Definition: sophonts who have total dominion over a great many other sophonts of inferior toposophic, often ruling over entire polities, worlds, even empires
Includes: Toposophic dominion, imperial and other ai, posthumans and lesser ai, and other transapients. Also applies to ordinary sapients who keep subsapients as pets or servants, the subsapient is under the care of the master
Sentient Rights / Legal Status: Every Toposophic Sovereign is a law unto emself, at least as far as the beings under em are concerned. However it is often the case, especially in Sephirotic polities, that the sovereign is expected to treat eir charges, pets, and property with kindness; failure to do so may result in anything from legal charges being brought (centralist polities) to market boycotting (more libertarian NoCoZo and Free Zone regions, depending on polity)
Toposophics: SI:>1 (although in isolated regions there are some ordinary sophonts who have become sovereigns (nearbaseline autocrats etc))
Categories and Phyla: As far as sophont ownership, usually ai and po; however their are also slave-owning or harem-owning sapients of various kinds, especially away from the large centers of civilization.
Est. Percentage of Sophont Population: extremely small
Further Comments: The single most important factor in shaping the ecology of the colonised galaxy. Toposophic Sovereigns may rule through brute force, superior technology,or subtle memetic persuasion
Membranotoposophy - Text by M. Alan Kazlev Important subset of toposophy which maps transapient and similar cognitive states in terms of surfaces rather than as a linear scale or even a branching tree.
