Massacre at Katze Plains

Massacre at Kazte Plains was an event that took place during the Annual War between the Re-Estize Kingdom and the Baharuth Empire. It is also when the Ainz Ooal Gown and the Sorcerer Kingdom officially debuted themselves to the world.

Background
Prior to the massacre, the Baharuth Empire received word of a tomb that has mysteriously appeared within the borders between their nation and the Re-Estize Kingdom. The Empire has sent Workers to investigate the tomb and report back what they may find but they never returned. Instead, two Dark Elves appeared at the castle, revealing themselves to be members of the Great Tomb of Nazarick. After killing many of the Empire's men including one of the Four Imperial Knights, the Elves demanded the ruler, Jircniv Rune Farlord El Nix to come to visit the tomb and apologized to their king, Ainz Ooal Gown for the transgression otherwise the Empire will pay the price for refusing to comply with their nation's destruction. Jircniv and his entourage arrived at the Great Tomb where they encountered and taken aback by many of the strange denizens that lived there and the power they wielded. Ainz Ooal Gown, in particular, showed his ability to raise the dead and converted them into undead warriors with supernatural ease. In addition, he possessed a vast military force and beautiful women that will put all of the New World to shame. The Emperor seemingly accepted this and proposed to Ainz an alliance between their nations which the latter agreed but after Jircniv left, in truth, he has already deemed the Elder Lich-like being a threat not just to his Empire but to the entire world and planned on using their alliance to leak information to the other Kingdoms and unite them against him and using various schemes to undermine him. Unbeknownst to him, one of Ainz's men already deduced Jircniv's treachery and informed this to his king.

At the Re-Estize Kingdom, King Ramposa III and his court were informed about Ainz Ooal Gown's existence and his participation to the Annual Wars as an ally to the Baharuth Empire. Terms had been made that should the kingdom surrendered, they must offer E-Rantel to Gown. Despite Gazef Stronoff's warning them about the dangers of the magic caster, both the Noble and Royalist factions dismissed him with only the king and Marchioness Raeven accepting what the Warrior Captain has told them. Nonetheless, the kingdom refused to lose part of their land and decided to continue the war by conscripting many of their male citizens to counter Ainz Ooal Gown.

Following this, Gazef met up with Brain Unglaus and Climb. Gazef asked what the two had been doing throughout the day. Brain and Climb explained that they traveled to E-Rantel in hopes to meet Momon and discuss about the two vampires he was hunting. Unfortunately, he wasn't there as he was taking on a high-rank request much to Gazef's disappointment who thought that the Raven Black Hero can be of help to repel the Empire and Ainz Ooal Gown. During their conversation, Climb informed them that he will be wearing his usual armor despite the obvious disadvantages it presented under orders of his mistress, Princess Renner who was secretly working with Ainz to spare the young knight from harm. Gazef gave the same advice he said to the court about Ainz Ooal Gown to his comrades and the two will made sure to prepare themselves whatever would throw at them by the man who saved Gazef's life. Gazef then mused to them that should all three of them survived, they should have drinks. Meanwhile, King Ramposa had sent his son, Barbro to head to Carne Village. The reason for this was to gather information about Ainz so that the Re-Estize Kingdom can offer a peaceful resolution to the man and Ramposa secretly wanting to spare his son from death. This action proved fatal as Barbro disobeyed his father and had the village be attacked by his men so that he could use the people as hostages to have Ainz surrender. The people of Carne Village are understandably angered at this and chose to fight on behalf of the magic caster who was their savior, summoning the Goblin Army that wiped out many of their enemies. Barbro and his men retreated in terror. Later that night, Lupusregina Beta visited Barbro who begged to be spared but this is met with deaf ears as the Battle Maid explained that her king has deemed the First Prince useless to his plans and must be punished for his actions. Goblins slaughtered what was left of Barbro's army and the prince died thirty minutes after Lupusregina tortured him. At the Imperial Castrum, Nimble Arc Dale Anoch and the Imperial Knights awaited for Ainz Ooal Gown's arrival, under secret orders by Emperor Jircniv to spy on the magic caster and determine his power. Piecing together what he had seen, the Emperor believed that Ainz Ooal Gown can at least kill a thousand men and using that theory, he decided the best course of action is to request Ainz to use his strongest spell and show the world the threat that he posed. After that, Nimble and the Imperial Knights will push away what remained of Re-Estize's army. Ainz Ooal Gown finally arrived along with his escort, Mare Bello Fiore. Ainz was also eager to follow Jircniv's suggestion. His main goal was to learn the existence of other Players like him and hopefully, one might be his comrades. He will reveal himself out in the open all while performing the spell. This tactic is to draw out anyone who recognized the spell and deploy the right countermeasures to prevent it. That will confirm Ainz's questions. After greeting his allies, Ainz ordered his army to come and much to the Imperials' shock, the army was comprised of Death Knights and Soul Eaters, monsters in legends that have wiped out entire countries.

Battle
The Annual Wars has begun. The Re-Estize Kingdom arrived on the battlefield, bringing in their Royal Army comprised of 245,000 soldiers. On the side of the Baharuth Empire, they had brought six legions of the Imperial Army to confront the opposing side. The only one who has yet to appear was Ainz Ooal Gown.

Returning to the Re-Estize Kingdom, King Ramposa III was conversing with the nobles who believed that with their sheer numbers, they have a significant advantage over the Empire and will obtain victory. This mindset also extended to the commanders such as Marquis Boullope who commanded the left wing of the Royal Army. While glad that morale is high, the king isn't fully confident about the situation.

At the front, Gazef met up with Marquis Raeven who had his team of Ex-Adventurers as his bodyguards. The two noticed that the Imperial Army has yet to make a move against them which was unlike them during the past skirmishes. Gazef believed that it was because of Ainz Ooal Gown. Raeven then noticed that Gazef was wearing four of the five National Treasures of the Re-Estize Kingdom consisting of the Gauntlets of Vitality, Amulet of Immortality, Guardian Armor and Razor Edge. Gazef explained that King Ramposa ordered him to wear them despite how he felt about this and how this would affect the nobles later on. Raeven understood that this decision was born from Gazef's warnings and Ramposa was taking precautions in case the magic caster was just as powerful the Warrior Captain claimed him to be. As they are discussing what the Imperial Army and Ainz Ooal Gown have as trump cards against them, both came to an agreement that they must survive this battle, with Raeven intending to return to his wife and son. Just then, the Imperial Army started to move. They were not attacking but merely moving aside to allow the main doors of their base to Imperial Castrum. Once they did, monstrous creatures began to march out of the base. The Royal Army were at lost for words as they stared upon 200 Death Knights and 300 Death Warriors, all mounted on the giant skeletal horses, Soul Eaters. The Empire were trying their best not to panic as their fear has been building up ever since these new forces arrived. The Ex-Adventurers reunited with Raeven and informed him about the Soul Eaters' identity and the dangers they pose. Most of the Royal Army began to realize the magnitude of the truth behind Gazef's words but it was a short time as, after the army of the monsters, three people were the last to exit the Imperial Castrum; Nimble of the Imperial Knights, Mare the Dark Elf and the Sorcerer King, Ainz Ooal Gown.

Gazef muttered Ainz's name allowing Raeven to now know who the magic caster was. Ainz and his escorts stepped toward the front lines. Once they halted, large magic circles started to appear around them. The Royal Army were surprised once more, having not seen such magic of this scale. Raeven and the Ex-Adventurers returned to their unit, deciding that the battle was already lost. Gazef stayed behind to protect King Ramposa and the Royal Army from the attack. However, Marquis Boullope foolishly led the left wing to charge at the Imperial forces. Ainz looked on at the Royal Army and their scared and confused reactions were enough to confirm to him that there are no other Players present. He had already prepared a Cash Item to accelerate the process of his super-tier magic. Looking back about his plan, Ainz had thought about the massive casualties that was about to take place but he truly felt nothing about it, whether it was because held no personal attachment to most of Re-Estize or his time with Nazarick and this world has started to take affect on him. Still, his mission was there. He has to take action to allow himself and his tomb to prosper. Crushing the Cash Item in his hand, Ainz Ooal Gown unleashed the super-tier magic spell 'Ia Shub-Niggurath'. A dark wave burst forth and headed toward the Royal Army's left wing. In an instant, the wave killed Boullope and his men whose corpses fell to the ground.

Both the Re-Estize Kingdom and the Baharuth Empire stared in horror at what remain of the former's left wing. Ainz noticed Nimble's look of fear and asked if anything was wrong. Nimble calmed himself and explained that he was surprised how effective the super-tier magic spell was, killing 70,000 men in matter of seconds. Deep in his mind, Nimble dreaded what would happened if Ainz unleashed his might onto his nation. Suddenly, Ainz laughed at that statement. Nimble turned around and apologized, hoping he did not offend the Sorcerer King. Ainz corrected Nimble that the event that he watched was only part of the spell. The spell required sacrificial offerings as fuel to complete it. Now that it was done, the real spell was about to start much to Nimble's growing fear.

Up at the clouds, a black sphere appeared above the corpses of the left wing. It dropped onto ground and began consuming all of the bodies. When it was done, taking its place were eldritch abominations that looked like black mass with elephant-like legs, human-like teeth and dozens of tentacles covered over their bodies. Ainz revealed to his allies that they were called Dark Young and he was surprised that he has summoned five of them, an achievement surpassing the one that has summoned two. Only Mare truly praised his king while others tried to hide their discomfort. Satisfied that he has achieved such an momentous accomplishment, Ainz decided not to send them away and had ordered the Dark Young to attack the Royal Army but spare four individuals their master has selected. The Royal Army were ordered to ready their spears and attack the Dark Young although most were in paralysis upon seeing the beasts, refusing to believe that such things existed. When the Dark Young arrived, what was once thought to be a battle turned into a massacre. The Dark Young used their massive hoofs and tentacles to wipe out hundreds of the soldiers. The surviving commanders ordered a retreat with the soldiers complied without question but all proved to be futile. The bloodcurdling screams were everywhere followed by the sound of an impact that caused body parts exploding that can only be described as "Splat!". This was a process repeated over and over again across the battlefield.

Marquis Raeven ordered his men to retreat before he and his team of Ex-Adventurers fled as well. Raeven could only curse himself for not realizing enough the power of Ainz Ooal Gown who he deemed a monster that must be stopped otherwise the future of Re-Estize will fall apart. Then, one of the Dark Young started following them. Left with no options, the Ex-Adventurers stayed behind to fight it and sacrificed themselves to allow a regretful Raeven the time to escape its pursuit. Unknown to Raeven and the fallen men, Ainz had ordered the Dark Young to spare the marquis from their wrath.

The Empire watched the slaughter, trembling in terror. They no longer cared that the Re-Estize Kingdom was their enemy and only begged all of them to escape. Ainz declared the charade was over and the Empire turned to him as he revealed his true skeletal appearance. This frightened them as they now realized they had just affiliated themselves with an inhuman being. Ainz demanded applause for his might that he brought upon the Katze Plains. Mare clapped in ecstatic joy for his king and soon, the Imperial Army joined as well. Suddenly, one of the Dark Young is heading towards the Imperial Castrum. The panicked Empire clapped harder and praised more to Ainz Ooal Gown until eventually, they lost the will and fled with a portion of the soldiers trampled to death by their own scared comrades. Because of this, the Empire has breached the agreement they made with Ainz but he was in a joyful mood and excused it. The Dark Young arrived and lifted its master onto is back, intending to transport him through the terrain and allow him to finish wiping out the remaining enemy forces. Nimble accidentally spoke out loud if Ainz Ooal Gown was a demon but the Sorcerer King rebutted that reply and told him that he is not a demon but the Undead.

The Re-Estize Kingdom was left in disarray. The surviving nobles had ran away leaving only King Ramposa and what was left of the Royal Army standing against Ainz Ooal Gown. Brain and Climb managed to survive the Dark Young and reached Ramposa's camp. The king refused to leave, deciding to stay and saw this through. He was eventually talked out of it by Vice Captain, Brain and Climb. Their next move was to escort King Ramposa out of the battlefield. Brain and Climb chose to distract the Dark Young allowing the King and the remaining men to escape. Before they left, Brain asked a reward for Climb and that should they survive the onslaught, his friend will have Renner's hand in marriage much to Climb's embarrassment and King Ramposa's delight who agreed with the terms.

Outside, Gazef head into battle to confront the abominations to buy everyone the time they needed to flee. Gazef swung his sword and tried as he could to halt their advancement but despite being bestowed with powerful items, Gazef was no match against the Dark Young who were barely affected by the attacks. Before Gazef could continue the assault, the Warrior Captain witnessed Ainz Ooal Gown riding on top one of the creatures that was heading towards him. He also realized his savior's true identity as an undead being. Brain and Climb reunited with Gazef and prepared to fight alongside him but they didn't have to as Ainz had ordered the Dark Young to halt.

Reaching his destination, Ainz levitated from the Dark Young and landed on the ground below. The Sorcerer King and Warrior Captain exchanged greetings, both felt it has been a long time they had seen each other. Still confused, Gazef asked why Ainz was here. The latter answered that he wanted to offer the man a deal; that he swore allegiance to him and in return, the assault by the Dark Young will ceased. Gazef however was not able to do that, knowing that this will lead the nobles to take serious actions against King Ramposa and the commoners. Instead, Gazef refused and then pointed his sword at Ainz Ooal Gown and demanded a duel against the Sorcerer King. This left Gazef's comrades and even Ainz to be shocked at what the man was doing. Ainz warned him that this action was futile and will lead to his demise but Gazef was prepared for this and he believe there was a chance since the Sorcerer King was within the reach of his sword. Ainz admitted that they are physical equals but the difference between their power was high. He demonstrated it by ordering his Dark Young to launch its tentacles which Gazef was barely able to notice.

He asked the Warrior Captain if his reluctance to kill him has made him arrogant. Gazef denied that, stating that he was only fulfilling his duty as a servant to the king and could not break his code. Despite being given another warning and heard the desperate pleas of his friends who wanted to join him in the fight, Gazef stood by with his resolve to face Ainz alone. Seeing that this was the man's final decision, Ainz reluctantly permitted the duel which he called 'PVP'. Ainz then took notice of Gazef's sword and asked to inspect it. Gazef complied and Ainz informed him that while the Razor Edge won't leave significant damage to him but in certain conditions, it was possible that the weapon can kill him thus making the duel a fair fight.

Gazef made another request that if he died, he did not want to be resurrected. Ainz agreed to it. After making Climb the one to signal the fight, Ainz and Gazef prepared themselves. When the bell rang, Gazef charged at Ainz but nothing happened as time suddenly stopped. Ainz revealed to the frozen and unknowing Gazef that during 'PVPs', one must prepare counter spells should time spells were used. Ainz said his farewells to the Warrior Captain before using the spell, True Death, killing Gazed Stronoff.

When time returned, Brain and Climb watched Gazef suddenly fell. The two did not know what has happened and beg Gazef to stand up. Ainz informed them that their friend is dead. As Brain and Climb head toward Gazef's body and grief over him, Ainz ease their pain by telling them that the man died like a true warrior and because of his act of heroism, he decided not to continue the pursuit to respect it. Ainz was ready to prepare a proper burial for him but Brain politely decline and that he and Climb will made sure of it. The Sorcerer King accepted it but informed the two that a high-tier spell was required to resurrect Gazef, a spell which they and the entirety of the New World do not possessed. As he left the battlefield, Ainz made one final warning that E-Rantel must be offered to him or he will command his Dark Young to ravage their kingdom. Brain decided to carry Gazef's body while Climb took care of his belongings.

Aftermath
The battle was over with the Empire and Ainz Ooal Gown claiming victory. Many men from the Royalist Faction, Noble Faction, soldiers and conscripts lost their lives. 70,000 had been killed by the super-tier magic and following that, another 100,000 was added due to the Dark Young totaling up to 170,000 killed. The King and the survivors managed to return to E-Rantel but not without suffering major wounds. Their soldiers are severely injured or traumatized what they had experienced. Families are left orphaned due to the deaths of their fathers and husbands. Since many nobles including the first sons had been killed by either the spell or the monsters, this left for the second heirs to take over their late relatives' former positions. King Ramposa had been informed about Gazef and is struck with intense sadness over the loss of his friend. With Prince Barbro having yet to return from his mission, Adventurers will be hired to find him.

The King and his court reached a unanimous decision and that is to immediately relinquished E-Rantel to Ainz Ooal Gown, in an effort to save the Re-Estize Kingdom. Reports came back to the Baharuth Empire. Jircniv was horrified what he had learned. He had severely underestimated Ainz Ooal Gown and now his plans had produced the opposite results. Because of Ainz's use of that spell, he had single handedly crippled an entire kingdom to ruin and the news will spread throughout the other neighboring countries who will be highly reluctant to stand against the Sorcerer King. The Empire were now on their own and the Emperor grew paranoid, fearing what the monstrous entity would do to him and his nation should he learned of their deception.

Some time passed, the now abandoned E-Rantel was left defenseless allowing the forces of Narzarick to enter the city, unopposed. A parade was held there lead by Albedo to commemorate Ainz's victory but none of E-Rantel's citizens appeared before him, scared of their new ruler. Then, a boy exited out of his house and attempted to throw a rock at Ainz but only able to hit the Death Knight. He demanded Ainz to give him back his father and called the Sorcerer King a monster. The boy's mother stepped in to protect her son and begged Ainz and the creatures for forgiveness. Albedo refused to accept what that boy had done and she declared that he must be punished with death.

Suddenly, help came in the form of Momon who defended the mother and child from Albedo. The two exchanged hateful words to one another before preparing to fight to the death. That is until Ainz Ooal Gown came and calmed Albedo down to inform her about something. Albedo smiled and turned to Momon. She informed that her king has a proposal for him. If the Adamantite ranked Adventurer swore loyalty to the Sorcerer King, then all the lives of E-Rantel will be spared from retribution but if he refused, the battle will continue and collateral damage and casualties will be high. Momon accepted those offers, having left with no other options. Truthfully, this was all part of the Sorcerer Kingdom's machinations. Demiurge had hypnotized the boy to commit the act forcing the Raven Black Hero to intervene and be forced into servitude. The boy's condition will be blamed on the Slane Theocracy, ensuring the nation will be discredited and preventing anyone in E-Rantel to ask for their aid. Momon (an identity worn by Ainz Ooal Gown and Pandora's Actor) will stay and calm the citizens from revolting and spy on anyone who dares to do it. With that, the Sorcerer Kingdom was established and it has become a land of peace.
