Goblins are a common and often fairly weak humanoid monster found in the popular Dungeons & Dragons universe - unlike many other realities Goblins are not considered smaller "cousins" of the orcs in this setting and stand as a species in their own right: though they are considered somewhat related to beings such as Hobgoblins and Bugbears, which make up the goblinoid family. Goblins are based on the mischievious and often ugly monster from folklore, who were believed to cause trouble for people in a manner similar to modern accounts of poltergeists or "unclean spirits".
