Cause
The Nhaga are cold-blooded reptilian beings who depend on warm, forested environments. As their population grew, they needed more forest territory for hunting. The northern peoples (Humans, Rekon, Tokkebi) needed open farmland for grain cultivation. These two needs were fundamentally incompatible, and the conflict was territorial at its core.
The Nhaga initiated a campaign of expansion northward approximately 1,500 years before the events of the novels. This was not a single battle but a prolonged, multi-front war that reshaped the continent.
The northern response
Before the war, the northern races were fragmented. Humans, Rekon, and Tokkebi had their own territories and their own problems with each other. The Nhaga advance forced cooperation. The Hero King, a Rekon warrior of extraordinary ability, emerged as the figure who united these fractured factions into a fighting force capable of resisting the Nhaga.
This unification is what led to the founding of the Arajit Kingdom. The kingdom was not planned; it grew out of the alliances forged during wartime.
The Line of Limit
The war eventually reached a geographic stalemate. The Nhaga's cold-blooded physiology meant they could not survive in the colder northern climates. A natural boundary formed, known as the Line of Limit. South of this line, the Nhaga planted dense forests, creating the labyrinthine region called Kiboren (also romanized as Koboren). North of it, the land belonged to the Arajit Kingdom.
Under King Geugyeon, the 21st monarch, the Nhaga were definitively pushed south of the Line of Limit. But the boundary was always contested, and small-scale border conflicts continued for centuries.
In Project Windless
The game is set during this war. Players experience the early stages of the conflict as the Hero King, fighting in large-scale battles powered by Mass Technology and forging the alliances that will eventually become the Arajit Kingdom. The war provides both the narrative framework and the gameplay context for the continent-spanning conflict.
