Causing the ripple effect
prologue
Time, time is like a calm lake, ever so peaceful ever so surreal.
It will only take a small pebble to drop in the middle of the lake to cause the ripple effect.
But unlike the ripples in the lake, ripples in time will become waves that wash all across the timeline.
In the year 2186 CE the pebble was thrown at the timeline, and it caused unimaginable waves.
2186 CE Citadel Unknown Location
The intelligence was waiting for commander Shepard to make a choice.
Commander Shepard looked at the intelligence with a tired eyes and said "you are asking me to make a choice? Even though we both know there isn't really any choice". The intelligence looked at the broken and tired Commander "i see…. You are truly remarkable specimen, most of other orgenics and even synthetics would be still ignorant at this point, but you… you are aware".
A second had passed then another, then a minute than 5, yet Shepard hadn't moved, he felt as if a eternity had passed, but he just stood still stared at the intelligence.
Destroy, Control or Synthesis those are the "choices" that the intelligence gave Shepard.
Shepard looked at the Earth, he could still remember The Illusive Man last wards "There...Earth. I wish you could see it like I do, Shepard. It's so... perfect." yes, Shepard thought while looking at the Earth, it really is perfect.
How Shepard wished the he could as the The intelligence told him Destroy, Control the Reapers, but he could feel the presence in his mind telling him to choose the Synthesis option.
The Commander is no pushover he tried to fight it, he tried to go and Destroy this citadel the Reapers and that damned intelligence, but his feet slowly walked to the Synthesis option, yes they managed to indoctrinate him.
Slowly walking to the edge of the platform he thought about all his friends and his loved ones, how in the end he failed them. The Reapers will get what they wanted all along combination of both organic and synthetic.
"Wait!" yelled Shepard, stopping just at the edge of the platform. While still looking at the beam of light that originates below the platform. "Can you tell me at least why do you want to combine organic and synthetic life? Why not just kill me since i'm already at your control why to you need me to jump into this light".
The intelligence contemplated for a few moments whether or not justify the Commander with an answer, after a few moments it said "the crucible rewrote some of my core functions, it give me new insight, but i'm unable to initiate them myself. I need an outside source, a template if you will that i can build upon, hence you." after a few seconds of pause it continued "with the combination of both organic and synthetic i can finish my prime purpose given to me by mine creators, in this galaxy." the Commander could not believe his ears "in this galaxy? Are you planning to go to other galaxies? What if the people do not want to fight?" the intelligence answered "yes, we will go to other galaxies to restore order in the chaos, and there will not be any people who do not want to fight, they will have no choice, i will be in control, now….continue".
No, thought the Commander, i can't allow this to happen, but there is nothing i can do. With a tear in his eye Commander Shepard, an orphan that was raised on the streets of the great megatropolises covering Earth, a war hero almost single-handedly repelled an attack by batarian slavers on Elysium, a very powerful biotic, the first human spectre, jumped into the beam of light while feeling as the intelligence deconstructing every cell in his body, combining and changing them at his will, the pain was to much for any organic to bare, three words were repeating in his mind over and over "i failed them".
The intelligence didn't wait to finish deconstructing all of Commander Shepard, it instead instructed the citadel to open its arms and prepare the Synthesis process. But unknown to the intelligence a solar flair was heading towards the citadel station and when it finally hit the station something remarkable happen, the combined energy of the solar flair and the energy that the intelligence was using for the Synthesis process created a rift in time and space, a tiny one but nevertheless it was enough to send something through. As soon as Commander Shepard saw this he used his remaining biotic energy to propel what is left of his body, in hopes of kill himself in order to end his pain.
As the Commander got near the rift he felt his body began comprising and into something smaller,finally he can end the pain and guilt that he felt, then it all went black.
While it the vortex the Commander's body continued to be compressed, his consciousness was long gone but his soul remained it was clean and pure like that of a new born.
