Magion

For centuries, the word magion was one of many terms used to refer to magical beings. The earliest written record of the word is in a fragment of a damaged grimoire, dated to the 9th century and believed to belong to the Hungarian Vrac̆ branch. The phrasing suggests that the term already existed, but seems to have had a slightly different use, which is now lost to us.
The term gained popularity in the late 18th century, and became the preferred umbrella term for magical lifeforms after Göran Elias Pederssen (1805 - 1890) used it to coin the term 'magiontology' in 1853.
