"A-agreement?" Principal Mar stammered.
In Spike's hand was a written agreement. He wasn't that stupid to mindlessly take over this city. He knew that even if they succeeded in occupying the city— their effort would be wasted because of one of the laws in the World Agreement.
Enforcers enforcing the agreement are sure to take action when this matter reaches them. If that would be going to happen, then occupying the city was a dumb choice.
It was in the agreement that when the foreign-led city is occupied by enemies, the administrator who facilitates the law will send strong forces to annihilate the invaders and restore leadership to the original administrator of the city.
In exchange for their protection, the foreign-led cities were paying taxes to the organization. It was a give-and-take relationship between the cities and the organization.
