Quoted By:
What Julian always struggled with was that, once he had escaped from the Children of Fas, what was he supposed to do with his life? In the Fassian faith, it is believed that your purpose in life (therein Fate) is supposed to be something to make you happy for the rest of your life.
Julian's 'Chaos Period' mainly occurred because he never found that something, and had gravely hurt himself (and others) trying to.
This eventually ended because of Julian split the ideology by introducing a more nihilistic sect (Berkerian) and making his life purpose witnessing Fate in action.
