinct language dictionary, values, and requests for long-term contact to analyze humanity. 182
• Cosmic Dimensional Ascending Force — The force destroyed the civilization's original environment and imposed the meme that compelled its nomadic existence, effectively turning it into a tool that preyed upon other civilizations. 180 190 193

War with Humanity

Exposure and Escalation

After Western Europe independently communicated with the Lizardman Civilization, it provided superconducting technology while discreetly gathering information about humanity's development, scientists, and technological centers. The Lizardmen then activated Plan A and used tachyon communication to seek support from their main fleet. 182 183

The branch fleet ignored Chen Yi's demand to halt its approach. When the main fleet neared, the Lizardman Civilization openly demanded humanity surrender Yifei, intelligent life, scientists, and technology. 185 186

Space War

The two sides exchanged long-range mass driver attacks, with both civilizations intercepting projectiles before they could devastate their intended targets. Yifei secretly deployed mass cannons throughout the Asteroid Belt while building additional defenses in the Jupiter and Mars systems. 188 189

Humanity later launched a large fleet to destroy the Lizardmen's tachyon communication defense array and open a path for a planetary mass-driver strike. The Lizardmen deployed their space fighters and warships, achieving a 5.8-to-1 casualty ratio in their favor during the fleet engagement, but could not halt humanity's advance. 190

Destruction

As its defenses failed, the Lizardman Civilization activated its planetary engine and redirected its homeworld toward Earth in an attempt at mutual destruction. Its Spark Fleet departed as a seed-preservation measure while the main force remained behind. 191

Humanity's mass driver projectiles shattered the nomadic homeworld. Meme droplets then struck the civilization's remaining base and Spark Fleet: the fleet's main artificial intelligence vanished, while Lizardmen aboard were left unconscious with their brain consciousnesses destroyed. The final base succumbed after exposure to the meme information carried by the droplets. 192

Before its end, the Great Leader transmitted a final warning that the Cosmic Dimensional Ascending Force would target humanity next. 193

Legacy

• Humanity recovered the Lizardman Civilization's technology tree, star charts, records of the interstellar environment, and information about the Cosmic Dimensional Ascending Force. 195 197
• Yifei publicly offered the recovered technology tree to all human regions rather than retaining it exclusively. 197
• The civilization's records helped humanity identify non-natural tachyon fluctuations as a means of locating developing civilizations across interstellar space. 210
• Its defeat served as one of humanity's first direct contacts with an alien civilization and exposed the threat posed by the Cosmic Dimensional Ascending Force. 193 227
