Amdapor was not always thus afflicted. Indeed, the city once owed an age of prosperity to the benevolent art of white magic. But that was before the War of the Magi. It is told that the enemies of the Amdapori abandoned all caution in their pursuit of victory, and used their dark magicks to summon a king among demons.
Amdapor (アムダプール, Amudapūru?) is an ancient city in Final Fantasy XIV that existed in what is now the Black Shroud during the Fifth Astral Era. It was the birthplace of white magic, which had been developed in response to the great sorceress Shatotto's invention of black magic. The city would eventually be consumed by the War of the Magi and the resulting Sixth Umbral Era.
As its history is entwined with that of the Twelveswood and the art of white magic, most research on the city has been conducted by the padjal of Gridania. It is said that during the War of the Magi, Amdapor's enemies resorted to summoning a great demon from the void named Diabolos. The demon would remain in the ruins of the city until the Calamity weakened the seal. Another demon, Ferdiad, was imprisoned in Amdapor Keep, and was surreptitiously freed due to the reckless acts of the Lambs of Dalamud.
