Interesting power dynamic. I had thought the Argon Holy Empire would put much more of a fight considering we saw how their knights wiped out the Orc army with ease. Mind you, these were Orcs which even Dark's personally trained troops couldn't win without the use of titans. Judging from what was explained, the Argon Holy Empire hasn't had a war in a long time, which caused them to be lax in the Titan arms race and ended up over relying on their knight's Aura Swords to do most of their heavy lifting. I guess this is what you call a paradigm shift in terms of warfare? Like comparing tanks to an assault rifle fight. Both have their respective roles on the battlefield, but I am a bit disappointed how easily the Argon Holy Knight's were defeated.
Now, I have to wonder what exactly Holy Power is. Seems like a different energy source compared this world's idea of mana or Dark's Qi.
