Golem
A mystical fantasy creature that has been around since ancient Hebrew times is the Golem. This 'robot', so to speak, is made of large amounts of clay formed into the rough shape of the human form. The Golem can vary in size depending on how much clay is used, but typically range from average human size to two times a large.
The Golem is essentially a primitive robot, but insead of metal and electricity, they're made from clay and powered my magic. They are created by ancient mystics to perform a certain task, from hard labor to disposal of one's enemies.
The Golem has always been a symbol of protection, either to protect an area from outsiders or to protect a group of people from their enemies. These creatures can be made from soft or hard clay, giving them different strengths and weaknesses depending on the form they're in.
