Osho

Osho was a ronin bushi in the 12th century.

Hired Killer
Osho was born the illegitimate son of a geisha and a clan samurai who left him a blade and some money. He had been a hired killer for most of his adult life.

The Lair
Osho was discovered in the Twilight Mountains killing one of his hired targets, a bandit. He presented himself as a wave-man to the samurai, members of the supposedly extinct Boar Clan. Osho was brought to the Lair, a remote valley isolated from the Emerald Empire since the destruction of their clan in the early 6th century. Osho was told he would never be allowed to leave the plateau, and he accepted his fate, dutifully slaughtering the enemies of the Boar Clan until a better offer was to present itself.
