The Persian Royal Road is one of the pre-existing roads at start.
The routes we have in the game will take you from Sardis to Syria (via Cappadocia and Cilicia), from Syria it continues to Egypt and Babylon (both a northern route via Niniveh and a southern route along the Euphrates). From Babylon it continues into many of the cities of Persia and all the way to Parthia and Gedrosia.
