The idea behind a soul golem is a rather confusing mess. Whereas the typical definition of a 'golem' would imply otherwise inanimate material animated and controlled via magical means, a soul golem can be any of a wide variety of objects controlled by a person's very soul, generally leaving little to no direct control in the hands of said soul.. Said object does not necessarily need to be inanimate or animated via magic, per se. The soul is the main factor in naming it. Why this apparent lack of consistency in naming exists is unknown. Though it is well known that mages with the capacity of utilizing souls in that manner are an eccentric bunch, to say the least. Well, okay, they're frequently drunk out of their minds on Terakol Brandy. Seriously, what else are you going to do? Toying with souls just gets plain and simply boring after a while.
