Outside Realm...

This vast land is called the 'Outside Realm' because it originates from beyond this realm.

The reason why the 'Outside Realm' came to the Initial Realm is unknown, and it is filled with endless mysteries.

Within the Initial Realm, there are hidden great secrets, and besides the Primordial Star within the Mortal Dust Forbidden Land, most likely, more secrets come from the depths of the 'Outside Realm'.
