Through Eve's sacrifice, the world ushered in a brief period of peace. During this time, by understanding the power of the Knights of the Celestial Realm, the swordsman Orram gradually grew into the Celestial Vault Icon Knight. Orram, who is no longer a teenager, has more indifference on his face after experiencing life and death.

Imduq, who guards the dragon, also grew during this time, perhaps due to the influence of Oram's power, and the guardian dragon grew into a being called the Icon Knight of the Stars. The combat strength has not been greatly improved, and the body has become very resistant to beating, which can only be said to be worthy of being a guardian dragon.
After the death of his sister Eve, his brother Ningirsu left the Forest of Stars. Although Olam and the Guardian Dragon were not at ease that Ning Gilsu was alone, the Machine Worm did not know why it had suddenly awakened again, and although there was no sign of a violent escape, it was still a threat to the inhabitants of the Forest. Instead of the deceased Eve, Orram and the Guardian Dragon choose to stay in the Forest of Stars to guard the forest.
In contact with the Monster Worm, Orram, who inherited the power of the Knights of the Machine Realm, began to gradually discover that he also had the ability to control the Machine Monster Worm. After all, a long time ago, the Monster Worm was a puppet controlled by 7 Knights of the Machine Realm. By making good use of this ability, Orram guided some of the Monster Worms out of the human area of activity and transformed some of them into his own Iconoclas.
After completely transforming the Monster Worm into an Icon Knight, Orram began to gain access to the Monster Worm Core. By reading the data inside the Monster Worm, Orram learned that there was information about the disaster caused by the Holy Relic in ancient times, and also understood that the Monster Worm was actually a security measure to prevent the Star Relic from being activated again. This reminded Oram that if it hadn't been for the goblin Liz activating the Star Cup, maybe things wouldn't have happened after that. But what surprised Oram even more than that was that a familiar figure appeared in the information of the monster worm.
This familiar figure is Eve's older brother Ningir Su. It turned out that after Ningir Su left the Forest of Stars, he had been looking for a way to revive his sister Eve. And the terrible thing is that during the trip, he really found a way to make the deceased su alive, that is, with the power of the star relic. However, after reading the inside information of the Monster Worm, Orram knew that the consequences of activating the Star Relic would only bring destruction, and the destruction of the entire world.
According to the guidance of the legend, Ningir Su found the Institute of ultra-ancient times, and with the help of the power of the new star relic "Star Crown", Ningir Su reactivated the ancient research equipment. Through these devices, Ningirsu separated Eve's soul from her body and intended to secure Eve's soul to the doll. This is the way Ningirsu found on his travels to find the way to revive Eve.
However, the experiment of the deceased Su Sheng was not achieved overnight, and Ningir Su was constantly groping, and in the process of groping, as an appendage of the experiment, a batch of automatic dolls called "self-playing sacred music" was born. At the same time, with the power of the Star Relic, a strange building called the "Tower of Babel" was built, which is the stronghold of the self-playing sacred music and the laboratory of Ningirsu. And Olam, who wanted to stop Ningirsu, was also going to rush here. He had to stop Ningirsu's actions, even if it meant seeing his former comrades as enemies.
