Enochian is the native language of Nephilim and Ka’im. Its “spoken” form is actually silent and relies on the manipulation and display of the elemental fields. For this reason, the language can only be spoken between individuals using Ka-Vision. This allows communication through physical barriers but can be intercepted by anyone who can use Ka-Vision and understand the language.
There is a written form of Enochian as well. It looks like a more complicated form of Cuneiform. The complexity of the language is very subtle, and virtually impossible for someone not schooled in the language to translate. For this reason, Nephilm often record the esoteric writings in Enochian.
