Golem
In Jewish folklore, a golem (/ˈɡoʊləm/ GOH-ləm; Hebrew: גולם) is an animated anthropomorphic being that is created entirely from inanimate matter (usually clay or mud). The word was used to mean an amorphous, unformed material in Psalms and medieval writing. The most famous golem narrative involves Judah Loew ben Bezalel, the late-16th-century rabbi of Prague. This closely mimics reality, whereupon magical casters infuse their essence or that of a spirit into matter of some kind, forming an anthropomorphic object. Golems can be used for good or ill and have little or no mind of their own, relying on their creator for guidance. In the case of your average golem, if their creator is slain, the golem will revert back into the materials from which it was constructed. However, demonic golems, the kind bound to the will of a demon lord or a dark god, needs no input from an outside master, obeying the direct will and commands of the evil being whose spirit animates it from the Outer Darkness.
