Giruvegan

Known as the Holy Realm, is a location in the land of Ivalice. It is an ancient city that has faded from the people's eyes, and many have sought to rediscover this forgotten settlement, but to no avail due to the dense Mist that permeates the entire region where the city is believed to be located.

Giruvegan is located in the far south of Ivalice, in the Jagd Difohr region. To reach it, travelers must cross the Feywood. Even then, entrance isn't simple, as only The Gigas may open its gates. Giruvegan appears to be a literal realm located on a different plane; nothing of the Feywood can be seen behind the Gate of the Gigas from the Giruvegan side.

The city does not follow the standards of other cities in Ivalice.
The city consists of a giant pit, at the very bottom of which is the Great Crystal. Around the sides of this pit are platforms, going down the way. These platforms are connected by invisible platforms, that appear only when approached.
The only other way to travel the city is by the many waystones that are all around the city.
Above the city, only accessible by a waystone guarded by the Esper Shemhazai, the Occuria still reside, keeping a watchful eye over all of Ivalice. Never to leave this place, only people deemed worthy may actually see the Occuria.
