Okay lets look at this in simple terms Yairi. What is a treaty?
An agreement between the governments of two cities. End of story. Since three
of Mercinae's existing four barons have now publically posted opposition
to said treaty (with the fourth yet to make an opinion known), any treaty is
null and void.
Yes you may have had a treaty signing witnessed, but without the support
of a government the paper is worthless!
