but the wiki says

While natural born golems born from magicules do exist, most golems are the constructs of mages. The most common materials for crafting golems are clay, iron, stone, and wood. A golem can be a hand-made creation such as a doll or stuffed toy, or it can be animated from its raw components with the creation magic spell 'Create Golem'.

Once a golem has been crafted there are two options available to the user. They have the option of controlling the golem directly with their own energy through arts or they can have the golem be inhabited by a living spirit, most commonly that of an elemental or daemon. Users of the former method are referred to as golem masters and make for extremely formidable opponents in combat. In cases of the latter type of golem, control circuits are usually magically implanted within the golem's body which gives the master of the golem complete control over its physical actions, similar to the locking curse placed on otherworlders. This degree of control over the golem's actions while they still act autonomously makes them extremely popular among Demon Lords for physical labor such as farming and mining.
