Location: the God Realm

The God Realm: home to the gods, and to a certain other species. What is this species? Humans. Yes, us mortals are a little portion of the God Realm.

God Realm
The God Realm is a messy place. The oh-so-famous Greek gods take the spotlight there, but there are others that gambol about there. Some famous name include Yahwehjevohahallah, Ra, and Horus. Then there are the gods who haven't gotten themselves into a religion: Blaetheus, Deviletheus, and the God of Disturbing Evil Monstrosities.

Human Realm
Let's feel honored: the most commonly used portal to the human realm existed in Greece at the time of the Greek empire. Had the main portal been somewhere else, we might have ended living in the Quenti Realm, or the Shadow Wings Realm.
