Gaelahesta

Gaelahesta (ガエラヘスタ, Gaerahesuta) is the holy city that isn't affiliated with any of the 3 major countries of the Underground World.

Description
Gaelahesta is said to be a majestic city that is comparable in size to Midhaze. Despite its splendor, few people live in it, as most of the people in it are pilgrims from either Jiordal or Agaha, who seek to learn about the gods. Due to its neutrality, the visitors from other countries are forbidden from fighting each other, as a War-Free Covenant prohibits any conflicts between the inhabitants.

In the center of the city, which is spread out in a circular shape, is where the Everastanzetta, Institute of the Gods, is located. The War-Free Covenant prohibits any conflicts except within the castle of Everastanzetta.

Everastanzetta, Institute of the Gods
A holy castle that was bestowed by the gods to the pious draconoid believers for them to host the Selection Trial and research ancient knowledge of the gods.
