Alexandria
As time passed, a single city rose above the rest. Strangely enough it was spearheaded by Alexander the Great, oddly enough he went on to create a citadel that dwarfed any he had ever dreamed. This citadel drew other powerful men and women, around it formed a city that became the most important location in this world. By many it is considered the central hub of the world.
Its Alexandrian venues and streets with parallel rivers give it an otherworldly appearance. It is timeless in its beauty, with towers of marble concrete. A strange but beautiful creation of this world. Where marble was harvested and ground down, mixed with stone, white paint and tar. This strange off-white beauty makes these streets both sturdy and breathtaking.
As with any great city, there is a major center for commerse and trade. As well as restaurants, bars, and gentleman's clubs surrounding the trade center. As the Greats adapted to this world where language meant nothing, they came to accept this new life. Creating civilizations among their own kind. With great leaders spearheading every great citystate, there was little in the way of total war. Though constant skirmishes were wholesale, these people thriving on battle did so to entertain their violent tendencies.
As a major centralized city center, there are travelers from every corner of the world. Aliens and demigods, warlords and god emperors. Alexander's citystate became the home to so many cultures and societies. It was set to prosper eternally, and with Alexander unlikely to ever leave his seat as leader, this was the way things would remain.
