When the universe was created, sections or portions of the over arching physical body had openings or tears that leaked pure pockets of energy that came directly from the mind and soul of the "father". This energy later dubbed Aether, if manipulated was capable of bending reality or the physics of a given area to what the user desired. This energy was leaking out all over the universe, and on planets whole sections would connect with each other and create a grid that would bleed over entire areas. The grid system would later be dubbed ley lines by modern magi.
Now around the areas where these ley lines exist, the aether would slowly affect lifeforms that reside there and as a result the environment would indirectly help birth celestial like beings whose composition was designed off of man and the nearby environment instead of the "father". These beings are later dubbed Deities, or the Gods of Old. When these being began to appear the residing primitives would flock to these beings of immense power and would begin to worship them as much as they did the "father". This would shape each ones own personalty and ideologies base around whoever worshiped them and as a result worlds all over were ruled by the Deities that varied in personality and were short tempered.
"Father" wasn't to pleased with they're behavior at first and thought they tended to do more harm then anything else, he still thought of them as his children despite having little to do with their creation and only stepped in to intervene when he thought things got out of hand.
