First Battle of Carne Village was a conflict in which supposedly knights from the Baharuth Empire raided the frontier village of Carne.
Word reached the Royal Capital that a band of Imperial Knights were running wild in the vicinity of E-Rantel, laying waste to several villages. A response to these attacks was required by the Kingdom, to which the king sent the Warrior Troop led by Warrior Captain Gazef Stronoff, the only ones who could combat the knights. Unfortunately, only fifty members of the Warrior Troop could only be dispatched, as to not incite rumor of an imperial incursion at the insistence of the nobles. The Warrior Troop had to travel from the capital to the edges of the Kingdom's territory, allowing time for the knights from the Empire to pillage and slaughter a settlement before moving onto the next.
The Troop only found ruins of villages by the time they arrived in the region. Rather than retreat back to E-Rantel, Gazef who was furious at the destruction ordered his Vice Captain to assist the survivors and escort them safely to the fortress city. While it was obvious that the knights intentionally left survivors, so that the warriors would be obligated to assist them so as to divide the Troop's strength, Gazef insisted in going after them, understanding the weak villagers predicament and the need for those that attacked be brought to justice.
The last village that the knights attacked was a frontier settlement by the name of Carne Village. The inhabitants of the village who had lived near the forest had no fear of the monsters that dwelled within as their village laid near the territory of the Wise King of the Forest. Unfortunately, their dependence on the monster made the vulnerable to the knights who launched their attack on the unsuspecting villagers. The villagers were caught unprepared, many tried to flee but were struck by the swords of the knights.
Momonga who had been surveying the area surrounding the Great Tomb of Nazarick from his Mirror of Remote Viewing bore witnessed to the carnage. One scene in particular he witness a father struggle against a knight who attempted to rape his daughter, Enri Emmot. He managed to stall the knight giving Enri and her sister Nemu Emmot a chance to run into the forest. The man's deed was not without sacrifice as two knight appeared to pull him off Belius, who once freed from the commoner stabbed him with his sword. Collapsing from a fatal wound, the wayward player, Momonga watched as the man died, who to his shock looked straight at the Overlord, a feat that was deemed impossible through surveillance. Whether or not the man truly saw Momonga remains a mystery however the player read his dying words to save his daughter. Momonga initially did not wish to involve himself, however Sebas Tian who had also been watching mused the name of Touch Me, brought back memories of how his comrade saved him from being PK during his days as a beginner in YGGDRASIL. He then prepared to leave to engage the knight, ordering the butler to inform Albedo and to have her fully equipped.
Meanwhile, Enri and Nemu were fleeing for their lives as two knight pursued them. Nemu unfortunately stumbled and fell, allowing on of the knights to catch up. Putting herself between her and the approaching knight, Enri managed to land a punch at the knight's helmet momentarily stunning him. The knight recovered, swiping his sword across her back. Enri injured kept Nemu close and prepared to die as the knight's sword loomed above. Just as the sword fell, Ainz appeared from his [Gate] directly behind the cowering girls. The knight shocked at the appearance of the undead halted his attack on his targets. Taking the advantage, Momonga casted [Grasp Heart], the death spell killing the knight instantly.
Just as the sword fell, Ainz appeared from his [Gate] directly behind the cowering girls. The knight shocked at the appearance of the undead halted his attack on his targets. Taking the advantage, Momonga casted [Grasp Heart], the death spell killing the knight instantly. Momonga seeing his indifference to the death of the knight to be a peculiar side-effect from his racial form turned his attention on the second knight who backed away in fear at Momonga. Wanting to test his abilities further, Momonga casted [Dragon Lightning] upon the knight as he tried to flee. The knight's death disappointed him, as the spell was considered weak 5th Tier Magic. Confirming that the knights were far too weak to be considered a threat, Momonga casted [Creat Mid Tier Undead, Death Knight] in order to test his abilities. To his shock rather than a normal summon, the Death Knight was formed from the corpse of the knight he killed. Taking it to note he ordered the undead to slay all the knights in the village.
Heeding its orders the Death Knight quickly rushes to the village. Momonga is left surprised at the summon's independence but is quickly interrupted by the arrival of Albedo who is armed in her Hermes Trismegistus. Seeing the two human girls, Albedo asks what is to be done with them. When she suggests that they be killed, Momonga rejects it stating his intention is to save the village. Turning his attention to the girls he gives Enri Emmot a Minor Healing Potion. Though he tells her to drink it, Nemu prevents her from, believing it to be poison. It was only at Albedo's and Momonga's threats does the girl finally drink it to which instantly heals the wound on her back. Satisfied, Ainz casts multiple spells on the girls to protect them an in addition gives Enri two pieces of Horn of the Goblin General. Before departing, Enri and Nemu kneel thanking Momonga for saving them and request his name. Momonga responded in reflex declaring himself Ainz Ooal Gown.
Back at Carne Village, the knights had gathered sixty of the surviving villagers in the village square. In addition several children are hiding behind a wooden watchtower. The knights intended to massacre the villagers to use them as bait against Gazef, however before they could do so, the Death Knight appeared. It attacked a knight bashing him with its tower shield flinging him into the air. Next it attacked a knight that attempted to flee, bisecting him. The knights tried to attack, but the undead's defense couldn't strike a dealing blow. In contrast the Death Knight was content to bash the knights, only dealing fatal blows unless one of them tried to escape. The fearsome knights that had terrorized the village were helpless against the creature. Belius, the captain of the knight squad, completely broke down, demanding his subordinates to hold the monster off as he tried to escape. Hearing his constant pleas to use them as human shields, none of the knights stepped forward to comply. The deranged captain then began bargaining with his men, offering compensation. His tirade went on until the bisected half of one of the knight grip his leg, causing him to scream and fall over the zombie. The Death Knight singling him out, plunging its flamberge into his chest as the man pathetically begged and called for help.
The knights are brought back to order at the voice of Londes Di Clamp who orders the remaining knights to kill behead the bodies of the corpses slain and to hold out until their riders come with reinforcements at the sound of the horn. Londes engages the knight one on one, only to have the Death Knight behead him.
The newly christen Ainz Ooal Gown continues his journey to the village with Albedo. Flying above they declare their presence and his name. Now wearing the Mask of Envy and Járngreipr to disguise himself of his appearance, Ainz orders the Death Knight to halt its attack. He gives his demands to the knights; if they throw down their weapons he would guarantee their safety. Immediately the knights cast down their arms and alter prostate themselves before the Overlord at his suggestion. Ainz satisfied at the submission orders them to leave and tell their owner not to cause trouble in this region less he will bring ruin to their country.
The knights run for their lives, as Ainz watches them he orders the Death Knight to clean up its zombies. Turning his attention to the villagers. The villager asks who he is and he states he is merely one who saw the knight attacking and decided to help. Their unease does not completely disappear despite his word that he is a friend. Thus he chooses a need tactic in demanding a reward for his services to allay their suspicions of his intentions.
Ainz later meets with the Chief of Carne Village, who is grateful for the man's aid in saving his people. Sadly the man is unable to pay Ainz a suitable amount. Understanding this, Ainz instead accepts information, explaining that he is a sequestered magic caster and wishes to know about the surrounding lands. From his conversation with the chief and his wife, he gains knowledge of the Re-Estize Kingdom which the village belongs to, the Baharuth Empire and the Slane Theocracy. Thinking about the knights Ainz suspects that they were actually from the Theocracy posing as knights from the Empire. Despite knowing this he keeps it to himself. He further gains a rough generalization of the New World and what perked his interest is the Adventurer's Guild. The village cleans up in the aftermath of the attack by the knight, Ainz watches the burial of the dead. While possessing a Resurrection Wand, he declines to use it as it wouldn't be beneficial to him. Albedo is eager to leave the area having detest the presence of the humans, Ainz agrees that they have overstay but before they could leave the chief informs the two that men on horseback heading towards the village.
Gazef Stronoff and several members of the Warrior Troop arrived to render their aid to the village. Gazef learns from the chief that Ainz Ooal Gown saved the village from the marauding knights. The Warror Captain thanks the magic caster despite Ainz honestly stating he did it for money. They two engage in a friendly dialogue until one of the warriors report that the village had been surrounded by an armed force magic caster and their summons.
