The Arbor has never maintained a standing military force, instead relying on levies in times of war. For a long time, the sole exception to this rule were respective city guards of Norianne and Thorne, but public outcry for increased security following the destruction of the Capital Lands led to the formation of the Rangers of Rollen. Contrary to the City Guard, these Rangers were tasked with maintaining security in the expansive forests that cover most of The Arbor, and along the duchy’s roads.
