A force that lies within tradesman working under the name smith. Has historical meaning and is also shrouded in secrecy and mysticism. Once a part of the clan the true meaning and what it is to be a smithy are slowly learned, once attained it is highly regarded and the one that possesses it will fight relentlessly to hold the name in high regards. People see a man running scared for his job but in esscence this is a smithy held by greater force propelling him to put his own belief system aside for the regard of the clandestine ways of a true smithy. It's taken close to one hundred years to develop this surname, and a many great men have laid the path for future generations.
