The Joint and Indivisible Realm of Mestonia, also known as Mestonia or the Mestonia Park is a semi-independent country in the continent of Delgamia. Formerly part of the Gronkian colony of Novoyoakes, the territory was occupied by the member states of the Melanian Sea Treaty Organization following the Treaty of Puerto Bravo, in July 299. Subsequently, the sparsely-populated country was organized as a natural preserve with limited economical development.
