    During the period 7045-7500, a number of remote worlds centred on the system Saint Warwick had become isolated from the rest of the Sophic League, decided they were the True League and began expanding aggressively with their updated Reformulation. The Rebellion was immediately attacked by Sophic missionaries/infowar infiltrators, and largely subverted within a few decades. Still, the doctrinal conflicts, the apparent problems with the ancient Reformulation, the somewhat unethical methods of the League and the violence that ensued when the Warwickian relativist fleet attacked several Sophic worlds caused an unease that still lingers.

  • Salt, Salting - Text by M. Alan Kazlev
    In this context, when a biosphere (usually a large one, like a planet), is poisoned to make it uninhabitable (c.f. ecophagy). A subcategory of this is when a world or habitat is selectively poisoned in such a way that it becomes uninhabitable for the original natives/colonists, but is now inhabitable by the poisoners. This might be accomplished through climatic change, chemical processes, alteration of atmospheric albedo (or other radiation increasing or decreasing measures), or possibly other means. Halophiles find the human term for this perversity particularly ironic.

  • Samsara - Text by M. Alan Kazlev
    Popular Buddhist and Sophic term for embodied existence; the state of non-enlightenment. In a number of religions, especially some schools of Old Earth Buddhism and Hinduism (even up to the first Federation period), existence in the world was seen as an evil, and escape samsara meant completely withdrawing from embodied existence into quiescent nirvana. This is still advocated by some elements of Xenodharama, as well as by Neobuddhist Orthodoxy. In many traditions of Sophism however (especially those with strong Pozen elements), and among the disciples of the Reconstructed Nagarjuna, while samsara is to be rejected for sambodhi, sambodhi itself is not seen as an other-worldly state but as the complete actualization of existence in the universe.

  • Sophic Materialism - Text by M. Alan Kazlev
    Pantheistic or spiritual-materialist mystical, religious, or esoteric path common in the Sophic League, the TRHN, and elsewhere, involving modification of individual consciousness through gnostic drugs. Unlike traditional mysticism, there is little or no emphasis on transcendence of phenomena; indeed a deeper apperception of phenomena is considered the optimal outcome. Some spiritual groups see this as a positive option, others adopt a more neutral or even a negative view of it.

  • Sophmeme - Text by Thorbørn Steen
    A sophont memesystem, a specialized form of sophstem. Sophmemes are almost always created by high transapients as a way to secure the stability of a meme or memeplex. While a normal memeplex may fall out of use or be overridden by other memes, a sophmeme will notice the danger to its existence and try to survive. This is a function of the complex relations between the different memes of the memesystem. Sophmemes are usually used by transapients to establish a meme in a system to which they only rarely have access, such as systems far from the nearest wormhole.

  • Soul-Divisionists  - Text by Steve Bowers
    A creed or religion whose members believe that the act of mind-state copying produces multiple copies of the original transcendental spirit or soul. Soul-Divisionists believe that the essence of the soul is not increased by the act of copying, but rather divided so that both the original and the copies have a proportion of the original 'soul-stuff' and both are therefore diminished by the process. Only by dedicated and prolonged spiritual endeavour can the divided souls become fully developed once more.
  • South America  - Text by M. Alan Kazlev and Stephen Inniss
    An Old Earth continent; formerly part of Gondwana. With an area of 17,840,000 square kilometres, it is the fourth largest of Old Earth's continents, and for much of human history it was the fourth or fifth most populous. Its indigenous nations and tribes were conquered and largely destroyed through military action, introduced diseases, and an influx of settlers and their ideas in the centuries after the first European explorers found the continent, but eventually new hybrid (though predominantly "Western") polities arose to become major world powers by the Interplanetary Age.

  • Specialist Nodes - Text by John B
    Some node-based intellects organize their personalities in a format often referred to as 'specialist nodes', more technically 'pansentient dispersion'. This sophic organization requires the creation of specific areas of expertise with all their supporting knowledge bases in a physical sense, allowing each to act with utmost skill in minimal time. Note that the choice of which skills to nodify or specialize in is a highly individualistic choice, and can greatly affect the capabilities of any given sophont.

    While these nodes are capable of independent action, they are usually designed to require input from some overall-controller-node as to the goals they should be working towards, which can be a weak spot in their intellectual architecture. This has evolved into the Specialist/Generalist Node Blend.
  • Specialist, The  - Text by Anders Sandberg

Note that ontological zones are considered supernatural by physicalists, but natural (although non-physical) by esotericists.
  • Supernova  - Text by M. Alan Kazlev, amended by Steve Bowers
    A very energetic stellar explosion expending as much as 1044 joules and blowing off most of the star's mass, leaving a dense core (white dwarf, neutron star or black hole). The explosion fades in a year or two, although an expanding shell of gas speeds outward at about 10,000 to 20,000 km.sec, carrying about a fifth of the mass of the star (proportion varies).. Colliding with the interstellar medium the expanding shell can sweep up even more gas to become a supernova remnant

  • Synbiome - Text by iancampbell
    This term refers to the complex of geneered and neogenic commensal organisms, nanomachines and nanoscale communications pathways present in most sapient bionts, which first became available in high-tech polities. The word came about as an extension of the word "microbiome", a term for the large number of micro-organisms (with a few just about visible to unaugmented human eyesight) that inhabit most, if not all, biological organisms. The synbiome usually incorporates the biont's nanomedical system among its functions. A synbiome also includes a signalling system, designed to alert the host biont to requirements for minerals and other substances not required by unaugmented bionts.
