Impy/Origin

Origin
Impy is an imp. An imp is a mythological being similar to a fairy or demon, frequently described in folklore and superstition. The word may perhaps derive from the term ympe, used to denote a young grafted tree. Imps are rather mischievious rather than evil or harmful. Some see them as attendents of gods. They are shown as small and unattractive creatures, and are wild and uncontrollable much like a fairy. They search for attention, so they pull pranks to gather attentions from humans.
