The Trace On System, abbreviated as either TOS or TRON are a series of epidermal implants and nano-fiber filaments implanted to improve the reflexes, balance, and agility of the augment wearing them.
Blurring the line between exoskeletons and cybernetic augments, the D9 is unfavorably comparable to the Chemical Augmentation System.
By the Cosmic era, almost every part of the human body is replaceable, including of all organs, the brain.
When the Liberty special forces medical research and development teams needed to rebuild man, they didn’t do it by halves. The result? A suite of augmentation so pervasive, that most modified operatives are more effective on their own than half of the Liberty marines put together.
As the PCs travel the road, right after a bend they hear a sharp whistle and call: "Heeey, not so lazy, move your asses!" It is a large man that calls, and there are unwilling workers that listen. A small company, 10-15 men work on the road, push boulders aside, dig up roots from under the road, etc. The large man that shouted turns to you, smiles fast and mutters something under his breath, sounds like cursing some lazy worker. "Where does the road bring you from, travellers?" And does a little small-talk.
And what is really happening? A group of bandits is 'adapting' the road for shady purposes. The road will not be wider, but tighter, with enough cover around (and a few traps perhaps), and will become an ideal spot for ambushing travellers or entire caravans. The bandit leader wants them all to appear harmless. The 'lazy worker' he cursed was actually a guard that should give warning before any travellers come around (fallen asleep). Not surprisingly, the boss may decide for an ambush even now.
