Xerxes

Though not much detail is known, it was a city-state east of Amestris that was destroyed long ago. As the manga depicted, the entire civilization was destroyed in a single night, with its entire population sacrificed to create the Philosopher's Stone. In the real world, Amestris was the queen of the Persian emperor Xerxes. In Chapter 74, it appears that Xerxes is the homeland of the slave boy who came to be known as Van Hohenheim. In the U.S. release of the manga, Xerxes has been mistakenly transliterated as "Cselkcess".
