Universal agreements are contracts made with Kinetic Energy involving themselves or others.
Universal Agreements are contracts created via kinetic energy that a manipulator of said kinetic energy can make for themselves or for others. The contracts created must follow the rules of the agreement or the agreement is null and consequences will be inflicted on the party that broke the agreement.
