Hexagram

[Onbael_]

I thought about this:

Satanas + Baalzebul + Astarte
(Female aspect (?))

Satanas + Baalzebul + Azazel
(Male aspect (?))

...or also this:

Marbas + Orobas

6 letters outside and 6 on the inside.

 

[Onbael_]

Or maybe an octahedron, drawable as an hexagon in 2d.

4 elements, and the upper center, light.
At the lower one, darkness.

Just theories about the union of 6 Gods.
