Other

An Other is a being with immense power that can exist on several planes of reality and have their own home realm which they are tied to.

Realm
The realm of an Other is a plane of reality created by the Other's power. They are manifestations of the Others and serve as their home realm. Others are linked to their realms so that if they are destroyed, their realms would cease to exist. Realms are often otherworldly and don't necessarily follow the laws of the material plane.

Becoming an Other
Others are either born Others or ascend to Otherhood.

Born an Other
An Other's parents were Others and they inherited the immense power of their parents.

Ascending
This is the way most Others were made, through ascension. There are several ways to ascend into Otherhood but they all require the being acquiring huge powers of power.

The most common way of ascending is by interacting with Soul Stone. Soul Stone is an Aurelian that holds great power and is said to be able to transfer its power into beings who activate it.

Another way to ascend is by eating the fruit of the Sacred Tree. This was hold the Others of Angels were created.
