The Hand organisation began centuries ago in feudal Japan. Seeking autonomy from the oppressive class system of the time, a few citizens fled into the mountainous regions and began developing the stealthy martial art of ninjitsu. Over the centuries they refined this art in secluded camps, training new members from birth. With the changing of their society in modern times, the Hand have changed their goals towards worship of a demonic entity called the Beast.
The Hand have demonstrated powerful magical abilities in conjunction with their martial arts prowess. Able to resurrect the dead as their servants, the Hand have a nearly inexhaustible supply of foot soldiers in the pursuit of their goals.
