The Rhenn Plains are serene and peaceful, beautiful, and quiet as if nothing had ever had happened to it, hiding away it's violent present and past. During some time ago, the countries needed land to fight on, for they did not want war to come to their home, so they chose the Rhenn Plains, Armies met there and men died on the lands, so the land has been empty always. But now there has been set an outpost and they are beset by the goverments wanting to keep it free, will the soldiers of the barracks prevail, or fall trying?
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.
