What is a Goblin?
A Goblin (alt. spellings: gobbelin, gobblin, goblyn, gobling, gobelin) is a mischievous, and usually very unpleasant, vengeful, and greedy creature whose primary purpose is to cause trouble to humankind; this is the most common type according to European folklore. There is a smaller population of Goblins, however, that possess a kinder, or more neutral temperament. Regardless of the type, though, all Goblins are rumored to hold various kinds of special abilities, often magical in nature. Some Goblins possess morefairy-like powers, similar to those of a witch or warlock; other types of Goblin have more demonic abilities, only using their magic to do harm.
