In this universe, we are at least a little more than the Middle Ages. There are hybrids and demons. All start with animals and humans. It all started when humans wanted to experiment to be able to create a human half animal. The experiments were successful and that's where the hybrids come from, humans with characteristics of any animal, after generations, there is a bit of everything. With all these experiments, the hybrids were afraid of humans.with a little experience they managed to create a hybrid but with powers,so a demon. It explains why some demons have physical characteristics of animals because they descend from hybrid.The demons were overpowering, they had the intelligence of humans, the agility of hybrids and their own powers given and changed from generation to generation.In fact, all these races were created by humans because of scientific experimentation until creating humans who are half animal = hybrids, the hybrids were exploited by humans and then they finally all decided to flee, except that obviously the humans did not agree.They managed to capture other hybrids and with a little. Knowing that these creatures were free scared them. But from generation to generation, the older generations of humans told the news that these were only legends.But actually no. The demons had just created their own camp and a civilization. And the hybrids too, the hybrids hid from everyone. While the demons had a grudge against humans, no one believed in hybrids anymore because it was so rare to see them, but apparently they had a village, but that was never proven.And the humans want to find the hybrids and demons to continue their experiments, but all hide from them. Not risking their lives.
