In 328 C.E., the five main cities, Sidereal, Helmskeep, Bronze City, Whitebeach, and Phobos form the United Five for mutual trade and defense. Fifty years later in 375 C.E., the evil Emperor Shaelong and an army of 25,000 invade. The City of Phobos has been completely destroyed and no longer exists.
