Ainsley and the Téssera Alliance really did plan to create such an overlord for each country.
Each country could only have a dozen forces that had the reseller license. Others could only buy the stones for their private uses.
The Téssera Alliance also didn't accept orders from families outside of their business circle, which means other families had to find these 'overlords' if they wanted to buy stones.
Thus, whoever could become the overlords in their country would be a fearsome existence in their prospective country!
This is Jake's idea to open a connection in various countries with Ainsley and Pandora Island as the center.
This way, the baby didn't have to go to various human countries to establish her guild and could rely on the local overlords to help her.
These overlords included various military families, noble or merchant families, organizations, guilds, clubs, and so on.
