"Humans truly have no value for their own lives! A meaningless death!" Sonamus scoffed as he stood to his feet.
Sonamus found Gritt to be delusional in the face of death. So what if he took some worthless illusion with him? The words he spoke were a bunch of nonsense. Bahamut had already slain the other human brat; therefore, Sonamus knew that no one left in the dreamworld had the power to threaten him.
Even if that woman somehow made it to the palace, it would be too late to do anything as the dreamworld was less than a minute away from destruction.
Once the dreamworld was broken, Sonamus planned to keep his promise and exterminate every human in a 100km radius. If that were not enough to quench his rage, then he would increase it to 200km. After all, as a Night Lord of the Antumbra, if he did not retaliate, wouldn't those humans begin to forget their place?
