Destruction of the Seraph Civilization

The destruction of the seraph civilization was at least a city-wide event in which the many tall crystalline like buildings that made up the city were destroyed utterly. Every last seraph that lived within the city was murdered, with their souls bound to the planet. Where ending the Earth was mentioned, the calamity of meteor fire that devastated both the city and its inhabitants was likely a planet wide event that resulted in the extinction of the various species of dinosaurs that were alive at that point in time.

Background
Before recorded time, long before humans had evolved, seraphs were active across various worlds. Where there were Satellite Kingdoms spread across planets in the galaxy, the designated Sol System First Satellite Kingdom: Earth was one such outpost where seraphs along with homunculi had established a civilization. Where the Babel Project was being developed, which involved seraphs gathering light into the Tower of Babel, there was also technology such as Unrailed Elevator Technology that was also in existence. As light was the source of God's power it could be inferred that they wanted seraphs to gather light with a goal for them to be able to return to paradise on the Sun where they were located.

A plague was affecting seraphs however, and where they were capable of perishing it would reach the point where over half of the Earth kingdom's population would have passed away. Concerned at this, Sika Madu created Mikaela as a means of identifying a cure for the plague. Although creating life was one of the three gravest taboos that could not be broken it would appear that this was not noticed by those who would enact punishment against that. Distraught at Mikaela having died when that occured, after angels close to him such as Paimon and Bael had passed away, Sika Madu considered the further losses which also included Belial.

While Sika Madu doubted the purpose of returning to paradise given the numbers that were deceased and whether it really would be paradise without them, he informed his remaining human appearing angels Amon, along with Naberius, then Astaroth, and Bathin, with Raum as well that they were to return to paradise now that the Tower of Babel had reached the required amount of light. Instead, Sika Madu revealed his foremost intent to an unresponsive God.

Meaning to use the light gathered in Babel tower to instead resurrect the angels who had died so that they could all return to paradise together, Sika Madu tasked the homunculus named Yu to darken the light for that purpose. The halos of light floating around the Tower of Babel in Space were successfully darkened. At that point the homunculus was targeted by trumpet wielding seraphs who appeared.

 * The many seraphs that were within the Earth kingdom
 * Naberius
 * Astaroth
 * Raum
 * Bathin
 * Amon

Story
Upon the resurrection attempt being detected, at least seven seraphs armed with trumpets gathered light which blasted the homunculus carrying out the task apart. The seraphs communicated that a taboo had been broken and that punishment was being dispensed. The large sphere of light that was generated shone bright to the point it resembled a sun and emitted electrical surges. A lightning bolt from that blasted downwards to fracture the Tower of Babel apart before connecting with Sika Madu to unceasingly burn him.

Where a seraph based strike of lightning had collapsed the Tower of Babel, the damage to the other constructions of the settlement on Earth would come from a different force. A humanoid angel descended to Earth and announced that Sika Madu had condemned his followers to Hell. Additionally, the angel stated this was the end of Earth too. By clicking his fingers the angel could fill the sky with many streaks of fire which came crashing down.

Each of these fire streaks had the force to break through bone, and continue their trajectory to break into the ground. Two angels, Naberius and Bathin were seen to have perished this way. While their deaths were not viewed, it appears the case that Astaroth and Raum were also murdered this way. The continuous rain of destructive fire broke apart the buildings of the seraph civilization.

A sustained channel of electricity continue to pin Sika Madu in place and kept him burning alive. Amon was said to be permitted by the unnamed angel to reach Sika Madu's location before being struck by lightning in front of him. At this point the seraphs that were in Space joined the humanoid angel on the ground to reveal further details of Sika Madu's punishment, that all the angels have been destroyed and that their souls are bound to this planet.

Aftermath
The seraph civilization and beings within in were all wiped out despite how long they had worked to gather light for God and return to paradise. Sika Madu was kept alive having been turned into an undead that could not die. His eternal punishment for attempting resurrection was for him to forever burn by sunlight that he was now affected by. Sika Madu experienced this alone on a barren world for millennia until he was able to form darkness to protect him from the light.

The destruction of the seraph civilization and the loss of the light collected into the Tower of Babel would not deter Sika Madu from his goal of resurrecting the fallen angels. Instead he would seek different methods. Accordingly, Sika Madu along with the homunculus named Yu brought the first humans seen on Earth where they would go on to establish dominance over the planet.
