The pain of every second reminds this ancestor of the soul-devouring clan about the horror of that Night. It was ravaged, its entire clan was ravaged by one attack.
An attack that brought them to fall and ruins.
An attack that inflicted him with 20 chips cycles of pain. Even lord aphelion would bow down to Night, as his attack only brought 200 mortal years of pain, yet Night attack has brought 20 chaos years of pain to the Ancestor of the soul-devouring creature.
The poor guy with a pride complex has just come out of Its rat hole to conquer a mortal world after deep planning and whatnot but encountered a fucked up person.
It had utilized 20 chaos cycles to collect 100 divine sources just to be sure that there will no problem in capturing a world of mortal, yet here it was, being thrown off Its path to glory by an expert, who has been hiding in the mortal world!
