One day in X776, within a large tower where a number of people that being kept as slaves by Tower of Heaven Cult working bring back the black wizard Zeref. One of the slaves named Sho came up with a plan for their friends to escape from the tower. They were unfortunately caught by the guards, who decided to send the escape's mastermind to the tower's disciplinary chamber, while the rest would be deprived of food for three days. Seeing how fearful Shô was, one of his friends a red hair eleven year old named Erza prepared to take the blame herself, but another of Sho's friends, Jellal, announced himself as the mastermind instead.

However, the guards reasoned that Erza was the one responsible and sent her to the disciplinary chamber, where she lost her right eye as she was tortured to death. However just as her lifeless body was about to toss that when one of the cult members want it for themselves. Claiming they had something they wanted to test out and this body could prove useful in their experiment. The durability of Erza's body was amazing and might actually be able to withstand the process of their experiment.

The experiment was an attempt at bringing someone back life as a zombie. The idea they had was that living slave were too much of a problem. For they needed to eat, sleep, and got tired. Then there were chances of them revolting on them as well. So this cult member thought a zombie would be much better slaves but could not perfect the process by having a successful test subject so far.

The experiment was finally had a success as the cult member was able to reanimate Erza's body bring her back as a zombie. All the various injuries that Erza had gotten both before and after her death were were repaired through the magic of the ritual that brought her back to life. However she just mindless zombie girl that would only follow orders and need eat lacrima to remain animated but also heal from what injuries she sustained. When she did not have enough lacrima she would stop moving until enough was given to her to move again.

Sometime later...

"Do you know why we gathered here today?" a Dark Mage asked

Members of the Tower of Heaven Cult were originally just a bunch of Dark Mages that worshiped the Black Arts and wished to bring Zeref, viewed as the greatest user of the Black Arts, back to life. The name of their cult was unofficial and just something that many of the members called themselves. After all the Tower of Heaven was the device they were having the slaves work on.

"Who knows as I do not even know why we are wasting our time with this mage's research. When we should focus our effort and resources on the building of this tower" another Dark Mage stated.

The Dark Mages that were interested into the Black Arts had gather many liked minded individuals and resources in trying to create eight Tower of Heavens. However, of the eight they were trying to build this was the only one that had not been discovered by the Mage Council and thus their last hope. Members that managed to escape being captured flocked here to the eighth tower. The original plan was the use eight towers to lower the cost need to bring someone back to life. However, now that only one tower was left they would just have to make do with this one alone.

The Mage that called them here today was from one of the towers that had been shutdown. They claimed their research would help them in boosting productivity and reduce revolts and/or escape attempts. However, there attempts at doing so at the moment had all ended in failure as many were thinking they just making easier to dispose of the dead body of slaves that been used up and outlived their purpose.

The Dark Mage in question named Koyama walked in with a smug look on his face as looked over the other members of the cult.

"Prepare to be amazed" Koyama stated as then stood aside and ordered Erza to come forward.

The look on her face was expressionless as stood there with a dull vacant eye starting start ahead at nothing. Though all the injuries from being tortured to death were healed from bring brought back to life. The one only that did was her missing eye. Which she now had an eye patch covering it up.

"What this suppose to be as this merely the…." the cult member said but then caught themselves as they realized what was going on here.

"That's right as I have succeeded in bringing someone back life as I merely need body strong enough to withstand the process" Koyama informed them.

The members were amazed as they checked Erza over to ensure that she was truly a dead body brought back to life. Sure enough, they heard no heartbeat and her skin was cold to the touch as her body held no warmth to it.

"That is not all as now that this girl is a zombie. The limiters that the brain imposes on the body are no more as she can use 100% of her strength and whatever damage that cause to her body is automatically repaired thank to the system keeping her animated" he told "and her is the best part as apparently this girl had dormant magical abilities that are now awaken after her death"

"What kind of magical ability could a…" a mage tried question Koyama but found various weapons floating in air staring them in the face

At this, the others found Erza as a very interesting tool that they could use and hopefully reproduce with others. Even if they could just having her at the moment and the ability to control weapons could be various useful the progress of the completing the tower.

Later that day the slaves were gather up and told there were be a new announcement. Gathering like this were never really a good thing so many were preparing for the worse. The only hope that many of them had was that they would be able to see the next day or that they would not be worked either harder for the failed escape plan that happened.

Koyama appeared before them all with look the slaves were all used to getting from their capturers but some noticed a difference in this mage. That they looked at them over them with a eye as if they were not even slave anymore but something even worse.

"As you all are probably aware there was a escape attempt recently and the person that was behind it has been dealt with punishment that was fitting for their disobedience against us" he stated.

At this Erza's friends and others she knew started to pay more attention. Jellal and Sho wanted to stage a rescue for Erza himself but he was talked out of it by Rob. Claiming that the time was not right for them to attempt a rescue as they had no information on what was happening to Erza. Though he understood the desire to do something to help but going in without a plan was not just too reckless. They did not have enough people to counter the guards and then there were others that could betray them to the guards as well. While many might have been willingly to follow them there were those that had lose hope after the last failed attempt thus might be so eager to try again so quickly.

"They were killed through being tortured" Koyama declared

Things got so quite that it was possible to heard a pin drop so that made the footsteps they all heard coming towards them. At first it seem like they were a member of the cult as they were dressed as such. However what drew attention was their size as they were far shorter then most of the other known members.

Standing before them they removed the mask that had the Tower of Heaven Cult's symbol from their face. Causing utter shock to ring out through the crowd of slaves. There stood Erza the one that Koyama had just claimed was dead standing before them seemingly as member of their cult now.

Though they noticed something very different about her as she merely stood there with lifeless expression on her face and vacant look in her eye she still seemingly had.

"This girl is no longer alive as she is in fact dead. However I managed to bring her back to life where she will now serve us as loyal tool and weapon for our cult's goal. Now not even death will not allow you to escape from us, as you will be brought back to life and forced to serve us" Koyama declared.

Jellal and Sho were about to rush Koyama right then and there for what they had done to Erza but were against stopped this time by Rob and Simon. It was good thing that the two of them managed to do as others were not so lucky to have themselves stopped. They rushed at the Koyama only to impaled by number of weapons that were directed towards them. Weapons they saw were being controlled by Erza.

Rob would later on explain that why he did so. He was aware of Erza's true magic potential and was grateful that Koyama and the other Cult members were not aware of the true depth of it. Merely sticking with her ability to control weapons. Though that did not make things any easier but at least they were not as bad as they could have been. Rob informed Jellal and the others what he thought Erza's magic truly was and despite being activate. In her current state, Erza would not be able to use it if not order to do so.

The plan now became how to go about helping Erza if possible and if not then finding a way to undo spell that was animating her body.
