In the last twenty or so years the old hegemony has been overthrown by a junta of generals under a single strongman, while this group didn't outright destroy the old system of various industrial 'kingdoms' they effectively have them under their thumb.
While starting with grand plans to raise the Gali nation to a position of supremacy in the continent's south it has seen nothing but loss or worse.. stalemate in various conflicts with its neighbors mostly toward the goal of taking control of a bluewater port.
The most 'successful' campaign involved the conquest of their neighboring nation to the northwest, the Lebian Barony and while it fell short of reaching the coast and their goal they managed to obtain a vast swath of territory… filled by an angry and uncooperative population.
The gate and its discovery is seen as a salvation and a grant by the gods to give the Gali's a final chance at greatness, this mentality is fanned by a third party fanning the flames in the strong man's mind.
Eventually the above campaign is a failure and overall their armed forces suffer losses from both pouring resources into the unknown (and losing most of them) as well as seeing a general mass uprising in the occupied Lebian territories surrounding the gate artifact. With its loss to the forces from beyond the gate and the havoc they're causing on the Eideon side the Gali military is in a general state of retreat or is cut off and surrounded. Additionally in the east the Dumauri, seeing weakness, have begun incursions seeking to take population and territory straining the Gali forces between the three foes as the Lebian rump throws it's hat in with the newly arrived otherworlders.
