Yuan Ti civilian leaders as per tradition fought in the frontlines in the war agianst Trokar and Aflua seeing the situation for themselves and not demanding sacrifices that they wouldn't make themselves Fertilizer produced as well as a source of prefabricated soil for urban agriculture in Yashuntai The Sheshagnite/Gayasite invasion of Freyaka took place at the same time as the preemptive Yashuntai invasion the Chief tchmutic preist at the time declared that the Freyakans destroyed the previous colony in Freyaka and ate the colonists alive and were the spawn of Ssrodna(the devil) urged soldiers to send Freyakans to Tchmut for judgement into Tchmutic hell and to show no mercy. Unclear if the Sheshagnites were this brutal Delpsans sacking cities with savagery could be a good enough explanation.
Sheshagnite invasion not long lasting as the 2022 map series stated the Freyakans repelled it. But defeating the Yashuntai buffer zone was harder During the creation of the military buffer zone there were Less atrocities then more Mass assassinations of elites, attacks on infrastructure as well as mass deportations of Freyakans from the buffer zone,As well as swarms of sky bombers, Shaysharic/Karshagian pirate expeditions utilizing thousands of ships and personnel Into Freyaka. As well as Military incursions from the buffer zone aiming at destroying and hunting down the Freyakan armed forces With enough speed as to accomplish the defeat of Freyaka before any orders from the 7 to stop could be given.There were Yuan Ti attempts to keep this secret from the tchmutic cult for as long as possible by controlling the Pan Eastronic flow of information This plan hoped that Tchmut would not inform on the Yuan Ti to the 7 Prophets.And that ths Sheshagnite Invasion would distract the 7 prophets.Tchmut and his 7 would then accept the capitulation of Freyaka as a fait acompli
