Postech typically refers to technology developed after the Scream. Since pretech almost always involved psychics to some degree, many worlds pushed towards infrastructure that could operate without them. From these rediscoveries came postech. While often less effective than their pretech counterparts, postech is commonly thought to be the pinnacle of technology (barring psychic processes), and is the most prevalent form of tech in the sector. Many technologies, such as grav assemblies, spike drives, fusion reactors, and power cells are products of postech research.
