The way they joined the house of Chaos was very abnormal but that's all in the past. The family has behaved like a normal noble family ever since. What is always current is the Lord of the house of Chaos. Their lord is abnormal and has remained abnormal.
The Lord of Chaos could cross ranks to kill demons of higher ranks. He terrorized the domain of high-rank demons as a mid-rank demon. High-rank demons had to band together to face him and yet, they failed. Then he evolved and became a thorn in the side of his demon lord as a high-rank demon.
The Lord of Chaos is a legend in the 541st plane of the abyss known for his legendary feats and unreal prowess but what topped it all off is that he rose up from being a fledgling to becoming demon king in less than 300 years. That kind of progress is a hundred times too fast. It is very abnormal, to say the least.
For comparison, Beelta the demon lord has been a demon lord for more than 15,000 years, it is still far from the average time of 30,000 years to become a demon king. The Lord of Chaos spent 1% of the average time to become a demon king. Now the lord of the house of Chaos has sent his subordinates to go and kill the demon lord that locked him within the domain of high-rank demons for 200 years.
The progress of their lord was stalled for 200 years and yet he spent a total of 300 years to become a demon king. It is like saying someone spent a total of 300 years to go from the vitality core stage to the Origin god stage. It is also important to know that they spent 200 of those years sleeping. It is that mind-boggling.
One will expect hatred for the one that made them waste 200 of their lives but their lord didn't seem bothered by the wait. They didn't seem bothered enough to kill their jailer themselves despite the fact that it wouldn't take much effort at all. No, the Lord of Chaos sent his subordinates to do that for him.
99 demon dukes entered the demon plane on Aeternus's orders. They came without their army and they came to assassinate the demon lord. There was a similar conflict like this 10,000 years ago that escalated into a war. That war rocked the entire demon plane and left its mark on history. Many thought that there will be a repeat of that war soon. The rise of the Lord of Chaos and his enmity with the demon lord were signs of a possible repeat of history. They were right about the conflict but wrong about the scale.
They expected Aeternus to wage a glorious battle against the tyrant of the plane. He would have demon dukes on his side and the demon lord will have demon nobles with Accumulation on her side. The war was supposed to be epic and earth-shaking. Apparently, it will not be so because the Lord of Chaos considers it all to be beneath him.
So he sent his subordinates. The tyrant of the plane has become their prize and they are to compete for who gets to kill her. He even allowed his subordinates to kill each other too. That's how little he considers the demon lord. For all he cares, it might as well be a free for all with the demon lord as a participant too. After all, anyone can kill anyone. There's no difference between all of them and there are no sides. It is very abnormal. Or it could be a demon king's thing not to care about their subordinates and the boost they get from them.
Baal entered the plane and felt reinvigorated immediately.
"There's nothing like the feeling of home. The Zargoth desert certainly doesn't come close."
He is not calling Zargoth plane a desert because of all the sand and the lack of water. It is a desert because of the lacked of ambient mana. It was suffocating being there. Even as a demon, he could feel the end of the plane approaching. The plane had been stagnant for too long. That is not a good thing in a world where stagnation means death.
The demon invasion might have brought death and destruction to the plane, but it also brought life in the form of mana. That's how it should be. A cycle of life and death in which the best of the best escape that circle to become immortal.
Zernon's peace and order, on the other hand, made the giants of order infect their plane with stagnation and death. The Zargoth plane had no future under his leadership. That has changed now and the demons responsible have returned to their home in the abyss to fulfill the will of their king.
As much as Baal likes being back in an environment with a high concentration of mana and sin energy, he has dangerous work to do so he can't relax. He glanced around and eyed his competition. These competitors of his passed by him as they came out of the portal. He didn't attack them and they didn't attack him because of the truce not to fight at the portal.
He knows for a fact that there are a lot of demon dukes who will like to take his life. It could be because he offended a lot of demons to reach where he is right now. It could also be the innate need of demons to be the strongest and the ones in command. If not for their truce, they will be at each other's throats right now.
Their truce didn't stop them from giving him intense glares full of hatred and promises of violence. They have made their intentions very clear and obvious. They didn't bother to hide it because it will be of no use here. They are already all enemies to each other. Acting nice won't change that and acting harmless will only make them a target. He glared back and made them know that he welcomes every challenger.
