Golems are artificial creatures created by magic. They are made from different materials, and are usually physically potent. Golems usually are animated with a spirit or elemental that has been bound or infused into the golem. Usually the bindings are permanent, and the golem is under the control of its master.
Most golems are not sentient, but a few exceptional ones do gain awareness. Golems are usually humanoid in form, though some can resemble other creatures.
