Rat

an underground society of people who worship their rat god 'Rattius'. They call themselves the rats and have been at war with the mouse clan. For centuries the rat cult has preformed many sacrificial events for their god and continue through to this day. The cult was founded in 15B.C. by Rathula the Third and every year there is an annual crowning of the ruler.
