1000years ago.
Other than humans, there lived creatures like monster, beasts and lots. Yea... reptiles to be specific. Reptiles _snake reptiles that are in human form and are capable to transform to their snake self.
Both creatures lived in their own separate clans. They lived peacefully their separate lives having no problems with each other but then something happened.
The leader of the humans was greedy, wanted more than just their land, he wanted power and supremacy over the snakes clan. There was a war, in which all snakes were killed but only one escaped. One which was currently pregnant, she escaped far away and soon gave birth to her child. Whereas the snake land was claimed by the humans.
Years went by and the humans developed. They built companies, banks, stores, schools and lots. The human land became a fine beautiful urban settlement.
