Nephilim

Nephilim, also known as giants, are an esoteric race of creatures indigenous to Agartha, a purported utopian realm located on the underside of the earth's crust. Very little is known about them as a whole, as they are a very secretive species, but historians and poets from ancient times have described them as a much larger, physically-powerful, and extremely-intelligent species that very similarly resemble humans, only with longer faces, wider hands, and extremely long limbs.
