The city of Mecca was the Muslim holy city, and because of this after the Byzantine Empire had conquered their neighbors, they had ceded control over it, and the city of Medina, along with a bit of land connecting the two of them to the Iberian Empire which was ruled over by the Sultan Ghazi Al-Fadl. Who, at least on the surface, appeared to be a rather devout Muslim man.
Naturally, due to the significance of this city, Berengar had elected to establish an embassy inside it, not to the Iberian Empire, for that embassy was within Madrid, but instead as an embassy to the Muslim Faith.
It was quite rare that the Ambassador to the city of Mecca had to actually do any work, but today was not one of those days. Because immediately after waking up and opening up the facility, he and his staff found a group of desert nomads waiting for them.
