Ever since the death of Presider Crostfree, the Pioneers were all facing a reorganization. Under Pridgeon's command, several new orders were issued, which improved on the security of the Pioneers and Presiders due to the sudden attacks and mysterious deaths of the Bringer of Change and the attacks made by the Lost Primordial and against the group who were believed to be against the Lost Primordial.
As such, a protocol was established to protect Pioneers in Australia. Pioneers could use no Aragarian techs for communication, and they would only use technologies known on Earth. An established code was set. Bringers of Change would contact one another, but this line is something that Presider Pridgeon could listen into.
However, in this protocol, Pridgeon could disconnect the line so that the line will not route to any Pioneers and to himself in fear of being discovered.
