This is the universe in which most if not all my stories will take place, how these realms are placed indicates the inhabitants of these realms overall power compared to each other. The creation of portals allow the ease of Realm travel throughout most of the universe. There are ten mortal realms overall however what awaits above them all is a place both revered yet unknown.

At the bottom we have the 8 Lesser Realms, called so because they were created after the two realms above them and are considered to be inferior to them in terms of power. Recently, they united their forces under the banner of the Phyurahn Empire, in their goal of traveling to the realms above their own. Information about each individual realm will come soon...

Above them is the realm everyone is familiar with, Earth; or what the 8 Lesser Realms call Terralpakardia. It is designated as the fabled heart of the universe itself and the origin of all the mortal races below it. No one from the 8 Lesser Realms have ever lived to tell what Earth's inhabitants are truly like, as an impenetrable void keeps this realm distant from the realms beneath it from traveling via portal. Anyone who tried with your standard portal will be obliterated by the force needed to travel there and once they fail to get that necessary power, they would freeze in the endless dark void.

The final mortal realm is one highly debated to be considered one at all, Heaven the realm of the Angels. The reason for the debate is because it is the realm where the gods of the whole universe reside, hidden away in the highest sanctum of the realm above its inhabitants where they can observe the whole universe in safety. Despite its distance being greater than Earth's with the only way to ascend to that realm would be through Earth, the Lesser Realms know more about Angels more than they do Earth's inhabitants, even if their information is inaccurate and incomplete.

Universe concept by me.
