"I walked through the poor’s quarters, and my eye was not harmed. All functional, and simple, and crude, made on the whims of fate and delivered by immediate need.
I walked through the merchant’s quarters, and my eye was bored. Pretensions where nothing backed them, striving for appearance without substance, evidence of changing wealth, too much only began, too much never finished.
I walked through the place where the powerful lived, and my eye was tired. Too much of attempted beauty turned hideous, and a lack of taste was made worse by willing lackeys.
But then I’ve seen the treasure of the city. A cathedral, that was part of the sky, columns, and arches to carry the weight of the world, shapes to let your mind fly along, and ornaments to stop by. A place to ponder, to be pleased to be alive, to accept suffering, and to realize your mistakes. This is a place I could learn from."
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.
