"Traveling around the empire was excruciatingly slow"

"The researchers estimate that it took 7 weeks to travel from Constantinople (at the eastern end of the empire) to London (in the far west)."

What a funny little empire with nice roads :). Check this empire:

"And say, the governor went to Yakutsk, not months, for three years. The first year we reach Tobolsk. The second - to Irkutsk. And in the third year of riding on horseback to the upper reaches of the Lena and floated with water to Yakutsk."
