My death is near and while I have seen or heard about all these events, they are quite a ways in the future. All I pray is that you, finder of my collection of notes, takes action to keep the Team Fortress Industries from leading to near apocalypse. How? I can't tell you, but by the heavens, do something!
My name, by the way, is Vale Pauling, Mr. Pauling if you'd like.
This story is going to be scattered between it's characters; I can't give you much better. I couldn't have been through all of the events that followed so I could only talk to those whom I had time for. I'll happily give you small tales of light between the steps of the darkened path through these people walk.
My best guess as to when things started to go wrong is when The Administrator of the time, Helen Bryer, hired and started manipulating Persy Vidal. Now Persy was Valerie Vidal's third son, her youngest being Jack Vidal. Jack was the top RED Scout, confident (like all members of 1 teams) but kind enough to those who treated him well (like most members of 1 teams). Now if you don't know what I mean by 'top Scout' or '1 teams' then let me explain. Team Fortress Industries, at the time, had the RED, BLU, and GREEN teams. These teams were made up of twenty groups of nine mercenaries, each of their own class. Jack Vidal was known to the systems as RED Scout 1 - Identifying his class, his team, and his 'group.'
Well, Persy wanted to destroy TFI; an insane feat, as by that time TFI had a major influence on all of the world's governments. Once Helen got a hold of him, she let him have an illusion of freewill. Really, she was the one who'd led him to Gowan MacClennan and gave him the plans to give to BLU Demoman 1.
Gowan MacClennan told his team the plan, and led them in carrying it out.
Gowan, Nicolai Arkadiy (the Heavy), Fagan Elenek (the Pyro), and without the knowledge of his team, and against the plan, Spencer Cheston (the Engineer) went to the GREEN Rotation Base. While his teammates booby trapped the base and got ready to kill those inside, Spencer desperately worked to find a way in that he wouldn't be seen. You see, Spencer had a younger sister named Daisy, whom worked as the top GREEN Engineer; and he wasn't going to just lay back while she was brutally murdered.
I'm sure your first thought is, "What does it matter? They have respawn right?" Well, the answer is yes, but Gowan and the others were making sure the respawn was the first thing to be destroyed.
Inside the base, Daisy and the Pyro, Holly, were inside the aforementioned respawn. Daisy was simply working on her teleporter design, while Holly was bored and setting various things on fire. A blue sticky bomb attached itself to the respawn window with a light 'tink', only getting the attention of Holly. Holly, of course, did what she did best; set it on fire.
The explosion (which only occurred due to a fault in the bomb's shell) triggered the destruction of the base before Gowan was quite ready, but did take out about half the base (How the man had that many sticky bombs on him escapes me), including the respawn. Holly was killed just short of instantly by the explosion, while Daisy got by with very bad burns - only to be crushed by falling concrete after. This is my best guess at least, I wasn't trained in autopsy after all...
