Northern Blade , one Theory Discussed a lot was the Central Heavenly Alliance being behind the Silent Night the whole time. Turns out that the Twin Headed Asura was another contingency of their control, they never accounted for the Northen Heavenly Sect Becoming so powerful to thwart that plan. Also I believe the Night Lords of the Silent Night probably don't realize they are Pawns and only the top leader is aware of such.
MC's old friend's argument against Mu Won is stupid to me , Mu Won has never gone out of his way to ruthlessly slaughter an unsuspecting tribe.
Mu Won's morality makes him feel guilty for the blood shed but he didn't initiate any of it , he is simply surviving at an expert level.
