The Living Realm is a plane of existence where all of the living souls reside during their time while they are alive.
The Living Realm is the realm where souls that have not lost their lives reside in. The Living Realm consists of many planets, galaxies, solar systems, and the ever expanding universe.
Once a being living in the Living Realm dies, their soul is sent to the gates of the Heaven Realm to be judged by the Angel Petr to see if their soul was good enough to enter the Heaven Realm. If the being is deemed unworthy they are sent down to the Hell Realm to be punished for their sins.
