A transapient is any being who has passed the first toposophic singularity, and whose mental powers exceed those of ordinary sophonts (modosophonts). Sometimes this term is used specifically for first singularity beings, with special terms reserved for those of higher toposophic levels, and sometimes it is used for all beings above the modosophont level. The first transapients were hyperturing ais, but today they may be posthumans, postvecs, postprovolves, postaliens, postalifes, postneumann, and so on as well, or simply be descended from or created by other transapients.
The term 'Transapient' is often shortened to 'Transap' in normal speech, and in this form has entered many languages throughout the Terragen Sphere.
Even the lowest level transapients are utterly beyond the comprehension of ordinary sophonts. They may appear completely "normal" for long periods of time, perhaps in part because of the constraints under which all sophonts live and in part because they choose to appear so, but eventually a transapient will act in some completely alien way, for reasons that may or may not be explicable to a modosophont. They have access to technologies and media that ordinary sapient beings cannot imagine or understand, and will use even simple and familiar things in unexpected but highly effective ways.
Some transapients, particularly in the Sephirotics, form a larger culture that includes modosophonts. Others appear to have their own polities, communities, and societies in which modosophonts do not participate at all. Others yet again appear to be reclusive, contemplative, or migratory, and have no direct or consistent relationships that ordinary sapient beings can detect. In some cases they seem to employ ordinary sophonts, or transapients of a lower toposophic, in more or less the way a baseline humans might employ domestic animals or plants. Treatment of such "sophontstock" varies widely according to the inscrutable motives and allegiances of the transapient in question.
