From the introduction:
Welcome to the world of antiquity. The year is 83 Anno Deum and the world as it will exist in the 21st century is as unimaginable as it is impossible. Rome languishes at the height of decadence, denounced only by a radical Jewish cult. Greece lives more and more in her jeweled past, coveting the achievements of Pythagoras, Plato and Diogenes to name a few. Parthia, shell of the mighty Persian Empire is an emasculated Roman vassal, but still produces some of the world’s finest art and poetry. Most of Europe is a backwater, inhabited by barbarians and harvested for slaves. The Arabian Peninsula is torn by tribal warfare punctuated by islands of civilization.
Irem is one of these islands. Rising like a forest of marble from the shifting sands of the Rub-Al Khali desert Irem is a dusty jewel where anything and everything has a price. Located on top of a lush oasis, the city serves a vital caravan stop for traders from across the ancient world, within its walls you will find merchants, thieves, scholars, priests, alchemists, mercenaries and cultists from nearly every corner of the ancient world. The metropolis spans for miles and holds thousands.
None of them know that Irem, City of Pillars is about to disappear.
