The 'entrance' to the core region spanned for five miles. Technically speaking, presently, it was more like a green miasma wall and an energy field which restricted anyone from entering. Not even weapons of mass destruction could break through them, much less normal mutants.
Kiba looked at the miasma wall and energy field which were combinedly acting as a barrier. It was impossible to see within inside though he has an idea of what was present on the other side.
It would be an enormous meteorite.
As per the visuals Claudia provided him, the meteorite barely occupied an area of twenty sq.miles. From a human perspective, this outer area was big, but it wasn't anything compared to the actual dimensions in the meteorite.
"The pieces of Celestial Elsyain Plane are not really meteorites despite their outer appearance," Kiba thought as he recalled BSE79.
