World of Teiramyt
Started in Civilized Year One and led by Railiss, the Eladrin Empire spanned from most of the continent of Fomoraig to Brythonia and Laetinus. This empire was the longest-lasting of any empire known to Teiramyt, spanning over 500 years. The empire was friendly with most other races, though their land was vastly composed of Eladrin. Any immigrants were also generally considered lower-class citizens, but Elves were treated better and a few Elves, such as Carothis Felaryn, became leaders in the Eladrin Empire.
By year 432, the Eladrin expanded to control the entirety of Fomoraig. King Vallian soon after declared fullscale war on the Drow race that had been disrupting their civilization. The drow typically raided Eladrin settlements from underground. But the Eladrin had chased away most of the Drows when the empire took Fomoraig, forcing them to the mostly desert continent of Medinan. But the Eladrin decided to expand and moved into the desert continent. In 438, the fullscale war, known as the First Fey War. The war was a complete failure; the Eladrin armies were poorly equipped to handle desert warfare. The war was primarily focused on the control of underground Drow tunnels. But the Eladrin struggled and by year 498 of this lengthy conflict, their armies were vastly depleted, and 85% of the forces sent to Medinan were killed. The war was mostly abandoned by 504, though the Eladrin still held a few tunnels. But by 517, the Drow mounted an attack on the Eladrin Empire. Slowly, their armies (built up over a hundred years of being cast away in the desert) took major fortifications and settlements in Fomoraig. The Eladrin were forced to abandon the continent, and the entirety of their empire eventually moved to Brythonia and Laetinus. But their empire was weak, and the Drow were ready to challenge them. By 530, the Drow moved to Laetinus and then to Brythonia taking those continents as well. The Eladrin retreated to the Northeast side of the continent, where they banned together with their Fey brothers, the Elves, and stopped the Drow from completely exterminating the Eladrin race from Teiramyt. But by this time, year 541, the Eladrin Empire was no more.
