The Oneiric, is one of the Planes of Existence. It is the fifth Plane in the chain of Planes. It is between the Oneiric Plane and the Bright .
The Spiritual Plane is a layer of the universe without the interference of the desire for advancement, progress or even the desire to build technological civilizations. It is a layer and version of the universe in which there is no exploitation or abuse of resources, being a completely natural and vivid Plane.
Spirits
Spirits are immortal beings native to the Spiritual Plane. They are born and appear in the most varied shapes, sizes and appearances possible. The Spiritual Plane is a place so focused on natural life that these beings are simply born.
Spirits share the mentality of the Plane, having no desires or ambitions for material wealth that would make them exploit and destroy the world in which they live. However, this does not mean that there are no evil Spirits. The only difference between these Spirits and other beings is that they do not need clear motivations such as money or land to oppress and kill. When a Spirit does these things, it is because he enjoys it; it is as simple as that, that is his vision and mentality.
Spirits range from the small and harmless ones that wander randomly through the naturally rich vastness of the Plane, to those called Great Spirits, the latter having great influence and authority, whether in the Spiritual Plane or in the Mortal Plane, as some of them become sources of worship for mortals. For this reason, Spirits are the main rivals of the gods of the Ethereal Plane, even though they are theoretically on a more distant Plane, making their influence on the mortal world more difficult.
