The Demon God's Slaughter

(This Chapter is Quite Quick Paced as I don't want to drag this Arc out too much. I want to get to the Evie Atolde War and then Romonus finding a way out of Dragon Deus to other worlds.)

Once Romonus finished his Campaign against Heaven and God, and all of the Angels had been killed he got to looting. First, he claimed all of the souls of the dead Angels that survived the Phosphex and he set his Demons loose to pillage. Once all of God's treasures were taken, including the Trees of Knowledge and Life his Demons were happy. 

While Angel souls were one of the best commodities, he also harvested the souls of the believers of God in Heaven. That increased his soul stores by a substantial amount. Though, his Demons also collected the Angel's Halos, Weapons, Armor, and even wings were cut off.

Once Heaven was taken for all it was worth and the Garden of Eden was ripped out Romonus began to absorb Heaven itself. Heaven had been formed from God's Divinity essentially making it part of him. 

With the Death of its Master, Romonus wanted to form his own Divine Domain. He could have warped Heaven to his needs, but he didn't want to bother so he absorbed the energy that God had used to create Heaven not to let any of it go to waste. 

When he was done, Heaven was just a memory as the Angels in Heaven were extinct. Once the Campaign was over, the Demons began to return to Lucifade with their dark offerings to their master. 

More Skulls for the Skull Throne were added to the mountain in Lucifade. Aside from Lilith and Leviathan, no one lived in Lucifade as Romonus had killed them all. The two women watched as Angelic skulls were pilled high. 

Lilith merely sighed and avoided looking at the Demons, while Leviathan began to feel something. With each skull she saw added, she began to rub her neck. She wondered if her end would simply end with her skull on that throne. 

Lost to the pile, never to be remembered in the long run. Regardless, once the skulls were offered to Romonus' Skull Throne, and the Campaign in Heaven was done, Romonus moved his Legion against another Pantheon. 

This time, he moved against the Celtic Realms which was where Silvana's Mother and Patron god were from. Unlike the Greek Pantheon and Heaven who were caught unaware, the Celtic Pantheon had brought their army to face him directly. 

All of the gods had prepared as best they could because there was truly no being on the planet who could oppose Romonus in single combat. Even still, the gods knew that it was better to die in combat than to die like cattle. 

When the grand army of the Celtic Pantheon had formed, Romonus was tempted to release his Demonic Legions without mercy. However, it seemed that Kharn was feeling restless so he allowed the Badger to start the attack. 

When the small Badger had walked forward on his now longer legs the Celtic Army felt they were being mocked. How could this small creature possibly kill their Divine Army? Yet, they soon realized that it would have been better to be killed by the Demons. 

The instant Kharn released his restraints, his Rage Heart that never stopped burning was released. A tidal wave of Rage began to burst from the Badger causing his body to bulge and twist. Kharn during his time adapting to Romonus' Godly Soul had focused on his Rage Heart. 

Now, his rage came infused with Infernal Divinity, and through the pact he shared with his Master, was always ready for a fight. In a matter of moments, Kharn went from being a small little critter with the heart of a Berserker to a creature the size of a Titan. 

In a grand display of carnage, he charged as a cyclone of blood, rage, and hate into the heart of the army. Each swipe of his crystalline claws launched waves of rage energy killing all. The gods themselves rushed at this creature to put him down, but even their Divine Weapons would not piece Kharn's thick fur and skin. 

When they did pierce through, it was only a few inches which spilled blood boiling from the rage felt by the Badger every second or every day. Once the attack was started, Romonus set his Demons loose who bellowed great oaths of blood and rushed in after Kharn. 

Grimaldus instantly rushed to fight next to Kharn as his living mechanical flesh began to expand much like Kharn. Once he was the same size as Kharn, he released his deadly weapons except Phosphex. 

Using that substance freely would cause it to make the planet uninhabitable too soon. If used without consideration the stuff would burn for decades without going out. Even in the Grim Darkness of 40k, Phosphex is practically outlawed because of the danger. 

However, that did not mean that Kharn's multitude of other deadly weapons were not up to the task of massaging worlds. Including the Forbidden Magics of Azi Dahaka and even Mephiston the weakest of Romonus' Familiars was a beast in combat. 

In a matter of a few minutes, the entire army of the Celtic gods were butchered when they faced Romonus' Legion in Combat. Every single one of his Demons had been formed from Romonus' Immortal self, so they shared his immortality. 

Only by fully destroying the bodies, souls, and essences of the Demons could they be put down, but Romonus always healed them before they reached that point. Even if they were killed, he could turn back time to before they died and bring them back. 

This essentially made his army, a giant army of Immortals that would regenerate from any wound, felt no pain, and were fiercely dedicated to their slaughter. Once released into the battle, they went in spurred by the brutality of the Angry Ones. 

Even Azi Dahaka began to buff them while he stayed back with Romonus standing on his back. With all these advantages, the armies of the Celtic gods were massacred in a few short brutal minutes. 

The gods who went against Romonus were not only killed but also refined to enhance the abillities of his lovers. To upgrade his Domains, he absorbed Arawan not just to upgrade his Battle Domain, but also his Death Domain. 

Arawan was just one god who fell as several other gods and Spirits of Death existed in the Celtic Pantheon. Some of them were also gods of War and Battle which made them even better material for Romonus. 

Donn, Saint Mortain two other gods of Death aside from Arawan who fell. For gods of War, Romonus slayed Neit, The Morrigan, Caturix, and Mars Cnabetius four Celtic War Deities to enhance his Battle Domain. 

Already more than 20 gods had been consumed and Romonus' power was swelling to an absurd degree. Romonus checked to make sure that he was not harming himself, but he was perfectly fine. 

While he was in the Celtic Lands, he didn't even spare Balor, who would one day be sealed into Gasper Forbbiden Balor View. His Destructive power was used to upgrade the Destruction Domain. He also helps his lovers with him. For Akeno, she killed the Lightning and Storm God Taranis and he helped her absorb his Divine Essence.

Nisselred with the aid of the Demons, tracked down and in single combat, killed Cailleach the Personification of Winter. Seekvaira after absorbing Kronus, had been amped up on his Divine Energy and had her Time Abillities enhanced to absurd levels. Using this new power, she fought Dagda, the brother of Lugh the Son god, the god of the Seasons and Time. 

Speaking of Lugh, Romonus absorbed his Divine Essence as well as it would come into use later when he built his sun forge. Though, Romonus was proud that his lovers did not need him to fight for them. 

All of them after many years of training in the Time Chamber and Valerie's modifications were absolute powerhouses. Even more so after consuming gods that matched their specific abillities. 

Romonus would need to help the girls who set off on their own to do the same unless they were doing this already. Regardless, Natsume didn't need any gods to consume as it was better for her to just feed Griffin the Qiongqi. 

The more the Evil Fiend fed, the more power was available to her. Thanks to her strong will, she was not affected by the brutal thoughts of her Sacred Gear. However, he could tell that she was not holding back as much as before. 

It was like she was allowing herself to be affected on purpose. He would need to ask her about it later, but regardless, he decided to hold off. While he was here, he did collect more gods that matched the abillities of his lovers and kept them in stasis in his giant spatial ring. 

He also had to deal with the Sirzech's Peerage had taken with him. They could be useful in the long run, but he still had not decided what to do with them yet. However, he did not delay long and moved to continue his campaign. This time, he moved over the sea to the Americas.

There, he waged a war against the Aztec gods and the gods of the Native Americans, and then he went to South America to fight another War against the Incan Gods. 

In quick succession, one after the other, those Pantheons and their armies were destroyed. When those Pantheons were slaughtered along with the Greeks, Celtics, and Christians, Romonus once more moved. This time, to Africa which made him feel like he was Alexander The Great waging a Campaign against the known world.

In his case, he was waging war against a world without mercy. With each successful, campaign, Romonus' Power continued to surge ever higher Not only that, but the Skull Throne in Lucifade grew with each battle. The Demons kept adding to it and by now, Lilith and Leviathan who had remained in Lucifade were seeing that the skull offerings were starting to speed up. 

The speed at which Romonus fought and the brutality of it had increased. Now, the skulls numbered in the millions. Leviathan in particular had decided to get rid of any thought of retribution. If she even tried, she knew that her skull would be added to that sick throne by those Demons. As she watched them pile the skulls higher and higher she could tell they felt pure joy at this. 

It had a truly profound effect on her as currently, Romonus was off-waging another campaign against the Germanic Gods. Leviathan and Lilith were standing near the Skull Throne as Demons began to open portals as they dropped pile after pile of skulls. 

Some were the skulls of gods, others were the blessed Divine Soldiers of the gods while others were just normal mortals who decided to fight against them. Lilith crossed her arms as she looked at Leviathan at her feet. The former Satan kneeled at the Skull Throne with her head down. 

She clasped her hands together and began to pray to Romonus of all people. 

"Are you praying?" 

Leviathan didn't open her eyes, but she nodded. 

"I am." 

"I didn't take you for a beliver, not after what happened with the rebellion and things." 

Leviathan opened her eyes and stood up before turning around and turning her back to the skull throne. 

"Lilith, look at what this is?" 

Lilith looked at the skull throne as a portal opened with several Demon Knights and even a Demon Prince dropping off his offering of skulls. 

"A pile of Skulls?" 

The Demon Prince snarled as he turned his head. With a snarl, he corrected her. 

"Not a pile. A SKULL THRONE!" 

At his bellow, all the other Demons bellowed back. 

"SKULLS FOR THE SKULL THRONE! SOULS FOR THE MASTER!"

Lilith bowed. 

"I apologize for the slight." 

With a snarl, the Demon Prince ignored her after dropping off his skulls. Once the Demons were finished, they returned to Romonus for the next campaign in Australia. He was not going to spare a single Pantheon, no matter where they were. 

All that mattered was power, and he would get it at any cost.
