Septisegyai

The Septisegyai is the blanket term used to refer to the Seven Great Realms of the universe, and another other lesser realm, in the world of By the Blade. The Seven Great Realms are known in the order The Earth Realm, The Shadow Realm, The Nightmare Realm, The Dream Realm, The Phantom Realm, The Hollow Realm, and The Elder Realm. These realms are all led by governmental leaders in a hierarchal system, with the exception of the Earth Realm. Each realm is separated from the others and can only be accessed by portals that are established in temple-like structures that are positioned in several places within each realm or by an individual who is extremely skilled in teleportation techniques.

Each realm within the Septisegyai can be treated as its own planet with each realm abiding by the same laws of physics, albeit with a few differences that are usually visible in the respective realm's fauna and population.
