Eryuentiu

Eryuentiu (エリュエンティウ) is a 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, the city was all that remained of their legacy. Though the nation built by the Eight Greed 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 and 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.

Chronology
Eryuentiu is mentioned by Fluder's acolytes when wondering whether or not the information about the Death Knight can be found there.

Layout
According to hearsay, Eryuentiu has a metropolis city existing under its shadow. While so, the metropolis city is entirely surrounded by a magic enchantment, such that people cannot imagine it is in a desert. In addition, to this magic enchantment, the floating city can generate an unlimited amount of water, offering its bounty to the metropolis below.
