Hades

Hades is a God of the Underworld.  

There's this famous story about in-utero Hades and his stillborn twin-sister Glauke.  The lesson to learn here is one is about the disparity between men and women when isolated and separated from a collective.  Men are biologically built to survive in those conditions naturally where women need that connection.  In twin fetuses, if one is twin is biologically deficient and doesn't have what they need to survive the stronger viable twin will deprive or put the deficient twin out of their misery. 

All you need is the truth...

I think the collective is the moon.

"Birth is when the soul enters the body..."
