Ok, before anyone starts to read, I have a couple of things to say.

First of all, for those who don't follow the manga, please do not read this fanfiction, since it's has spoilers. And for those who follow it, I'm really sorry for taking Reiner, Bertholdt, Ymir, Christa and Pastor Nick already out of the story, but since I decided to write this in a time to which the manga hadn't reached yet, I left them out because nobody knows what is really going to happen, and since the manga is still ongoing, I took off those characters who are currently into the main plot. Sorry, but in order to create a plot 'of my own', so to speak, I really needed to.

Another thing I wanted to say is that I'm not a native speaker of English but an 'English as a second language' student, so if you catch some grammar mistakes or weird vocabulary usage during your reading, I apologize for that and please ask you for letting me know about it to correct it. However, in order to improve vocabulary and the amount of different words I'll be using, I thought of a game. Yes, a game. It'd be easy, a piece of cake, actually.

I thought that after you read, you may want to leave a review, right? So, every time you do so, I ask you to leave a word for me. Any word that you'd like me to incorporate into the text, especially if it's an adjective or a verb that you think fits to a character's personality or to a situation you'd like to read. So, after your reviews, I'll study the semantic meaning of every word and analyze how and when to use it.

[EDIT: As of October 4th, 2016, I am back working on this, so expect an update soon.]

FIRST PART
Darkness

Chapter 1
Blind

Four months had passed since they could finally kill Reiner and Bertholdt, though they still couldn't get Annie off of her crystal shield or whatever that it was, an issue that was driving Hanji crazy. They also didn't know where Ymir and Christa were. Even Pastor Nick had disappeared. Hence, many soldiers from the Scouting Legion were starting to freak out.

They were scared, driven by doubt and insecurity. What would happen now? It was during those times of people's insecurity when Erwin proved to be a good leader, encouraging people to continue working hard, especially to those soldiers from the 104th trainee squad who were eager to fight under the hope of recovering Wall Maria with Eren's help. And as they were close to fulfilling that dream, the more enthusiastic and stronger they got.

Erwin had managed to bring success to the Scouting Legion with little victories. First, he planned to establish a new route from each district of Wall Rose to their respective near districts in Wall Maria. The goal was to divide the Scouting Legion into three teams and get them to Wall Maria as quickly as possible at the same time in one extramural expedition, and so they did.

Then the idea was to establish themselves in the three abandoned cities of Wall Maria that still had their doors closed, which meant they weren't invaded by titans. They could perfectly do that. For the next step, they just had to gather as much supplies as they could get from the three cities and work hard to get them up into the wall and transport them towards Shiganshina. That took them about two more weeks.

As for what was next, they had started to carry out the next step, which was filling the hole in the wall, for which Eren was crucial. He had to quickly gather as much supplies as he could in his titan form and build -during the afternoon- the first provisional wall that would stop the titans from coming into the whereabouts of Wall Maria, while the soldiers would protect him and his task from any danger. Then, during the night, everybody would clean the cannons while Eren would rest.

On the second day of building, everyone had to protect Eren's titan form again from the titans that were inside between Rose and Maria while he would build a second provisional wall. Just to be sure that the titans wouldn't break the first one so easily.

Until then, Corporal Levi was doing an outstanding work killing titans, but as he was still human, he couldn't control the whole situation by himself and, in the blink of an eye, an eccentric titan broke the defense line and bit Eren's right leg. It was not more than a 6-meter titan, but still, that was a mistake Levi couldn't stand, so he killed it right away. He almost went out of gas doing so.

"Eren, are you alright?" Levi screamed to him, since he was now on the floor, and as soon as Eren nodded, he talked to him again. "Lift me up. I'm almost out of gas now." Eren put his hand beside him, Levi climbed and Eren threw him up the wall. Levi flew up almost forty meters and used the gas left to climb to the top. Then he quickly changed his gas supply and went back to work.

Since Petra and the other members of Levi's unit died, they both had to learn how to work as a team since they were all the team had left. Erwin had suggested Levi to take Mikasa and Armin into the squad too, so then Eren would be even more protected. Levi didn't seem happy with that suggestion, but instead of having refusing it instantly, he took a moment to think about it. He would definitely not take Armin into his squad. That was something he considered completely pointless and stupid, not only because he was weak, but also because he would fit better in any other squad where he had to think instead to kill. On the other hand, Mikasa was worth recruiting.

After several days considering it, he talked to Eren about it as he usually would regarding squad matters, and two days later he received a negative answer. Eren had mentioned it to her and she had completely refused the idea. "I won't join that asshole's squad even if I was paid for", she had proudly said. After that, the team remained of only two.

However, some days later, Eren had spoken to him again about it. "Mikasa asked to me today if she could still join our squad... I guess she got really scared with the last expedition." Of course she got scared. Eren had reached his titan form's limit far away from getting to Rose and was dangerously surrounded by titans. If it weren't for Levi that saved him, he would have been eaten.

Levi didn't take that very good, so his answer was rude, very rude. "Since when does she believe I'm that good of a person? Fuck her. I won't accept scared and proud cry-babies into my team. " The team remained of two until that day.

Levi had gone for another gas supply when more titans approached to Eren and heard Mikasa screaming. For a moment or two, he felt really worried and tired, but quickly grabbed new blades to return to battle. Then he realized that Eren had finished building the provisional wall, just in time before some titans jumped in to bite him, and the reason Mikasa was screaming was because Eren was surrounded –just as so many times before– by titans while she was trying to kill them.

Instead of helping with the killing, Levi went just straight to Eren's titan form's neck and cut it to take him out. He pulled of one of Eren's arms and, once out, he carried him on his shoulder, half unconscious. He was in his way to climb the wall when a titan jumped at them. He could see their death coming, but Hanji and Mikasa cut the titan's head before he could do some chewing with them.

They got completely covered in blood with that, which made him sick for a second or two, until he started to feel some strange pain. His eyes were hurting badly. When they made it to the top of the wall and Armin received Eren, he walked away looking for some water. Nobody approached him. In fact, Eren got all the attention. Some were worried about him, as usual, and some others were celebrating and thanking him for the success of the mission.

Armin walked towards him some minutes after Eren had awakened. "Corporal Levi, are you alright? That last moment seemed very horrifying from here." He talked softly, but Levi was on the floor beside some boxes and bags, too keen on finding a canteen full of water. "Sir?" He talked again. "Sir? Seriously, are you alright?" Armin got close to him and looked at his face covered in titan's blood.

Levi finally found what he was looking for, looked up and spilled the water all over his face, while Armin's expression went from worried to horrified. Levi's eyes were burning. "Corporal, what's wrong?" He didn't answer. He spilled more water into his eyes, but it only ended into a groan of pain and some steam, like when the titan's blood is evaporating.

"Corporal?" Armin called again, noticing now that Levi's eyes were bleeding. He then reacted instinctively and went over the others. "Help! Corporal Levi needs a medic!" He screamed frightened for what he'd seen. Meanwhile, Levi was utterly immobile. He wouldn't move even an eyelash. He was paralyzed because of pain, that pain in his eyes that was killing him, burning his eyes.

Everyone approached to them and saw Levi in that position: kneeling on the floor and looking up while his eyes were bleeding.

"Levi, what's wrong?" Hanji asked, terrified as same as the others.

"It… hurts." He hardly managed to answer back. Then he closed his eyes, but the blood was still falling through his cheeks as if they were tears, and they were still hurting. Erwin then knew that they needed more than a doctor.

They had trouble with getting the way back to Rose. They still had to clean the area between Maria and Rose from titans, but they just couldn't without Levi. Everyone knew that. That was the reason they had trouble getting back, because they couldn't fight. That way back took 20% of the men left, as if it weren't enough with the ones who died during the way to Maria and the two days of building.

Erwin didn't wait to get to Trost to find Levi a doctor. In fact, as soon as they got to Karanese, he dismissed the troops and went straight to the hospital together with Levi, Hanji and the most worried of all, Eren. There were a couple of soldiers from the Garrisons waiting to be treated, but Erwin just manages to get Levi treated as soon as they arrived.

They were all frightened, fearing that they would lose the mankind's strongest soldier. Levi had already lost a lot of blood and started to feel weak, which was something to worry about, especially when he himself had admitted it. Hanji quickly explained the doctor what happened and that what was burning Levi's eyes was titan's blood. Then, the man took a look again to Levi's eyes and, judging by his glance, what he was about to say was no good at all. But before talking, he asked them to leave the room and talk in the hallway.

"Well, the damage is too severe. His corneas were completely burned and, judging for his upcoming fever, they already got infected. It also seems impossible to recover them. Even stopping the bleeding appears to be impossible. " He explained slowly as he was sorry for what had happened and for what he should do in order to save him, so to speak.

"What does that mean?" Hanji whispered scared as hell. "He won't be able to see again?!" Hanji abruptly asked, almost freaking herself out. She knew very well that losing Levi from the Scouting Legion would be a terrible loss to humanity.

"Not just that. We'll have to remove his eyeballs." The doctor replied and looked at Erwin, knowing that he was the one to give permission to that and continued explaining. "Waiting for it to heal would be twice as dangerous than surgically removing his eyes because of the infection they got, which, since was caused by titan's blood, we don't know if we could control. We don't know what kind of medicine to use either."

"But… Hasn't he lost enough blood already?" Eren shyly interrupted. "He wouldn't stand a surgery, would he?"

The doctor sighed and shrugged. "Yes, he has, and no, he wouldn't. That's another of our problems. The more we talk, the more he's near to death because of the infection and the continuous bleeding, which isn't even from the eyes themselves but from the sclera."

"The what?" Eren suddenly asked. He seemed not to understand.

"The sclera, the outer layer of the eye. It's the irrigated area of it. That's why it's bleeding so hard." He explained again, starting to lose his patience. Then, the three of them stared at Erwin's face.

"If we let him keep his eyes, he'll have a painful and long death. But if we try to remove his eyes, we'll take the risk of him to die, but the hope for him to live?" Erwin slowly asked, still thinking. Like if it were a hard decision for him to make, more than it already was.

"Exactly." The doctor replied. "Then go ahead. Do it. Save him." Erwin added quickly, without hesitating.

Well, I hope you liked this. If there's anything you'd like to suggest, feel free to leave a review. Don't forget to bring me words!
