Azim Balda

"And on the fourth day we arrived at the city of Azim Balda. Now Azim Balda stands at the meeting of many roads and from it the posts of the Tisroc ride on swift horses to every part of the empire: and it is one of the rights and privileges of the greater Tarkaans to send messages by them. I therefore went to the Chief of the Messengers in the house of Imperial Posts in Azim Balda."
