Tulun Catfolk: Having evolved in the vast jungles and forests of what would later become Enotia, the Catfolk have been present in the northern continents since the Mythic Era. Territorial and quick, the Catfolk did not possess the ability to work together as a larger whole, often spending life in solitary conditions only meeting up to have cubs, or at best forming small family groups and travelling in groups of less than ten. When the Halflings came to Enotia and later the Humans, the Catfolk were first avoided, then hunted, then enslaved by the encroaching invaders. In the course of less than one hundred years the vast majority of the Catfolk populace was domesticated and became second-class citizens in the fledgling Enotian lands. Their history has been one of servitude and rebellion, with many bloody civil uprisings taking place in early Enotian society. In fact it was until the mid-Industrial Era that the Catfolk finally won their independence when the current King declared them equal citizens among the rest of the Enotian populace. Ironically, after so many years of servitude many Catfolk were unable to adjust to a truly “free” life and many turned to crime or became willing servants to others, continuing to perpetuate their reputation as underlings and man-servants. It is a rare thing for a Catfolk to rise to a power of importance or power, and they are often viewed with suspicion and watched closely when they do so, For their part, most Catfolk are in fact very loyal to one another, their ideals and the pursuit of personal freedom.
Place of Origin: Almost all Catfolk come from the Kingdom of Enotia, with a rare few being born further afield in merchant caravans or smaller isolated settlements.
