In the backdrop of the Grand Betrayal, Frankonia's longstanding mission to the
Kang was imperilled. A number of diplomatic staff were implicated as Templars and executed, though the Enduring Avatar of the Kang Dynasty had had enough, and used the Templar infiltration as the basis for expelling all Frankonian personnel from the Mandate. This was backed by military force, which ended in a month-and-a-half-long siege of the Frankonian legation. In the end, most of the Frankonian civilian and military personnel were saved by a joint evacuation effort consisting of the Septemvirate dynasties Dandale, Garderique, and Merandure, as well as the I Golden Legion.
This event marked the end of the only permanent foreign diplomatic mission to the Heavenly Mandate.
