"Master Loki!"

Loki looked up, "What is wrong?"

"The Master collapsed and we can't feel him anymore! Please go to him to help him!" The elf begged Loki.

Loki frowned. How did Harry collapse? "Take me to him." Loki ordered.

The House Elves led Loki to the library.

Loki was confused. "Why is he in library if I may ask? All the wards are down, I'm not sure if I can get through them."

One of the elves wrung their hands, "He's been researching for months and he didn't want anyone to get it."

Loki turned back to the doors with concern written on his face. "Then it is time to get him out."

Now

Loki didn't hesitate before he started sprinting. Somewhere in the back of his mind, he realised that although he never went back to the library all these months, the hallways looked familiar, as if an old friend was greeting him after months apart. It was a foreign feeling, yet he wasn't disturbed by it.

In the corners of his eyes, Loki saw the big pillars passing one by one. Five… six… seven… On and on they went. A lovely pattern. A pillar, a door, a pillar, a door. It's funny to realise that Loki once thought that the house wasn't big. It had nothing on the palace of Asgard and yet while he was running through the house it seemed so much bigger than Asgard.

Loki kept on running and soon he saw the familiar door of the library, it was a beautiful door, full of inscriptions and figurines. The first time he had seen the door he was completely in awe of it, but now the door filled him with dread, not knowing what was on the other side. Only knowing that it would be awful.

With the doors towering over him, Loki took a deep breath before throwing the doors open and walking inside.

Rows and rows of books welcomed him in. A table stood here and there, but Harry was nowhere to be found.

"Are you sure that he's in here?" Loki asked the elf that had followed him.

"Yes, he's just a bit further in, please help our Master!" The elf cried out, wringing their hands.

Loki looked dubious, but indeed, there was another section a bit further on. Walking towards it, he saw a shadow emerging from the darkness. It was quite big, was that Harry? If so, why were the House elves so worried. Harry looked bigger than the last time Loki had seen him.

Every step brought him closer to the shadow and every step brought out more details. The big outline became more prominent and rugged. As if it wasn't the outline of a person, but multiple objects stacked on one another. The weird thing was that it was making a noise, a soft muttering could be heard if you strained your ears.

It was repeated over and over again. "Almost done, almost there, just a bit more…" It was said in a haunting voice. Rasping as if it was used too much or perhaps not at all. Either way, it was too dry to make out whole words. You could hear the voice trailing off at the end of the words.

Loki stepped a bit closer, finally seeing that the shadow was mostly books and scrolls. There were even platters of food if you could call the rotten remnants of fruit and bread food. Now that Loki saw it, he could suddenly smell the scent of rot and decay. The smell brought back up horrible memories of his time stuck in the dungeons of Asgard, he had smelled the same.

Putting his hand over his nose, Loki set the last step that took him around the books. What he saw was enough to make him want to throw up. His saviour was sitting there with a face so gaunt that it would have surprised Loki that the skin was pulled over his skin and that a hairdryer had been used to crease out all the creases. A spiderly hand rose and grabbed a new scroll.

The hand looked more alike to the hand of a skeleton than a real human's hand, the skin was seen through and those veins and muscles didn't look healthy at all. Loki could see the blood pumping through the veins at a sickly, slow pace. It looked as if the heart had given up beating.

It was a good thing that Loki has good eyes otherwise he wouldn't have seen the slow rise and fall of Harry's chest. To the normal human's eyes, the chest would be completely still. No movement to be seen.

Loki truly couldn't believe his eyes. What in the name of Frigga did Harry do? He was just supposed to do some research, but this? This was way too much for it to be healthy. Why didn't one of the elves stop him? Why didn't they get him sooner? Why didn't Loki think about him earlier? Why didn't he look for Harry after he hadn't seen him for weeks? Before he had seen Harry almost every day. By the gods of Asgard. When Loki was ill, Harry had set by his bedside. Waiting for him to be better. How could Loki ever deserve someone like Harry?

Harry had done so much for him and what had Loki done back? He had completely forgotten about him. Never mind the fact that he was relearning everything about his children. Harry had worked himself to the bones, literally, looking for a solution. How could Loki have been so blind…

Loki's breath started to hitch and blackness started to fill the edges of his view. Dropping his hand on one of the piles of books, he accidentally dislodges one of the books and the entire pile collapsed. The loud noise caught Harry's attention.

Blinking slowly as if he couldn't believe his eyes, Harry looked up and down Loki's form.

"Loki? Is that you? What are you doing here?" Harry asked confused. "I thought that you were with your children, did something happen?"

Loki closed his eyes with a pained expression on his face. "Harry," he rasped, "what the hell did you do?"
