It wasn't until a booming sound, making the land tremble ever so slightly, reverberated in their ears did the knights wake up from their musings. The individuals in the group were certain that the sound came from inside the pillar, so they were not worried about the citizens' safety. But only for the time being.
First, they had to process what the Demon Noble had just said. Not a single one of its words were able to make its way into the knights' reasoning.
Demon Nobles? Some humans had already witnessed the destruction that a Demon Noble could do. Once in a while, demons visited this world to wreak havoc. Having said that, there were only a handful of humans who lived to tell the tale of their visits.
Angels? It's a given that in the Seraphiel Empire, solely the individuals who had seen the presence of an Angel were the Rounds and the Emperor.
