Gremlins are spirits of tools and machinery. They are thought to be responsible for mishaps and breakdowns with tools and equipment. Each house has a Gremlin which entered the house as an occupant of an household appliance. Originally Gremlins were friendly towards other beings and helped engineers and inventors build things but when these people took all the credit the Gremlins were insulted and from that point on they work against those beings.
