Overlord and the Seraphim

『The Months After Transition』

Three Months had gone by since their arrival and the name of Momon and Nabe along with the Swords of Darkness could be heard all the way in the Empire itself. Ainz's exploits as Momon were immeasurable as an Adventurer. The slaying of giant beasts that took even other Adamantite Adventurer's a long time to slay, in mere seconds. This legendary hero was responsible for entire annihilations of the bandit and mercenary camps which caused chaos within the borders of the Kingdom. So Within the first Month of their transition, the Lizard people around the Lake in the Great Forest of Tob under the dominion of Nazarick, it was ever more clear even the beastmen communities were not safe from their domineering influence. 

Demiurge and a small strike force were sent to the remaining settlements in the Slaine Theocracy, claiming to be a follower to the renewed incarnations of their Gods of Life and Death.

At first, no one caught onto it, while others believed it was Surshana who had visited the Capital and laid it to waste. They brought death to the centralized command of their Theocracy.

With subtle manipulations, he used the humanoid homunculi as the Priestesses and lead them to what they believed was salvation. Elves were separated from humans, not to be returned to the Elf Kingdom, but to be settled on the Sixth Floor of the Great Tomb. 

Under the supervision of the Dark Elf Twins, they began their indoctrination under the Orders of their supreme Leader Ainz Ooal Gown. Thanks to information about the Elven King, Ainz planned on using the twins as the future rulers of the Elf Kingdom as to subvert possible revolt.

The humans from the Slaine Theocracy, however, were to be screen extensively. Racist, extremist and possible future anti-Nazarick sentiments were not allowed to stand.

Ainz Ooal Gown took this opportunity to extensively test the use of Control Amnesia to learn techniques in order to manipulate the minds of others. Changing, altering or completely erasing memories, he found easily that the human mind was fragile.

Some of the test subjects did not respond well, some of them losing the ability to talk and others going into complete vegetable states.

Following his own personal thoughts towards what is right and wrong, children were excluded from the experiments. However, after several periods of testing on their adult counterparts, their memories of their parents were erased and their adolescent ideologies were indoctrinated to fit his agenda.

After the Empire pushed out of the Slaine Theocracy Territory by an unknown force of masked beings, Ainz Ooal Gown discretely flooded its borders with his undead armies. These armies consisted of armored skeletons made from bandits, mercenaries, and criminals alike. 

Not too long afterward, it became very apparent it wasn't an occupying force. It was a force centered on the extermination of Slaine Theocracy government holdouts, with a secondary mission. Locate and obtain items that may have come from YGGDRASIL, such as World Items.

Those who remained in the territory were forced either into the Beastman Enclave territory or towards E-Rantel. Monsters awaited them in the Enclave territory, and soldiers waited for them at the Southern Border of the Kingdom.

There was no escape on either front. They played cat and mouse for the first two months, hiding in ruins and abandoned villages. Walled towns that were still occupied kept their gates sealed.

No one wanted to leave, it wasn't safe outside. However, this did not stop the undead from toppling these walled cities and towns overnight. The powerful high-end magic scrolls made from parchment composed of human flesh and precious resources, their armored doors didn't hold against invasion.

With their scriptures out of order, there being no central high command, the Theocracy continued to collapse. Panic, hysteria and further xenophobia was the only thing they knew.
