As the first born son of Cronus the world was his birthright and even though it takes some time eventually every person will become one of his subjects.
I mean...lightning guy gets the sky....water guy gets the sea....undead guy gets the underworld...seems like they were predestined and the lots didn't matter lol. imagine if the water god ruled the sky, would it be raining all the gosh darn time? and if Zeus ruled the ocean would lightning come from the sea? lol
At the end of the day, OUR LORD JESUS CHRIST THE SAVIOUR OF THE WHOLE WORLD REMAINS THE ONLY TRUE GOD, IF YOU DOESN'T HAVE CHRIST JESUS INTO YOUR LIFE YOU SHALL PERISH IN HELL FIRE.
