Since the beginning of time,demons have always suppressed humans, killing and slaughtering them just for the joy of it. There was no real motive. The human race was reducing drastically and if this continued, humans would become extinct.
The humans began to retaliate, fighting the demons, but there was no visible change, demons were just too strong and too many.
Augustus, the emperor of the Hastoria empire, came up with a way to keep the demons at bay. They would be attacked with holy scriptures, this method was working and hope filled the hearts of the hearts of the humans. They could finally get rid of them , but that wasn't the only plan Augustus had. He wanted to seal them forever, he needed the blood of seven special humans, these humans were gifted with magic, and they were very few. He searched across the whole land and was able to coerce some certain people to give their life up for the good cause. The ritual took place and was successful, the demons were trapped in the valley of Gargamura and they couldn't suppress the humans anymore.
Overtime, People began to forget about the demons until all memories of their existence became a legend that seemed to be too unreal.
Thousands of years passed until one day a man was unfortunate enough to stumble upon the valley of Gargamura. In his foolishness, he cast a spell because he sensed something was bound, he broke the spell after many months of trying, to his horror, a demon with elongated fangs welcomed him.Of course, he faced immediate death but the demons had escaped and they weren't going to give any human the chance to chain them again, humans were inferior to them and they were going to face the consequences of their actions. The demons had escaped and the world was plunged into terror again.
