Of course, in the very beginning, it was not a true alliance organization, and its name was quite different from today.
At that time, its accurate designation was actually—the Pan-Southern Cooperation Alliance, merely a cross-Southern Region intelligence sharing system; its primary purpose was to prevent another invasion by the Empire and to self-check the rampant infiltration of cultists into various guilds at that time.
However, as time passed, the cooperation between natives and Invokers, and among Invokers themselves, became increasingly deep, and the functions of the organization became more diversified, gradually forming a large guild union spanning the Emerald Forest, Fanric, Dyce, and the Central Mountains regions.
