Fall of the Re-Estize Kingdom

Fall of the Re-Estize Kingdom was a war between the Re-Estize Kingdom and the Sorcerer Kingdom that resulted in the dissolution of the former as an independent state. The Argland Council State and Adventurer's Guild also joined the conflict on the side of the Kingdom.

Background
The war itself was triggered by the bad actions by a single Nobleman of the Re-Estize Kingdom's New Faction. This was an attempt to increase the grain prices that the Sorcerer Kingdom had deflated due to their mass-produced high-quality grain imported to the Re-Estize Kingdom in order to turn a profit for his domain. His plan was to rob the Sorcerer Kingdom's Grain Transports in order to acquire it for himself, and cause a shortage of the product. At the same time, deflate the grain prices to make a profit from his own inferior stock and make even more profit by selling the stolen grains as his own product.

In other words, this incredibly foolish plot was hatched by the Nobleman in question together with the assistance of two other Barons. They all did this believing that, even if a war of retribution should break out between their nation and the Sorcerer Kingdom, the enemy nation does not possess the necessary numbers to invade the Kingdom. Even if they did only the territories and domains in the Kingdom's borders would be taken, far away from their own domains. Thus, the two felt safe enough to help their "leader" in his scheme and simply stand back in the sidelines as he did the actual deed in order to prevent themselves from being identified or connected to him should the ploy backfire.

Due to the lack of loyalty from the grain transport's guards, who opted to peacefully leave rather than fight off the thieves, the nobleman and his serfs managed to easily acquire the grains for himself. More-ever because of his lack of foresight or insight, the nobleman in question didn't even bother hiding his involvement to the incident. Even going so far as to arrogantly/foolishly flaunt the Sorcerer Kingdom's flag as a "War Prize" based on his successful "Battle of Conquest" against the Sorcerer Kingdom, believing that it would garner him support and praise back at the Royal Capital and not bother hiding his actions at all.

Caught completely off guard by this unexpected occurrence, the Sorcerer Kingdom had initially thought that this incident was the doing of another unknown third party who had manipulated or mind controlled the noble in question in order to initiate a complex plot. Hence, they immediately began preparing counter measures to this "new enemy" before the Sorcerer King accurately figured out that it was in fact nothing more than the Nobleman in question's own stupidity and vanity getting the better of him. Due to their prior plans of conquering the kingdom anyway using more peaceful methods now being ruined because of that nobleman's actions, the Sorcerer Kingdom thus then decided to further expand their initial plans further and take full advantage of the situation in order to make an example of the Re-Estize Kingdom as well as conquer it. This was done so in order to send a message to all other nation not to antagonize them or underestimate the Sorcerer Kingdom as the Re-Estize Kingdom so foolishly had.

Sorcerer Kingdom's Covert Invasion
The Sorcerer Kingdom decided to attack earlier than announced. Elder Liches attacked one city, while frost dragons airdropped multiple undead on another. Mare was responsible for taking countless lives with his nature magic and reducing much of the kingdom to rubble. Demiurge used a network of shadow demons to prevent the capital from finding out about these attacks until it was too late. Many nobles including Marquis Raeven were coerced into switching sides by Albedo for the sake of their families and the inhabitants of their territories.

Battle of E-Naüru
The site of the northern campaign of the Sorcerer Kingdom against the Re-Estize Kingdom. The Sorcerer King sought to cut the Kingdom from allying with or leaving a path to the Argland Council State. The city of E-Naüru was defended by a coalition of adventurers led by Four Armaments. In the end, the battle ended in the Kingdom's victory after Azuth Aindra defeated the undead commanders of the army.

Royal Coup
Despite King Ramposa III insistence that there could still be a peaceful resolve with the Sorcerer Kingdom. However his son and his retainers believed that a peaceful resolution had long since passed. To prepare their country for war, the Crown Prince led a quiet coup against his father to take command of the nation for its survival.

Assassination of King Zanac
Newly crowned King Zanac attempted to try at least one last time to sue for peace with the Sorcerer King. Going alone to meet them before their forces battled, he personally met with Ainz Ooal Gown. While he failed to convince the undead to call off his army, he did appeal to Ainz's human side and successfully made the enemy monarch rethink his course of action and possibly made him think of accepting their surrender instead. Knowing that he had failed, Zanac returned to his camp to meet his end with dignity on the battlefield. However several minor nobles desperate to survive, plotted and ambushed Zanac and his guards. Taking his head, they presented it to Ainz to become his vassals. Though they intended to appease the Sorcerer King with their "offering," their actions only ultimately fueled his motivations to burn what he saw was a corrupt nation to the ground in retaliation for King Zanac's death due to deeming that there was no longer anyone else worth saving within the corrupted nation and personally had the traitorous nobles tortured viciously together with their families for their betrayal of their own king.

Battle at the Re-Estize Plains
Disgusted by the nobles' betrayal and the assassination of Zanac, Ainz turns the conquest of the Kingdom into a large-scale massacre. The Royal Army are the first to feel his wrath and they are wiped out in an hour.

Eight Fingers' Evacuation Plan
Eight Fingers managed to bring a least a thousand people who were loyal to them to a newly constructed village to save them from the Sorcerer King's wrath; they also free Ampetif Cocco Doll so he can be of use to the Sorcerer Kingdom.

Albedo vs Azuth Aindra
At the start of the invasion of Re-Estize, the armies of the Sorcerer Kingdom marched to destroy the city. They were briefly attacked by an interloper who was none other than Azuth Aindra. The adventurer goaded Albedo to pursue him, knowing full well that he had no chance of victory. The main purpose of his attack was to draw the Sorcerer King's protection so that his ally Tsaindorcus Vaision could assassinate the former.

Ainz Ooal Gown vs Riku Aganeia
Tsaindorcus confronted the Sorcerer King. Their battle was intense and deadly but it came to an end once reinforcements arrived to aid Ainz and Tsaindorcus fled before he was overwhelmed. Despite failing to kill Ainz, Tsaindorcus was confident that he can defeat Ainz the next time they met after learning his full capabilities. Unbeknownst to the Dragon Lord, the "Ainz Ooal Gown" he has faced was actually Pandora's Actor in disguise.

Blue Roses Infighting
Lakyus Alvein Dale Aindra intended to remain in the capital and defend it to the bitter end. However, the same could not be said by her fellow comrades of Blue Roses. To escape the Kingdom's destruction, the group incapacitated and mind controlled their leader to force her to flee the city.

Siege of the Royal Capital
With all hope for the Kingdom gone following Tsaindorcus' failure, the Sorcerer Kingdom attacks the Royal Capital. The Kingdom's last remaining elite warriors, Brain Unglaus and Vesture Kloff Di Laufen, attempt to make a last stand. However, in the end, the capital fell with little resistance.

Fall of Ro Lente Castle
Third Princess Renner finally reveals her treason to the Kingdom by assassinating her own father, King Ramposa III. At the same time, the Sorcerer Kingdom besieges the Royal Palace and takes it in no time at all. Afterward, the former princess is welcomed to Nazarick as an honorary member.

Duel at Ro Lente Castle
With no-one else left, Princess Renner's bodyguard, Climb, is forced to face off against Sorcerer King Ainz Ooal Gown by himself. Unbeknownst to him, though, his "heroic last stand" was merely a set-up designed to allow his mistress to maintain her good standing in front of him post-defection.

Massacre at Domain Montserrat
To repay Philip, the man who in his vanity led to such a wasteful campaign of retaliation upon the Kingdom, the domain was visited by Albedo. Every single inhabitant from the nobles, their families, servants and villagers were impaled on the stakes. The only one to remain alive was Philip who was promised a slow death under extreme torture by the Prime Minister's hands after being requested by his own father to make his son pay for his foolishness.

Aftermath
The Re-Estize Kingdom was left in ruins with only a small handful of survivors who managed to stay alive either by escaping before its downfall or submitting to the rule of the Sorcerer King. The only monument left of the Kingdom was Ro Lente Castle which was left untouched whilst the entire royal capital was turned into a literal mountain of rubble and set ablaze by Guren to serve as a reminder to all of the consequences of going against the Sorcerer King and his kingdom.

Now that their fallen enemies' former territory was now the Sorcerer Kingdom's for the taking, they have done so with extreme swiftness. Pandora's Actor has successfully given false information about the Sorcerer King to Tsaindorcus Vaision during their duel. Renner is transformed into a demon and joined the ranks of Nazarick and manipulated Climb to do the same after his resurrection; adding the tactical genius and leadership skills of the former third princess Nazarick's collection of valuable assets. Nazarick claimed many useful items during their onslaught such as the legendary magic sword Razor Edge and the recently re-acquired prototype of Armageddon Evil.

The Fall of the Re-Estize Kingdom also caused the Sorcerer Kingdom's neighboring kingdoms to prepare themselves for what they believe to be an "inevitable" war with the Sorcerer Kingdom, as seen where Platinum Dragon Lord of the Argland Council State had attempted to assassinate the Sorcerer King and the Slane Theocracy had acquired additional manpower by assimilating some of the strongest and most talented Adventurers from the doomed Re-Estize Kingdom for their own military. Further hinting to their future diplomatic relationship with the Sorcerer Kingdom.

On the other hand, the Sorcerer Kingdom also gained the extra benefits of being able to successfully train the Floor Guardians of the Great Tomb of Nazarick in preparing massive and large scale invasions, waging war, and in strategy and conquest they can use for future wars and battles for the Sorcerer Kingdom. As seen where several of the Floor Guardians successfully conducted several experiments via trial and error to create various unique invasion strategies using their current resources. This was also the case with Shalltear Bloodfallen who had successfully created a highly effective invasion strategy that takes full advantage of her transport network of using their conquered Frost Dragons to air carry their Soul Eaters to bombard and annihilate entire cities and towns. Meanwhile, Mare Bello Fiore successfully gained experience on how to destroy large scale cities, residential areas and places of dwelling using his magic cleanly and effectively to massacre all of its inhabitants in mass. On the other hand, both Demiurge and Albedo obtained further political, espionage, and wide scale information manipulation experience for future operations. As for Cocytus, he obtained first hand experience on how to launch and lead a large scale invasion.
