Formerly known as the Fox Clan, the Kitsune joined the Mantis Clan decades after the other families founded it, and only then because the Fox were on the brink of annihilation and the Yoritomo could save them, with the only price being an oath of fealty. The Kitsune are a simple, quiet people who prefer to commune with the spirits of nature in the forest rather than travel across the Empire on formal business.
Of the eight Kami who competed within the first Celestial Tournament, seven went forth to honor their Emperor by creating Great Clans to serve him. Since that time, one additional Great Clan has been given leave ny the Emperor to serve him in the the same manner as the others, and one other self-titled "clan" has claimed the title but never been recognized.
In theory, the Great Clans command only what power is granted to them by he Emperor. This consists of the power to fulfill their specific duties without interfering with the duties of other clans, and to govern over the Emperor's lands bestowed to them in his name. In reality, of course, each clan commands considerable military, economic, and political power, enough to overthrow the Empire, and only the power of the other clans keeps them in check - that and the fact that no honorable Clan Champion would ever consider such a blasphemous and disgraceful act.
Although all Great Clans are ultimately loyal to the Emperor, they can and do have radically different outlooks on virtually every aspect of life, and conflicts between them are common. Most Emperors have historically chosen not to interfere with inter-clan wars because they permit the clans to vent their hostility honorably. After all, denying a massive force of noble warriors the right to pursue satisfaction in what they consider a matter of honor is generally a poor idea.
The Mantis Clan is adaptable and unpredictable, and many find the Mantis to be much like the seas on which they travel from their island holdings to the mainland Empire. The Mantis were not born a Great Clan, but seized the position during one of the greatest conflicts in history, the Clan War. Comprised of families formed from different Minor Clans, the Mantis are perhaps the most diverse and individualistic of the Great Clans.
Before the formation of the Mantis as a Great Clan, the Moshi were the Centipede Clan. An extremely devout and matriarchal people, the Moshi devoted themselves to the worship of the Sun for centuries, and find their active role among the other families of the Mantis mildly uncomfortable. Still, the family has sworn an oath to the Yoritomo and refuses to break it, no matter how much their duties conflict with their philosophies.
Formerly known as the Wasp Clan, the Tsuruchi are without question the greatest archers in the Empire, and have focused the majority of their efforts toward maintaining that level of skill. Generally perceptive and highly athletic, the Tsuruchi excel as warriors and magistrates.
The Yoritomo Family: +1Stamina [CR]
The lords of the Mantis are descended from the Crab, and are equally hardy in their own way. They are the unquestioned masters of the seas, having dwelled on the Islands of Silk and Spice for the entirety of their existence. The Yoritomo are a hardy, industrious people ever eager to prove themselves against the other Great Clans.
