Military action
According to historical notes, as early as 15 AD to as late as 32 AD, the first large-scale invasions and conquests took place. When the Dormæeus, Chosen of Eos, were sent south of the Heartstones to defeat the southern and western tribes, which at the time consisted mainly of orcs, giants, and other primal beasts.
This would then lead to the formation of the Riverlands, around the Frailmark, later one of Zenith's most contested and warriddled regions.
In large parts, the conquests were succesful, and the Dormæeus was rewarded with kingdoms of their own, forming two new nations under the Ellisiat banner: Versille and Virmia.
