Yotsu family

The Yotsu family are a ronin family who were given their name by the Emperor Hantei XXXVIII in 1111.

Founding
In 1111, after the caravan of the second wife of Hantei XXXVIII, Hichiahime, was attacked and Hochiahime and the son of the Emperor of Rokugan, Hantei Sotorii, were taken by a bloodspeaker cult to be sacrificed to fulfill an ancient prophecy.

The mountain-dwelling Yotsu crept into the camp and knowing he cannot defeat the entire cult asks the Empress for permission to die in her name. She forbids it, telling the ronin to save Sotorii and tell the Emperor to mourne her unborn child.

As he cannot take the heir without it alerting the cult, Yotsu replaces him withhis own son. Weeks later Sotorii is reunited with the Emperor and as a reward for Yotsu's sacrifice he is named Yotsu Yatoshin, after the Emperor's father, and given a small fiefdom in the Mountians of Regret and rule over a district in Otosan Uchi.

Sword of Yotsu
In 1116, Yotsu Yatoshin begins swearing ronin outside his family to the Yotsu name, training them in the techniques he had learned while living deep in the mountains. And so the Sword of Yotsu otokodate was formed.
