Arynäe was once the capital of the Ravinian Empire, which was destroyed in the War of the Cataclysm.

The city of Arynäe was ordered built by the Empress Ravinia, soon after her rise to power. Even with the help of the Orenthir, the enormous fifty-foot city walls took nearly eighty years to construct. The city grew around Castle Myrdon, which sat on a large hill in the center of the metropolis.

At its peak near the end of the Fifth Age, the city was the largest in the Empire, with a population of over 100,000. Sadly, the city came under siege during the Cataclysm, and left a smoking ruin.

After the ruins were rebuilt in the early Sixth Age, the city was renamed Alenthas and became the capitol of the Kingdom of Alveron.
