Then Helios went to the divine plane and confirmed that he got stronger instead of suppressed. He used his power to execute the plan to make Aeternus a demon king. It all seemed ingenious at the time. They planned and schemed and they thought they were the mastermind while everyone else was puppets moving according to their will. Now they feel like fools. Apparently, the real mastermind is the unknown Celestial god of Fate.
The tree father consoled them. "We got most of what we wanted. I have faith. Aeternus has become a demon king and has enough godhood and divinity to empower his house. And Helios has the Authority of order and the sun that he wanted for his experiments. We just don't have the Authority of the Celestial Supreme so that we can gain full control of the plane and advance the plan for the infinite energy production that Soverick planned."
The others agreed reluctantly and decided to move on. All three of them had various objectives that they wished to get from the Zargoth plane and they achieved most of them.
Aeternus was being hounded by the Demon lord. Waging a war on her when he is obviously outclassed would have been stupid. He needed Accumulation to be a match for her and there are 8 other demon nobles with divine rank Accumulation who are his enemies too. His demon dukes fall short of being capable of facing these threats. They need divinity to upgrade their stats to the half-divine rank and for increasing their Accumulation too.
All of his problems could be solved by divinity from gods which cannot be gotten in the abyss. Zargoth plane had everything he wanted. It had gods and it didn't have a strong populace. But trying to leave the abyss meant getting ambushed by the demon lord. So he needed help.
The tree father on the other end needed faith from believers. It is not a simple thing to acquire faith in the Zargoth plane. Zernon had total control of the plane and will destroy new churches and religions. Zernon would have initiated total war on the tree father if he knew that the tree father had the power of a Celestial. So the tree father had to stay hidden and needed help.
Helios on the other hand could have lived an easy life despite being born a demigod or he might have died in the womb. Fortunately or unfortunately for him, Stelios laid his eyes on him and marked him. He was being constantly monitored and his movement was restricted. He also needed divine power in large quantities for runes. His objective to get to the bottom of Authority by analyzing runes would have been hampered severely without divine power. So he needed help.
The Authority of the Celestial Supreme is something that they decided to get once their plane began showing great success. They decided to take control of the entire plane so that they will have a base other than the Virut plane for the era of conquest. Taking total control of the plane will also make it easy for them to ensure that the Tree father will be the only god in the plane.
Now they have everything they needed and they should be happy. But the fact that they can't get what they want is making them sour. Not just them, the entirety of Legion is incensed but there's nothing they can do short of bringing Legion-1 in. The suppression of the realm on Origin gods might make that move useless too so they decided not to bother with that.
The three of them don't have the strength to get what they want now, but that doesn't mean they are giving up. The entirety of Legion will not forget the humiliation and will get back at Zerkon. Revenge is just one of their motivations for going after the god of fate. Legion also finds Zerkon's immunity intriguing and is interested in getting to the bottom of it.
Aeternus's POV
Aeternus's main body is still in front of the fortress. He was standing there when the GodSlayer attacked him. He is still standing there now but that's because he can't move his body. Replicating that attack took more out of him than he expected and he expected pretty bad consequences before the amount of Authority was increased from 3 to 5.
His crystal body cracked all over to reveal the golden bones beneath. Black fumes leaked out from the cracks and obscured his figure like they used to do. The golden light in his eyes dimmed a little. His soul was terribly weakened by the intensive exercise he went through. He remained standing and directed his avatars in the divine plane to do his bidding.
Fortunately, is a demon king and he is not a normal one. Healing as always been easy for him. It took some time but he healed. He became able to move but he stayed where he was and practiced. His subordinates arrived one by one over the period of his wait. The fortress was also completed and the channel to the abyss altar was fully connected. It was then that he called his subordinates over to reward them and give them their next mission.
All 99 dukes surrounded him and awaited his judgment.
He said to them. "All the churches of the gods have been destroyed and all the gods of the plane have been killed except the Celestials. Our mission has been completed and it is time for you to be rewarded."
The demon dukes did good work. It was easy work but they did it well. They wiped out the churches and the priests. Some remnants escaped but those remnants have become inconsequential with the death of all the gods of the pantheon.
The legions of demons roamed all over the plane and pushed the giants of Order toward the kingdom of life. It gives the tree father control of the largest portion of faith in the plane and will ensure that he will be without competition for a very long time.
