WARNING - LORE BREAK RESPONSE
So,
I cannot speak for the intricate details (or lack thereof) concerning the lore for MGE as it is written.
But I can imagine that a 'hero' of The Order would be blessed due to the example they set forth.....especially given the older history of MGE as a whole.
The qualities a hero would / should display would be formidable. In terms of battle prowess and a certain selfless and benevolent pattern of behavior to the population at large.
In short; all the qualities and characteristics the stories and imagery the word ''hero'' would bring to mind.
For if the CG would only bless bloodthirsty killers who were ruthless, merciless, and were, more-or-less despicable entities within The Order.....why call them heroes then?
That would be more akin to a warlord.
But more than that- I imagine if "Heroes" were only known for their prowess in killing the enemy, the belief foundation in which The Order survives off of, would collapse.
For it would allow the general populace to know the CG didn't care about them, right along with the higher echelon of governance, and then how quickly would the power structure fall apart?
From what I have read, the top hero the CG attempted to use to unseat the current demon lord (CDL) not only retained his great power, but it was magnified once he joined up with the CDL
It would be my guess that once a hero is blessed, they are always blessed.
They are blessed due to the deeds and service and character that is a part of them.
You can't just discard that on a whim, nor could you a blessing from what should be a benevolent figurehead to humanity.
A CG blessing a hero is, in my opinion a gamble. A risk.
Will the hero remain loyal to the CG once they realize they are slaughtering mamono who don't want to kill?
Or will the 'good' in their heart make them lay down their arms and turn their back on killing of innocents?
It is a very interesting situation that has been left behind from what it was, to its new application in the world of MGE
The blessing of a hero, was once used in defense of the people against monsters that were blood thirsty and mindless in the pursuit of killing humanity.
The heroes then must have been so very sure and confident in their purpose and appointed role.
Now,
I can only imagine the conflict a ''good'' hero would have in the face of harming mamono.
Blessing?
Now, I am not so sure anymore.
Ever your Servant-
