Epic of Caterpillar

And these guys weren\'t disposable garbage either, they were very respected, high ranked Undead sent to protect her from the Netherworld Realm, or as some call it, the Necrotic Plane. The Entity\'s voice grew with frustration, as she saw the several Necrotic Magic Circles that invoked them shatter apart and disappear into ashes.

These Magic Circles formed part of her Netherworld Summon Formation within this Floating Castle, which allowed her to bring more Necrotic Essence from the Necrotic Plane. With the three powerful Necrotic Death Overlord being gone, their power stabilizing the formation were also gone, and so…

RUMBLE!

The entire thing was beginning to crumble apart!

"T-This is impossible! How come Kireina and those lowly insects following her could kill the Necrotic Death Overlord?! Even back in Genesis she wasn\'t capable of doing this! W-What sort of power is this world giving to her?!" She wondered, panicking. "Damn it!"

Elfina raised her hands and quickly controlled the formation from crumbling apart. Millions of souls flowing out of the gates to the Necrotic Plane repaired most of it, but its functions were still flawed now, and the rate of Summoned Undead have begun to deteriorate critically.

"If Kireina was able to solo a Necrotic Death Overlord, even when he was weakened within this world… This means she has already grown as strong as her Supreme Goddess counterpart, and it has barely been half a day since her death?!" The entity thought. "This is… I suppose we cannot hold back any longer, Elfina…"

"We\'ll finally end this?" Elfina wondered. "We\'ll end it all, and finally… We can find true peace."

"Hehehe… That\'s right, dear. We\'ll end it all. Your life included." The entity laughed. "Let\'s end this show once and for all."

FLAAAAASH!

Suddenly, the powers of the entity began to distort the entire Formation, which quickly began to spread across the Titan holding the castle. Both entities started fusing, forming a massive tower made of bones and flesh.

Atop the tower, a massive black crystal emerged, with Elfina right below it, glancing at it. The Crystal emanated a powerful essence, so strong and overpowering that it distorted even space itself…

"So beautiful… so this is The End." Said Elfina with fascinated eyes, which glowed bright red.

Crack… crack… CRAAAASH!

The skies themselves began rupturing apart, as enormous cracks opened in space itself, leading to an endless darkness of death. The Undead surrounding the desert were quickly turned to ashes, their souls and powers absorbed by the crystal, which continued making the Rupture in the Sky open wider.

"If I cannot kill you directly right now, Kireina, then I hope you are happy with taking half of this entire world with you!" Laughed the entity within Elfina\'s shadows. "If you only died obediently, this wouldn\'t had happened!"

…

As Kireina finished killing the Necrotic Death Overlord and sighed in relief, she glanced at her surroundings while destroying thousands of Undead at a time, quickly sensing that the other two Necrotic Death Overlord were slain by his allies.

"Oh, they have grown way stronger than I imagined. Good thing I didn\'t had to step in to help them…" Kireina felt slightly proud of her friends. "Now, I should probably- Huh?"

TRUUUUUMMMMM….!

As she made her way towards the Undead Titan while slaying as many Undead as she could, she suddenly noticed as the Undead all began to disappear, turning into ashes and having their souls and all energies sucked by the Undead Titan.

"What in the world is happening now?" Kireina sighed, seeing as the Undead Titan began taking root on the desert\'s surface.

The monstrous Undead\'s entire body started to distort and shapeshift, losing all of its humanoid shape as its bones, flesh, tendons, and other body parts stretched and formed aberrant branches and roots growing both high and deep into the ground respectively.

The entire creature took the shape of both an aberrant tree and a netherworld tower, made of rotten flesh and twisting souls by the millions, all screaming in agony as they were used as materials to form… something greater.

FLAAAASH!

A massive black crystal materialized on top of the Netherworld Tower, beginning to absorb all of this energy taken from the very Undead they summoned, and redirecting it as a black-colored lightning into the skies, beginning to shatter them open.

"It\'s shattering the skies…?!"

Crack… crack… CRAAAASH!

Kireina saw as the skies themselves began rupturing apart, as enormous cracks opened in space itself, leading to an endless darkness of death. Kireina immediately realized this wasn\'t a mere portal to the Necrotic Realm, but to a deeper part of this place, a darker void.

"Master, what is that?!" Colora arrived at Kireina\'s side, panicking after seeing such a commotion.

"It is… a portal to the Nether Void, the darkest and most dangerous place within the Necrotic Plane." Kireina sighed.

"Wait, what?! How come… Are they planning on letting the entire desert disappear into that?" Asked Black in surprise, emerging at her side.

"No, if I am correct… this would be even worse." Shadrach said. "It would consume half of this entire world, if not more. And if it is left for a while, it would simply consume everything."

"H-How do you know so much?" Black wondered.

"We learned a lot of things by battling them and eating their souls back in Genesis." Kireina said. "And well, I also ate the guy I just killed and his soul, so I got a lot of his memories and info. I\'ve figured out who\'s behind this, and also what they want… We need to regroup with everyone and stop this. The Undead are now gone, so I guess we can go all out now!"
