Unzombification Experiment

Unzombification Experiment is a form of experimentation conducted by Suzuki Satoru and Keno Fasris Invern.

Objective
The goal of this experiment was to undo the zombification state of Keno's countrymen of Inveria including her parents. This includes needing to remove their undead status.

Once this was over, they switch their sight to finding the one responsible for the zombification and killing whoever that done it as their second experiment. The two share the notion that if they were to put an end to the culprit's life, somehow every undead zombie mindlessly roaming Inveria will change back to the living.

Procedures
Within the castle of Inveria, Keno guided Suzuki to a place where there is a suitable candidate for using Lost White to cast revival magic on. Seeing that the zombie guard is quite strong in life prior to it becoming an undead for their resurrection to succeed, Suzuki decides to capture it for the sake of their experiment. Suzuki opens up a [Gate] spell and transported himself, Keno, and the zombie outside the city through it. Taking precaution measure, Suzuki already made sure to grab part of the guard’s armor in order to make certain that it could not be interpreted as a hostile attack, before then dragging him into the [Gate].

Upon arriving outside the castle, Suzuki swiftly killed the zombie in one blow, lopping off its head off with a magically-conjured sword. Afterwards, he allows Keno to proceed on utilizing her magic wand to cast the 5th-tier spell, [Raise Dead] on the corpse of the slain zombie.

Later, they went on a five-year journey, leaving Inveria to go on a search for various intel of events and places like Aina Miscegenation League and Mount Keitenias that are closely connected to the fall of Keno's country. The two had even visited a Large Walled City and hired Mercenary Pathfinders to do some intelligence gathering for them in their stead. Eventually, they deduced and find out that Elder Coffin Dragon Lord, Cure Elim Los Malvar is primarily held responsibility for the zombification phenomena that happen to the people of Inveria. Suzuki decided to engage it in combat alone and killed the said Dragon Lord.

Results
During their first experiment, the pure white light within the wand moved to the corpse of the zombie guard. The corpse slowly got to its feet, but that was not a sign that it had returned to life. It was simply a Zombie moving once more. In other words, although resurrection magic proves to be a success in bringing the guard back, it did not in anyway shape or form return/revert the zombie back to being part of the living.

On the other hand, for this second experiment, the death of the culprit Cure Elim proves unsuccessful on eliminating the undead status of Keno's people in Inveria. Despite Cure Elim having been killed by Suzuki, Keno's people continued acting, moving and remaining as the same mindless zombie as they always were since becoming an undead. This also concludes that even if the zombie controller Cure Elim is no longer alive, the zombies will not die or disappear with him.

Trivia

 * Two hundred years later, Keno lost her hopes and interests in attempting to find a way on undoing the zombification phenomena on the people of Inveria.
 * In the main timeline and setting, Gustav shows concern about the Sorcerer Kingdom's undead. Gustav ponders that if the Sorcerer King Ainz Ooal Gown, who controls so many undead, is destroyed, the latter's death will free the undead from its control. Seeing the worst-case scenario, he believes that without Ainz alive to keep the Sorcerer Kingdom's undead in check, they will only cause an incredible amount of havoc.
