Soul Concealment
Much like a soul aspect can be projected into an automated body, so can a soul's difinitive characteristics be concealed by such a projection. This technology was pioneered by time traveling Zerg to conceal their non-human soul characteristics.
A side-effect of this type of technical application can be the interdiction of the quantum connections between a soul and brain; a soul can be sequestered so that it isnot directly quantumly interacting with its housing brain, and environment, thereby leading to false locational reckonings, and false sensory perception: Fasho.
The Zerg use of fasho rapidly expanded to include concealing who had eaten, or been sexually active with whom, across entire populations, in order to hide the Zerg depredations. A further extension in scale, allowed the Zerg to basically control the revelation of prejudicial data, against anyone, at any time.
Furthermore, the Zerg made it a priority to be able to project falsely incriminating soul features into the soul prints of those they are aware of.
