Well, this fic is my first time-travelling one, and it needs some explanations, so please don't skip the following:

You all probably heard about the Philadelphia Experiment, a.k.a. "Project Rainbow", an experiment of the US Navy in 1943. For those of you that don't know about it, the purpose of this experiment was to make a ship invisible, using Einstein's "Unified Field Theory". However, I've read a book written by Brad Steiger, which has an interview with Alfred Bielek, someone who supposedly took part in the experiment. Bielek claims that Nikola Tesla has been working for the US government since the end of the 1930s. Apparently, Nikola and the other scientists working at this project managed to make a mine layer turn invisible in September 1940. However, nobody was aboard the mine layer when this happened.

After the Japanese attacked Pearl Harbor in 1941, the government decided to repeat this experiment in March 1942, this time with men aboard the ship they wanted to make invisible. Tesla protested, claiming that the effects of this experiment on humans were completely unknown, and he asked for more time. However, the Americans said that their country was at war and that there was no time to lose…


It was almost 10 PM and Nikola Tesla was pacing the corridors of the White House, wondering why Mr. Roosevelt had called him at such an unusual hour. It most certainly had something to do with the war going on, given the fact that only three weeks earlier, the German U-boat offensive came closer to the US shores.

Nikola didn't understand nor like war. He wasn't worrying for himself, because being immortal meant that he would be safe no matter what, but there was someone who was in danger, someone that meant very much to him. He hadn't heard nothing of her since the war had begun, because she was working so high in the Ally Forces that she wasn't allowed to contact him. She was probably facing life threatening situations every day and he wasn't there to protect her. Not that she would have wanted to be protected. No. That wasn't her. She was the most stubborn person he had ever known. But there was something about her, something that had made him fall in love with her at first sight. Where was she now? James didn't know more than he did, and Nigel…Well, things hadn't worked so smoothly between him and Nigel since The Five had separated.

"The President can see you now, Mr. Tesla." Roosevelt's secretary said, interrupting his thoughts.

He followed the secretary into the library. Roosevelt, which waited him there, was reading a book, but immediately stopped when he saw Nikola.

"I'm so happy you could come. We need your help, Nikola."

"What happened?"

"Sit down. Have a glass of wine. We need to talk."

Nikola poured himself a glass of wine and, when the secretary left, Roosevelt said:

"I don't think I have to remind you that our discussion is strictly classified. We have to talk about Project Rainbow."

"What happened? Things went well two years ago, but you haven't said a word since."

"Because what happened two years ago is completely useless. I don't want to offend you, Nikola, but making a mine layer turn invisible is completely useless when it comes to war."

"What are you trying to say?"

"We have to extend our experiment. We need it now more than ever to work on humans too."

"You mean make a crewed ship invisible? That's impossible."

"Nikola, you are a vampire. Don't tell me that you still believe that there are things that are impossible."

"That has absolutely nothing to do with what I am, Mr. President. The effects of this experiment on humans are completely unknown. We may make some tests; start with little animals, such as rats, and maybe in a few years' time we will be able to do it on humans too, but that's all I can give you."

"I don't have a few years, Nikola! The press is on my trail every single minute. After what happened at Pearl Harbor, we have to show the world who we really are. Show them that nobody attacks America without being destroyed. And Project Rainbow is the best choice that we have. Imagine an invisible fleet attacking Germany or Japan! We would be practically invincible!"

"It is too dangerous. I could try to design a wireless system of controlling ships without men aboard, but this is all I can do."

"Nikola, it's everything or nothing here. You have to understand that I have no other choice. We have to finish this project, and we have to finish it fast. Otherwise, we won't be able to defend ourselves anymore. We need a unique advantage in this war and Project Rainbow is our single hope."

"With all due respect, Mr. Roosevelt, but I don't think you understand the possible consequences of this experiment. We are talking about a massive amount of electricity. I don't know if humans are capable of withstanding such voltage. Not to mention that if we keep them invisible for too long, this could affect their health on an indefinite time period."

"Why?"

"Because my method of making somebody invisible is based on transporting them into the fourth dimension. And frankly, I have no idea of what could happen to a human if he stays there for too long. I was transported myself into this dimension, and if it hadn't been for my assistant to cut the power and set me free, I don't know what might have happened. And keep in mind that my physiology is special. I don't think that a human could resist such travel."

"I have faith in you, Nikola. Besides, I need you. No one else can control the Zero Time Reference Generator. Not to mention that the amount of electricity that you can create is astonishing."

"I still don't like the idea. However, if you find me someone that can guarantee that nothing will happen to the men aboard if we do that, I might reconsider. But only then. "

"I already did that, Nikola. I know someone that can help us, medically speaking. You will work together."

"I can't trust anyone, Mr. Roosevelt. You know how complicated my condition is. Faking my age so the press thinks I am a pitiful old man is enough trouble for me. I don't want to imagine what would mean to work with a human, to have to hide myself at every turn… You know as well as I do that this would work much faster if I could use my electric powers and working with anyone else would mean that I can't use them."

"You don't need to worry, Nikola. The person I want you to work with is an old family friend. Someone who has been working for the Allies since the war begun. As a matter of fact, my cousin Teddy was the one that introduced her to me."

"Yes, but still, I am more of a one man show. Maybe I could make some tests, send the results to your friend, and if everything goes well…"

"That is completely out of the question. She will take part to this experiment and so will you. You two will share the command of this experiment. I need you both to make sure that Project Rainbow will have the results that we want."

"I'm sorry, but I don't know if I can trust this friend of yours."

"Well, she was supposed to meet me tonight. You will meet her too and trust me: you will have confidence in her."

"I'll give him a shot, for your sake. Wait a minute. Did you just say she?!"

"Yes. She is a woman. I don't know why the hell she is late. British people are normally very punctual."

"British?" Nikola said, coughing on wine. "Mr. Roosevelt, you don't say…"

The door creaked open, revealing the woman Nikola had been hoping to see for almost three years now.

"Well, Nikola, it has been a while." Helen said, entering the room.
