Nothing special just a sphere within a sphere, no hidden knowledge or secret here.
For me this is the purpose of this spheres, to produce fire.
"The name pyrite is derived from the Greek πυρίτης (puritēs), "of fire" or "in fire", in turn from πύρ (pur), "fire". In
ancient Roman times, this name was applied to several types of stone that would create sparks when struck against steel"
"Pyrite enjoyed brief popularity in the 16th and 17th centuries as a source of ignition in early firearms, most notably the wheellock, where the cock
held a lump of pyrite against a circular file to strike the sparks needed to fire the gun."
