Though the Demons had come as invaders, seeking to take the world for themselves, they were not monsters. Near the end of the Demon War, this became apparent, and even before the end, talks of coexistence had begun. The chevaliers of Albion sought more than just the Demons' destruction, but instead wished to use them as a power source, kickstarting a cruel age of industry. The Haudenosaunee Nations that had claimed much of the New World had a healthy respect for the Demons, but saw coexistence as a far-off dream. In the East, the Nihonese warlord Oda Nobunaga became known as the Demon King precisely because of his willingness to convene with Demons (and Europeans, though there was little distinction between the two in the country at the time.) Nobunaga's unification of the nation cemented Nihon as a bastion of liberty for Demons.

By the start of the Seventeenth Century, the world had been forever changed by hundreds of years of war. However, with their divine generals gone and the gate to the Irkalla closed, both the Demons and humanity had lost their will to fight. Slowly but surely, conflict ground to a halt, and communication began. The truth behind the crisis had been lost, for the most part, but it was known that a fallen Angel (mistakenly thought to be Lucifer, rather than Samael) had brought it about, and the Demons were as much a victim as the kingdoms of Man. In much of the world, an anti-religious sentiment formed as a result. Temples were torn down, or repurposed into homes for the millions of war refugees. Religious groups, like the Kirishitan of Nihon and the Ulimaroan worshipers of the Rainbow Serpents, were persecuted to a shocking degree. Even with these new atrocities, humanity was no longer a dying race. The few Gods who remained governed over their small nations, no longer the masters of Man as a whole.
