Eryuentiu

Eryuentiu (エリュエンティウ) is a floating city of the Eight Greed Kings, located in middle of the desert far to the south.

Background
Five hundred years ago, it is said that the city was built to be the capital back when the Eight Greed Kings ruled the continent according to Evileye. After the Eight Greed Kings fell into civil war with each other, this city is all that is left of their legacy. Though the nation built by these kings is gone, the city itself remains inhabited by thirty guards armed with overpowered magical weapons.

Two hundred years ago, the Thirteen Heroes visited the city. They were gifted with magical items from the era of the Eight Greed Kings to assist them on their journeys. Fluder Paradyne had also journeyed there, but was denied permission to acquire an item of his own.
