Military action
The Marcisian Empire begins their occupation of the island country to the north by invading the elven country, Elgranar, which is later known as Western Anestor.
Thirteen legions traveled across the sea from Marceaux to Elgranar and began their occupation and invasion of the elven country. Elgranar was completely unprepared for the invasion. They'd been safe up until then, because the ocean surrounding it was rather dangerous. No ships could safely travel across the open water there until that point, but Marcisians invented a better way to build ships.
