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
According to Evileye, it is said that the city was built five hundred years ago by the Eight Greed Kings, to be their capital when they ruled the continent. Although the Eight Greed Kings destroyed themselves and their nation through internecine, 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 magical items from the era of the Eight Greed Kings to assist them on their journey. 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 they wonder whether or not information about the Death Knight they captured can be found there.

Layout
According to hearsay, Eryuentiu has a metropolis existing under its shadow. The metropolis is entirely surrounded by a magic enchantment, such that people cannot imagine that it is actually 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.
