Would you like Misha to have access to information about it? Sure, and here's his application. Some key points that aren't really brought up in the app:
* Greater Mortals' true existence is a collection of conscious thoughts that have the power to manipulate reality. Earth and all that is mortal is an experiment on the separateness of mind and body, if a life that ends is more precious, what effects do bad deeds have on your soul, etc. etc. blah blah philosophy blah blah. In truth the Greater Mortals are being observed by their benevolent creators, and are they, themselves, being tested on their nature. A test which many of them are failing due to their own self-involvement. And some aliens are playing marbles with their galaxy.
* The original plan with his story was for him to team up with Naumu to track down and stop the serial killer Michael became. So know he has the potential to do something like that in his heart, that some part of him accepted if he met anyone without a soul he would go against his vows to kill them before letting them hurt anyone in spite of his nonviolent nature. This is something he's already confronted in Exsilium.
* Mahdi is a particularly weak example of his kind. He's grown up with people who could literally make music into sights and sounds, or spontaneously materialize items they wanted. What makes him unique is his compassion and drive, and his powers can help others.
* He is entirely traumatized and disillusioned, and is in fact extremely troubled though he maintains an outwardly cheerful disposition. It might seem at odds with his attitude of blind faith and altruism, but in his own way he believes he is 'fighting' the only way he can.
