Conquered the world!

Relax, man, Hax was correct, if a tad condescending. Terhazza controls all of the major desert tilesets outside of Gedrosia. The Sahara and the Arabian Desert are actually the same province. I believe that this was done to represent how no organized factions actually controlled the deserts and to prevent the Ptolemies and the AS from bordering the Saba too quickly. If the Saba controlled the Arabian Desert in-game, they'd probably get crushed within 25 years.
