Prologue: The Story of the One Bomb
It is written in the electronic records at the Nucleus Spytech facility that a long time ago, there was a wealthy Englishman named Zepheniah Mann. He had two sons, Redmond and Blutarch, and an aide named Barnabas Hale. While Redmond and Blutarch constantly competed for his inheritance, Zepheniah had secretly decided that he would leave the company to Barnabas. So when Zepheniah passed away, Redmond and Blutarch were left with nothing, and so they created their own companies called RED (Reliable Excavation Demolition) and BLU (Builders League United), respectfully. To protect their interests, they hired teams of mercenaries with different skill sets to sabotage each others' companies, and this inner war went on for several years while the Hale family provided weapons for both sides of the conflict.
Then one day, a mysterious woman appeared and offered powerful bombs to the Mann brothers and the Hales in exchange for peace. The Mann brothers accepted them gladly, but ended up using them in further conflicts, while the Hales never used the one they had. But none of them knew that another bomb existed. Forged in the factories aboard the Moving Fortress (the place where the Robots emerge from), this bomb was more destructive than the other bombs combined and yet small enough to fit into a man's coat-pocket. The creator of this One Bomb was Gray Mann, a third son of Zepheniah who was kidnapped as an infant and never mentioned again by his father. Without warning, he assassinated Redmond and Blutarch, thereby causing all their mercenaries, who were clones of the originals at this point, to become unemployed. Then he attacked the areas RED and BLU owned with armies of Robots.
So an alliance between the Hales and the cloned mercenaries was made, and they fought against the Robot army. Many lives were lost, including the Demoman Eallair, who was slain by Gray Mann himself. So his secretly-conceived son, Iomhar, took his father's broken Claidheamh Mòr sword and killed Gray Mann by destroying the Australium that powered his artificial body. However, the One Bomb was still intact, and when Iomhar had the chance to destroy it, he didn't. Instead, Iomhar took it with him on his journey back to Scotland, but along the way he was attacked by lingering Robot Snipers.
As a fatal arrow caused his body to fall into the river near Lumberyard, the One Bomb swept away and lay in the shallows for centuries undamaged until it was found by a strange creature called Mumble, who was neither man nor animal. He took the One Bomb to the mountains near Coldfront, and there it remained with him for many more years. Then, the bomb was found by an unlikely person. His name was Bobbie Billows, a Scout from the Harvest area in the Farmland environment. He was on a quest with a group of thirteen Engineers who were trying to reclaim a factory that had once belonged to them, but that is another story. What is important is that the world is changing, and the Scouts are the catalysts of that change…
