Battle of E-Naeurl

Battle of E-Naüru was a battle in the war between the Re-Estize Kingdom and the Sorcerer Kingdom. It was the first major battle of the conflict.

Background
After the Re-Estize Kingdom's New Faction attacked one of their transports, the Sorcerer Kingdom declared war on the nation and stated they would invade in one month.

In response, despite knowing they did not stand a chance, the Kingdom began preparing for war. However, this only applied for territories who were likely to be within the armies' path. On the other hand, regions that would likely only be effected by the time the Royal Capital had already fallen did not even bother to evacuate the civilians or build fortifications.

However, unbeknownst to the Kingdom, the date the Sorcerer Kingdom had given for the start of their invasion was an elaborate ruse. While the Kingdom prepared, the Sorcerer Kingdom secretly marched their armies over the border and began invading those territories that thought themselves to be outside the line of fire. Like this, the Sorcerer Kingdom easily conquered the Kingdom's western and northern regions, cutting the nation off from its last remaining ally, the Argland Council State, and isolating the Royal Capital. Then, they massacred all the inhabitants and halted the flow of information out of these regions, causing the Kingdom's leadership to have no idea that the Sorcerer Kingdom had already begun their invasion.

To complete their encirclement, the Sorcerer Kingdom targeted the port city of E-Naüru. Before this however, news of the invasion had finally leaked out, when a noble escaped his territory just before the Sorcerer Kingdom attacked and made it to the port. Now knowing they were coming, the city began last-minute preparations. The city's overseer, Count Naüa, called on multiple organizations for aid. A special Magic Caster Unit was formed and the city's strongest Adventurer group, Four Armaments, was put in charge of the defenses. An evacuation order was also given, though most citizens had nowhere to go and thus choose to stay.

Before the Sorcerer Kingdom attacked, however, Ainz was confronted by Nazarick's human sympathizers, who pleaded with him to stop the slaughter of innocent civilians. Thus, to appease them, the Sorcerer King intended to spare a few humans by losing this battle on purpose. He therefore only sent an army of low-ranking Undead to give the citizens of E-Naüru a fighting chance.

Battle
E-Naüru's defenders saw that the Sorcerer Kingdom's forces were mostly low-ranking Undead. Two stuck out though: a Death Knight and Death Warrior. Since both them were close-quarter combatants, Four Armaments decided that the best strategy was a long-range battle. However, arrows were unlikely to do much to the Death Knight and Warrior. This meant they would eventually have to engage them in close-quarters, in which case, the amount of damage they could inflict before they penetrated the city would decide the battle.

Once the undead were within range, archers began to loosen their arrows on them and actually managed to take out a fair bit. After just three volleys, however, the Death Knight suddenly began rushing towards the city gate. In response, the leader of Four Armaments, Scama Elbero, ordered magic caster to use [Fireball] on it. Despite hitting it at point black range, however, the Death Knight didn't seem to have taken any damage and pressed on. Even though they continued hitting it with [Fireballs], the Death Knight didn't even slow down and eventually reached the city gate, where the magic caster couldn't aim at it due to a bad angle.

As the Death Knight began ramming the city gate, Scama ordered the city defenders to direct their attention to it and the Death Warrior. In order to get the Death Knight back into the magic casters' line-of-sight, Scama, Lilynette Piani and her Four Armaments' magic caster faced the undead. However, not wanting to face such a powerful foe directly, they tried to fight it from a distance using the [Lighting] spell. Unfortunately, their attacks proved ineffective and the gate eventually gave way.

As the Death Knight entered the city, Scama prepared to face it in direct combat. However, despite her teammates and the city magic caster supporting her with buffs and spells, she quickly found herself on the defensive. Despite this though, she had to continue fighting the Death Knight lest it swift it's attention to the city, which would most likely result in mass civilian casualties. Scama attempted to lure the Death Knight to the city walls, where the magic caster would have a better shot at it, when wails could be heard that the Undead army was closing in.

While the city defenders fought the approaching undead, Four Armaments continued their battle with the Death Knight. However, their attempts to harm and restrain it continued to prove ineffective and it was eventually joined by the arrival of the Death Knight. Seeing the situation as hopeless, Scama ordered her teammates to run. However, just then, the Death Knight's head was pierced by a bullet from the sky.

Looking up the city defenders and remaining Undead spotted a flying armored giant with a gun. Quickly concluding it was their ally, Four Armaments moved away as the Death Warrior threw one of it's swords at it. However, the armored giant just tanked the damage and then unloaded it's gun on the Death Warrior, killing it.

Four Armaments concluded from the Adamantite metal around the armored giant's neck that it must be a member of Red Drop. The floating armor then signaled the Adventurer Group goodbye and flew away. It was unknown what became of the remaining undead. However, with the defeat of the Death Knight and Warrior, they were presumably defeated soon after.

Aftermath
The citizens of E-Naüru hoped Red Drop would continue to participate in battles henceforth. They also believed that the Sorcerer Kingdom's invasion would soon end with this unexpected victory.

The Sorcerer Kingdom learned of the loss almost immediately, due to Ainz Ooal Gown sensing the destruction of the Death Knight and Warrior. Fortunately, the Sorcerer King did not face any consequences for the loss, as the Floor Guardians believed the reason why he send such a meager force was to draw out Red Drop.
