It didn't take long for the dozen or so Overlords to sign the vassal contracts.
Apart from Karman and Wilton, who had Silver-level territories, the rest had Bronze-level territories. Consequently, Charles's vassal territory expanded from 46 kilometers to 115 kilometers, and his vassal population grew from 20,000 to 40,000.
These were all temporary subordinate forces, they could leave at any time, so strictly speaking, they weren't part of Charles's core power.
There were no limitations to this, if Charles had the strength, he could theoretically sign contracts with 10,000 subordinate forces.
The embryonic forms of major powers and nations often evolved from this model.
