It was night and the moon was full that was shining upon the Great Forest of Tob. Near the forest, a skeleton was walking. Naturally, there were bones below. A dark red orb floated under his ribs, emanating a feeling of dread. He was just wearing pants and boots, on his right skeletal hand, he was holding a black sword.
This skeleton was Ainz himself, the wind blew between his bones. While walking, he stopped and the reason why was because a thick tree was in front of him. He saw the large tree and the red points inside his skull glow like fire.
"BEGONE!"
With a slash, he cut the tree with his black sword. The thick tree fly 10 meters away. If any mortal would have seen this, they would have been shocked. Even for a dragon would have not been easy to do something like that, yet Ainz did it like it was nothing.
Ainz sit on the tree trunk, he stuck his black sword to the ground and turned his skull to the full moon that was giving light to his clean white bones.
"Man, what the hell should I do?"
Ever since he left the capital, this question was stuck in his mind. Ainz wanted to slaughter all those nobles that insulted him...Him, the World Class Enemy that can send the entire kingdom into oblivion with a blink of an eye. But was it worth doing that. Right now he had followed the steps of his friend Touch Me, being a hero that saves those in need and danger and that was what lead him in this state. So what should he do now?
Travel to the Empire? That nation must be like the Kingdom, that's what Ainz thought.
Ainz was lost deep in thoughts. There were some other alternatives but he didn't prefer those.
"So what should I do, hmm?"
He was thinking and thinking and suddenly the words of a great friend showed up in is minde.
"Let's conquer one of the nine worlds."
"Huh?"
Ainz remembered the words of the Demon of Great Disaster, Ulbert Alain Odle.
After the Holy Alliance failed to conquer The Great Tomb of Nazarick, Ainz Ooal Gown prepared for revenge. They gathered all their allies that belonged to the heteromorphic race. Guilds that belonged to the undead race, demonic race, dragonid race and other monstrosities, all answered Ainz Ooal Gown call. They all gathered inside a large cave in Helheim and discussed about the destruction of the Holy Alliance. The members of Ainz Ooal Gown asked about forming a grand alliance against the strongest guilds like Seraphim or Trinity and put an end to the discrimination. They all accepted this without question because this war will bring great spoils.
Touch Me suggested to call this union the Justice Alliance but to everyone that sounded kind of cringe even to Momonga. They were the villains, so they must have an evil title. The demon of catastrophe, Ulbert Alain Odle suggested to call this alliance The Heteromorphic Empire. This puts a smile on everyone's faces, that name sounded cool and evil, perfectly for villains, everyone accepted this but the Empire will need an Emperor so the members of Ainz Ooal Gown suggested Momonga to become the Emperor of the Heteromorphic Empire.
A demonic guild suggested to put a demon as an Emperor because it will be very cool but the other guild didn't accept that because an Overlord Emperor was more badass and with this the Heteromorphic Empire was formed.
They didn't attack the Holy Alliance yet, no that will be to hasty. The Heteromorphic Empire started to invade the world of Helheim, every humanoid guild was destroyed in an instant by the imperial army and every player that traveled to the world of Helheim was PKed by the members of the Heteromorphic Empire, the humanoids weren't the hunters anymore, they now were the prey. After putting the world of Helheim in their hands, the Heteromorphic Empire was preparing to launch an attack on the world of Asgard where the guild of Seraphim and Trinity was located.
First they unleashed their undead, demonic, draconic armies to destroy the villages and cities that were protected by the Seraphim and Trinity. That lured out the humanoid and angelic players and a terrifying battle started that was never seen before in the history of YGGDRASIL.
On by one, the members of the Holy Alliance were destroyed by the powerful members of the Heteromorphic Empire till they reached the heart of the Holy Alliance. The Kingdom of Heaven that was the base of Seraphim was attacked by a large army that was led by the undead emperor Momonga, Touch Me, Ulbert Alain Odle and other allies. Their golden walls fell when they were hit by the powerful magic of the magic casters. Their NPCs were defeated by the NPCs of the Empire and floor after floor was destroyed till they reached the angelic throne. The members of Seraphim fought well but against a World Champion, World Disaster and a World Class Enemy they had no chances. When the guildmaster of Seraphim that was a female fell, the undead emperor Momonga destroyed the guild weapon and with this, the age of Seraphim was over.
Trinity had the same fate as the other guilds that were allies of the Holy Alliance. Nobody could dare to fight against the Heteromorphic Empire now and with that, the world of Asgard became a territory of the Empire.
This was the golden age for Ainz Ooal Gown and their allies, memories that Ainz will never forget.
"World conquest, huh Ulbert? That sounds really interesting, kukuku!" Ainz chuckled like an evil mastermind.
"Touch Me, being hero like you wanted sucks, now I have to follow the instructions of Ulbert."
Since he became an adventurer, he was Suzuki Satoru, a hero that protected the weak. But now he has to kill him and become Ainz Ooal Gown, the Overlord.
"These people need someone powerful that will stop all the bullshit that is happening in this kingdom. They will not like me because I am an undead, but when I make their lives better, I think they will change, just like the villagers of Carne."
Humans exist in this world and Ainz didn't want them to create advanced technology and pollut this world like the humans did with Earth.
"No… I will never allow them to reach that damn teknology!"
Ainz wanted this world to be always a beautiful medieval fantasy that all races live together in harmony under the rule of an immortal king but to achieve this, he needs to create a grand army and powerful subordinates that will protect his kingdom. Humans were corrupted beings, demihumans were not disciplined. He's only choice was an undead army. The undead that are created by Ainz himself are loyal, disciplined and really powerful, an ideal army.
But how can he create a large army? He can't just go to villages and massacre humans to turn them into undead. The humans will give him a bad title like the Eight Greed Kings, so how can he achieve this?
Katze Plains
That was a cursed land that is surrounded by a permanent foggy atmosphere that spawns undead every day.
"Oh yeah, that lande that the kingdom and the empire fight every year. Yup, that will be a perfect place that nobody will disturb me while I create my army. Oh yeah. It's all coming together, kukuku."
Ainz was excited about this. But it will take years to create a large army of Death Knights. Ainz can summon 160 Death Knights per day so that means, if he summon 160 Death Knights every day, in one year there will be 58,400 Death Knights.
"Ah, but that's not enough, I need more. How many years, I need to create an army of 400.000 Death Knights, hmmm, six or seven years I think. Oh, hold one a second, I can summon high level undead that can summon twelve Death Knights per day, kuku.
The level 100 undead that Ainz can summon are Grim Reaper Thanatos, Overlord Wiseman, Undead Lieutenant, Overlord General, Witch King, Death Emperor and many other level 80-85 and 90-95 powerful undead. The high level vampires that he can summon were only level 85-90.
There was only one level 100 demon that Ainz can summon and that will be a Succubus. Ainz has a class called Dark Bishop that allow him to summon a level 95 Seraph and a level 100 Seraph Empyrean.
"An undead will stay permanent if I use a corpse, but how does it work with demons and angels...Do I have to make a sacrifice like killing a virgin women or some other shit? Im acting like Tabula right now. Hmm, I will think about angels and demons later. Come to think of it, I have a trump card."
With a dark ritual, Ainz can summon a large undead army per day like he did in the 3rd floor of The Great Tomb of Nazarick. He wanted to have Death Knights as pop monsters in Nazarick but it didn't work with he's dark ritual, so he spent real money and used some cash items to summon on thousand Death Knights.
"Evileye said that, when many undead are gathered in one place, a powerful undead will be born. So that means, I will gather thousands of undead or even millions if it is possible and use my dark ritual to summon at last three thousand level 30 undead or I hope level 35-40 Death Warriors, that will be absolutely perfect."
If he can do this, Ainz will have an army of millions. He wanted to build his kingdom like a guild. Level 100 servants will protect the territories of his kingdom like a floor guardian would do.
"Shit, why didn't I think about this before… Wait a minute, it's not like I had information when I arrived to this world. Ah, whatever, I need to go to Katze Plains now and start to rise my army, fufu. Can't wait to see those noble scumbags in despair and I will make sure that...hmm… what is that?
There was something that came out of the forest and it was coming to Ainz direction. It was really fast for a human but what Ainz saw strange was that the person was not looking in the direction that it was running, but it was looking behind, like something is chasing it.
Oi, it's not looking at this way at all, what the…"
It didn't pass much and it came right to Ainz and with a "bam" it made an impact with his skeletal body. It rose it's head while rubbing it and saw in the direction of Ainz. It's eyes from worried turned to horrified.
Ainz observed its body and it was…
"A women…"
