Aeris

Aeris is the kingdom built by the Creator for him and the other Legends to live in. It is a part of the Other Universe, but sits on a higher plane of existence than all the other worlds. The Creator is the only one capable of travelling to and from Aeris, while other Legends remain in the kingdom unless they choose to descend to the mortal planes. Aeris is analogous to the kingdom of Heaven in Christianity, but there is no indication that the righteous souls of the dead in the Other Universe go to Aeris or any other afterlife.

Structure
Aeris is described as a vast city made of sparkling white stone. The city is circular in shape and is made up of eight cocentric circles that gradually rise higher up to the central level where the Creator's palace stands. Originally, the city was divided into four segments: the Creator's central tier and three equally divided regions governed by Astrum, Terrum, and Fatum, respectively. Following the War in Aeris, most of the city and its inhabitants were wiped out. The Creator rebuilt the city as it currently stands with himself as the sole governor.
