Erchinor was founded by Ithendelt exiles. Led by House Glorfindel, they parted with the single family rule on the other side of the Core Sea, establishing a government of family heads, called the Gilraen Oligarchy. The major threats for them were the pirates of the Core Sea and fire giants coming down from Steirgar's peaks.
In 1420, the Khazarkar Empire began encroaching on the territory of the Gilraens. Needing to secure their land, they wanted the Gilraen Oligarchy to submit to vassalage. The Gilraen-Khazarkar War, over in a month, made Gilrean a vassal state.
Under Khazarkar oversight and protection, Erchinor prospered, and for the most part lived in harmony; some would say too close for Khazarkar ideas of racial purity. The only thing Erchinor had to give up was their religion. The reluctance of some to forsake Arcana, led to banishment, imprisonment or execution. This created rebel elements that still to this day wage an insurgency from the Salbâth Valley. Known for their long history of studying and worshiping the Goddess of the Arcane, some went north and then down into the Underdark where they joined up with Eldritch Concalve at Malardân.
Erchinor was the capital of Gilraen. On 14 Lunar 1830, Erchinor, before the Cinazan Front, a city of 45,000 inhabitants, was sacked by the Flux Pact. Like the other cities ravaged by the 1st Horde of Chaos, the ruins of Erchinor are twisted, discolored, distorted and infused with entropy, it became a Chaos Ruin - streets that once ran straight, are twisted and stop at the crumbled wall of a building, or end in a pool of smoking rainbow colored ooze. Piles of rubble and even parts of buildings float at various heights over the area. Jets of fire erupt from nowhere and then vanish, storm clouds roll across the area, with the rain going in all directions, or air elementals dancing about the ruins spraying debris at anything that moves. The ruin is also a haven for numerous fell taints and at night, bands of grell emerge from the sewers emptying into Faeglor.
