There's a lot of things, in terms of backstory with the other characters and things that you don't see, that I have specced out in my mind. I thought it would be interesting to present them in text form to fill in some of the gaps, as it were, in the main ZAGS storyline. Each of the main fics are intended to be canon with at least one path through the game.
All pieces here are extremely spoilerific, and it is recommended that you do not read them until you have finished the game.
Each piece is presented with a short summary, below.
