A po; any entity of S1 or greater (AI, posthuman, postxenosophont, postvec, etc.).  A godlet; a being of high singularity (generally S2 to S3) toposophy. A being of inconceivable intelligence and capability, self-evolving, self-constituting and from the point of view of ordinary sapient beings unlimited. Powers are intermediate between standard super-intelligent transapients (lower transingularity) and archailects (higher hypersingularity). Often they are completely enigmatic to those sentients below them. In some cases, powers serve as mediators between the archai and the superintelligent and subsingularity beings (as seraiph for example), while in other instances they follow their own independent evolution and development. There are believed to be several million powers in existence through the Terragen Sphere.
Postalife - Text by M. Alan Kazlev An alife who has attained transingularity status. Even by S1 and higher standards, postalifes by their very nature are quite variable - much more so than posthumans. Some are not too dissimilar to standard S1 posthumans and hyperturings, while others are very alien indeed. Some postalife are defined as animin.
Postbiology - Text by M. Alan Kazlev Biology and ecology of postbionts and/or postalifes.
Postbiont - Text by M. Alan Kazlev An organic lifeform that has attained S1 or higher. May be an ascended sophont being, or even an ordinary sub-sapient organism that was somehow infected with or modified by a godseed. The term is generally used to refer to those individuals that have retain a (modified) carbon-based organic body.
