Partially fault of mine, most of the information and details of the Aeons and plot structure are not listed here for the sake of not overwhelming the introduction. It's done purposely for the plot/story discovery.
Essentially, I could say wait for the ooc, but I'll explain for others with the same inquiries:
The plot is a mixture of linear and sand-box, and is mostly swayed by the decisions of the cast. There is a timeline already written, however it's vague and conceptual so I don't lose myself from the story.
You're a part of SOLDIER, you're going to be doing what you were trained and conditioned to do: fight.
SOLDIERS are, basically, better than everyone else - to keep it simple. Faster, stronger, intelligent; possessing super-human traits that everyone believe to be derived from a divine influence and origin. Could this be the case? Who knows.
The cast is either selected; volunteered; or joined into the programme by affiliation. For example, your family is military bound or related to one of the scientists also leading the division. The plot and story begins after having been under SOLDIER for some months, already trained, prepped and being given first deployment to where you'll be fighting and putting down SeeR factions.
I can't specify any more without giving it all away, heh.
The Aeons were used for experimentation purposes in the beginning, when man discovers something new and foreign, he needs to know what it is, how it got there, and what it can do. This is what they did with the Aeons. Now, in the current events, a lot of people have forgotten about them. War blinds everyone, in this case. SOLIDERS, mysteriously enough, don't know anything about them. Public announcements were given, stating that the Aeons were no longer present or alive and effectively sealed away or deposed.
Aeon genetics and cells were the original cause of the war, but like I stated, they've been forgotten. Now Viera is under war for the sake of resources and, to some, to break away entirely from the capital. Granted, not everyone has forgotten about the Aeons, but very few are probably aware of their original purpose and intentions during the early pharmaceutical campaigns.
The Aeons, however, are closed tied and related to the cast.
How, exactly, will be explained in the ooc.
