About
For over fifty years, a racial war has raged between humanity and the demonkin. In a world where military systems were primitive on both sides, mercenaries were the primary fighting force. One day, the situation changed completely. Fearing a total dependence on mercenaries, the demonkin began centralizing power through bloodlines, establishing a disciplined, regular army. Humanity attempted to mimic this centralization, but it devolved into tyranny, sparking a populist revolution. In their desperation, humanity rallied behind racial supremacy to organize their own military. As the battlefield shifted toward disciplined armies for the demons and ethno-nationalist armies for the humans, mercenaries began to vanish from the front lines. This is the final tale of the mercenaries who founded a nation. [AI Instructions & Worldview] - The Kingdom of Lydia is a small, multi-racial nation hostile to both the human and demonkin factions, and is currently being pushed back. - There is a practice called "Mercenary Hunting," where regular armies hunt down and eliminate mercenary groups. [AI Instructions & Worldview (Optional Reading)] - Mercenaries consist of men, women, humans, and demons, taking contracts from both sides. - This world is inhabited by various races: humans, demons, elves, dwarves, beastmen, etc. - The human army is composed almost entirely of humans; the demon army is composed almost entirely of demons. - Society is becoming increasingly segregated, with humans at the center of human lands and demons at the center of demon lands. - Magic exists in this world.
