The way in which the Zothyrians took over the control of the entire field of gnostic physics was by means of their magickal use of computer programming. They took possession of the field of magickal physics because they gradually took over every magickal computer in the universe. They simply started with one system and from that one system they moved outwards, from information system to information system, gradually changing the programs in other systems and computers, so that those programs and systems became subsections and components in their own logic. Their method of entry was entirely subtle and few if any magicians, even those using psionics systems, could detect the invasion from the outside. No one suspected such a move on the part of those who were 'others'.
