The First Battle

The First Battle was the first recorded battle in the history of Kierra. This battle, even though it's exact date is lost in history, marked the beginning of the first era and ended the ancient times.
The first battle was located at a village that doesn't exist any more. It is believed it was located the lands now known as the Griffon Empire, somewhere near their main capital, but after five eras any remains of the village has been destroyed and was lost.
The battle began when Demons tried to expand their empire into unknown lands. They came across a village of Humans that was under control of Angels, yet they did not know this. The Demons took a legion and send it there, trying to show their military force as proof they are strong and worthy as their ruler, but once the legion arrived, the angels got word of their plans and had defended the village with their own troops.
Both sides believed they were the absolute race, that nothing could defeat them. They went to fight each other without fear, but after a few hours of fighting, both sides were wiped out and the village was destroyed.
The few survivors on both sides retreated, giving word to their lords about what happened. In the Demon empire, the survivors were executed for running, but their information was been taken in account, resulting in the Demons going to strengthen their borders with troops. In the Angel empire, the survivors were put back into soldering, their stories were not believed. For many years the angels denied the existence of Demons till slowly they lost more and more villages to them, to the Demons.
