Found It!
'This Morg Abian Empire isn't simple,' Landon noted when looking at the cluster of vast established structures scattered around.
It would be a lie to say he wasn't impressed.
It was neater than any empire's Capital had been before Baymard's arrival.
It was organized, and from what he gathered, every little part of Abian, including villages tucked away, all had nicely stone-carved roads that facilitated travel.
As you know, good road access facilitates not just travel, but the movement of goods, supplies and even troops.
Wagons moved two times faster without having to worry about large potholes or large dips caused by the terrible weather, boulder battles and even ordinary horse stomps.
When moving on uneven and bumpy roads, travel must slow down for those with goods.
Horses couldn't rush or else their reins might snap and all perhaps their wagons would roll away, leading to a crash and spoilage of goods.
