Elemental Power Project

"'And how is the elemental power project going, might I ask? Would you tell me well, or tell me it's off? Your answer shall be destiny.' -Lord Seiko Chikatilo"The Elemental Power Project is a project dedicated to stealing the elemental power of a chosen elemental subject.

History
There have been five targeted subjects for the project, in this order: Kori, Kaen, Ki, Hira and Akua.

Kori: As the energy build-up reached its climax within the machine, it blew up, unable to contain all of her ice powers. Three years wasted...

Kaen: Once the last attempt failed, the next victim was Kaen. Luckily, it was realised that his fire power would heat up the metal inside the machine, ultimately destroying it again. Despite being chosen as the next victim, he was never captured, and nobody outside of the shadow nation knew that he was even a target in the first place.

Ki: The third victim was Ki. His elemental power of nature was tested, and proved that the machine wouldn't break if the metal was strong enough. He was captured, and went missing for three days. The Storyteller, however, sent him another vision. To remove the effects of the unconsciousness caused by a dark form of magic, she granted him unbeatable strength for a short amount of time. He left the base, and completed his original purpose for heading there (in an unexpected way): he broke out with Kori.

Hira: If the elementals had been aware that she was still alive, she would have been rescued along with Kori during mission ice. It was not until Seishin, the elemental of spirits and all things dead, had been recruited that they realised she was still alive. She used a special technique to discover one living soul inside the nation. Another rescue mission occurred; this time, it was called mission flower. Unfortunately, the mission was unsuccessful. Hira died inside the extraction chamber, and all her spirit energy was released along with the elemental power that had built up inside the machine.

Akua: It was during mission flower that she was targeted. Whilst inside the base itself, she stayed with her mother right until she died. She was unfortunate enough to be in the firing range of several tranquilliser darts, and fell unconscious, then continued staying unconscious due to the dark magic that kept most people asleep. The extraction chamber dedicated to taking water powers could do so within an hour, to make things worse. She lost all her powers, but the machine released it again because Kaen was smart enough to install a manual override into the system. The manual override destroyed all the extraction units, but mission flower was still completely unsuccessful; Hira died, the completely opposite objective, and Akua was unable to use her powers due to a mind block that would undo as soon as she left the shadow nation.

How it works
There are several different types of extraction machines, each one dedicated to a different element. The unconscious subjective elemental would be chained into a seat, and a needle would slowly suck out their magical energy (hell of a good thing they wouldn't be awake... sheesh), leaving them weaker than before. The needle cannot carry a lot of energy, and it also has to compute the data, which also takes a long time. Depending on how much energy the subject has, the time varies. Nooki Ai, the elemental of love, would likely have her powers removed within a week.

Akua is the only subject that contradicts this rule. The technology used in the creation of the machine designed in her case could remove all of it within an hour, which was enough time during mission flower to completely drain her of magic. She had a mind block - during which she had numerous shadow nation visions, and was completely unconscious. Once she was carried out of the shadow nation, she woke up and recovered her powers back again; Kaen had installed a manual override upon realising she was no longer an elemental, which just blew up all the machines in the shadow nation.
