Epic of Caterpillar

The death of an Archdemon such as Satan, who has been sticking around Hell since its conception, didn't go unnoticed. The Archdemons were the first to notice it. All four of them that didn't participate, but that were actively cooperating together with Satan to go against Mammon and Kireina, and also Lucifer, who has been keeping a mostly neutral stance within hell for eons now.

Within the Layer of Sloth, Belphegor gasped in utter disbelief the moment he heard the screams of utter agony coming from Satan. His soul was shattered and then eaten, and the Primordial Sin he carried divided and shared between two Vessels!

"Ah, I was having such a good dream! What was that noise?!"

Inside of the Layer of Lust, Asmodeus, who found themselves resting inside a big bed surrounded by all kinds of Succubus and Incubi opened their eyes wide, noticing the death of one of their strongest fighters, Satan!

"Satan died?! How is this possible?! How did that fool let himself die!"

Inside the deepest seas of the Layer of Envy, where dark oceans swallowed it all, a gigantic being opened their bright, red eyes. Leviathan emerged from the depths of his oceanic Layer, looking into the red and dark skies of hell.

"Satan! He died?!"

And lastly, in the deepest parts of Hell, only right above the Layer of Pride controlled by Lucifer, a world of countless and monstrous beasts and insects eating one another in wild, infernal savannahs and jungles, a gigantic fly aberration emerged from their black castle.

"That fool of Satan… I can't believe he would let himself get killed!"

All four of these Archdemons, which created the Five Sins Alliance between them and Satan, were deeply shocked and furious that Satan perished! He was someone that was pretty much their leader, and now that he had been suddenly slain, they were left in shambles.

The reason why they had formed this Alliance was to dethrone Mammon and eventually Lucifer himself. They wanted all of Hell for themselves, and to invade the rest of the Universe with their demons. If they combined their powers, Genesis itself would become easily consumed by their armies of demons.

The very reason why such an invasion was being delayed was because Lucifer himself had created a Divine Avatar within Genesis and was acting as the Supreme God of Space and Creation. However, with her not being there anymore, Genesis was left much more vulnerable than Lucifer could have imagined.

However, while planning for that great invasion, the plan shifted to Satan wanting to take the Dual Realm Core from the two colliding Realm. Using the Demonic Tower left behind by Kireina, which Satan "hacked" using the combined powers of all five Archdemons, he invaded the colliding Realms and attempted to take the great prize for himself.

However, even with his immense army and his many and powerful generals, he was defeated, Kireina's faction completely humiliated him, and he was forced to go back to Hell once more.

Until now, using the still strong army he had within his Layer, and with the new armor and weapons given to him by the Outer Gods' faction, he decided to aim to destroy Mammon's Layer, kill him, and absorb his Primordial Sin.

Why? Because he knew Kireina was busy now inside of the world of Abyss!

Therefore, he believed he could do as he pleased.

Unfortunately, fate semes to hate Satan, because Kireina was called by Mammon, and she came as if nothing. Somehow, even though she was inside of Abyss and coming to Hell out of nowhere shouldn't be feasibly possible.

Yet, at the end, she did. She defeated his army with ease using her family and troops, and then, killed him with the help of Mammon. The Archdemons lamented how much of a fool Satan was.

"He was driven by his own sin, but even then, he became too reckless! What was going on through that fool's head to just get inside another Sin Layer?! No matter how weak Mammon might be, he was still the Ruler of that Layer's Laws!" Groaned Beelzebub.

The four Archdemons that were part of the alliance gathered their Demonic Astral Projections within the Archdemonic Palace, a place located in the first Layer of Hell, simply named Limbo, or the "deserted wastelands", where the weakest demon tribes and demonic beasts roamed everywhere.

This was a lawless Layer with no Archdemon that dominated it, this was because it was the entrance of Hell, and Lucifer did not allow anybody to take over it. It was a nexus that connected all layers, there were palaces and portals, each one leading to a different Layer of Hell.

Kireina had come here in the past in her first incursion to Hell, searching for the way to enter Mammon's Layer of Greed, it was a rather entertaining Adventure, where she battled all kind of demonic beasts, met both fierce and gentle demons, and learned about ancient demonic cultures and tribes that once lived through its wastelands, when these lands were much more prosperous.

And this Layer was the major gathering place of all the Archdemon Alliance.

"I can't believe it, even if weakened, Satan was still tremendously strong! How is it possible for him to die?!" Leviathan screamed. "I simply cannot accept this outcome! He has wasted our resources for nothing! Now that he's dead, Mammon and Kireina somehow divided his sin, are they two the Archdemons of Wrath now?! Satan's whole Layer now belongs to them! I wanted it for myself! All the Demonic Treasures, all the Land, all the Soldiers! Arrgh!" He was full of envy.

"This is certainly not good at all…" Asmodeus gave a disappointed sigh. "Now that it is just the four of us, what do we do? Should be continue this alliance, or… we go back to how we were before?"

"Hmm, it is really surprising that Satan died, yes." Belphegor spoke with sleepy eyes. "But why are you guys so… annoyed and disappointed? Should it truly matter? Satan might have been the one that made the alliance but… Like, he wasn't the one leading us. It was the Usurpers of Destiny."

The Archdemons eyes squinted. They knew this already, but nobody was saying a word until their lazy friend mentioned that.
