What I am trying to convey is that (now bear with me here I'm working on a novel)  cosmos is divided into twelve sectors, beyond which is empty space.

Ultimately, I need the sectors to be barely visible while encompassing a universe of galaxies and star systems.

In the center of this cosmos is a central sun around which all this revolves, and like a galaxy, the mass of it extends in an eliptical, horizontal orbit around the central sun. The sun, in its brilliance, needs to blaze through the stars and the slices as it is more brilliant and bright than all that surrounds it.

So, the segmentation shows the division of the material cosmos, and within it are the mass of star systems and galaxies. And at the core of it all is the central sun.

The walls between the slices designate the division of sectors, but they don't need to be so opaque, but do need to be seen.

Appreciate the help seachnasaigh.
