A Type II or K2 civilization has control over their solar system, and may be able to harness all the power available in a single star. It extracts fusion energy, information, and raw-materials from multiple solar systems; it is capable of evolutionary intervention, interstellar travel, interstellar communication, stellar engineering, terraforming, and star cluster-scale influence; the resulting proliferation and diversification may negate the probability of extinction.


Energy usage: 1026 W to 1036 W. Total usage is the same as Type I multiplied across star systems. In addition: Dyson sphere, Star lifting, Dark Energy reactors, Industrial antimatter production and containment, magnetricity

Estimated Population: 100 Quadrillion (1017) people

Existence is in 4d (awareness of 5d) and 1r (reality)

Travel: faster than light devices, wormholes

Quality of life (government):

  • Adhocracy - flexible, adaptable, multidisciplinary government ideally suited to interstellar sprawl. Opposite to bureaucracy.
  • Post-scarcity utopia - achieved once the species is beyond interstellar barbarism and has settled into sophonce.

State of forms: hive minds (surrogacy or avatar)

WMD scale: Trinity project, monopole enhanced nuclear weapons

Longevity: 350 – 500+

Social issues:

  • Artificial Planet creation
  • Synthetic Life and possible AI dominance
  • Avatar prostitution
  • Manipulating the cultural focus of other species
  • Alien Propaganda
  • Trans-dimensional WMD
  • Dyson spheres
  • Dimensional portals
  • Transhumanism

Industrial revolutions: Warp portal, Dyson sphere, Galactic Exploration

Arguments: Synthetic life, Spacer psionics

Dominant proliferation: dimensional miscegenation cults, unified trans-human society

Social weakening: dimensional fallout or hyper radiation where dimensionally alternate 2d has disastrous effects on health (solution – Avatar allowing re-hosting of the contaminated)

Social dream: Eden or religiously motivated megastructure projects

Class system: Ideology meaning the general availability of superiority makes your motivations and commitments a value set
