Djinn

Historical Background
The term djinn (also "jinn") refers to a race of supernatural creatures or spirits in both pre-Islamic Middle Eastern folklore and in Islamic Culture itself, singular djinni (or "jinn," "djinni," English "genie). Djinn are creatures of free will, said to be made of "smokeless fire" (the literal translation being “subtle fire”, i.e., a fire which does not give itself away through smoke), and live in communities much like humans. The word itself literally means anything which has the connotation of concealment, invisibility, seclusion, and remoteness.

The word "ignis" is latin for "fire." Taken literally, Ignis Djinn might mean "subtle fire" or "hidden fire," linking with the supposed building blocks of the djinn.
