See not the dimly lit, cramped room, before you. Instead, imagine entire oceans, vistas, entities, and civilizations. These lie in separate planes from our own— but exist there before us nonetheless.Planes are lenses of existence— each concurrently extant within the same space, at the same time. Different beings live within each plane. While some are able to see through multiple— the perception of others may be limited to theirs alone.
There exists an uncountable number of planes, and so, most focus on the primary four. These four planes are some of the largest, and most relevant within one's daily life. The four primary planes are as follows;
The MaterialThe Material plane is where humanity and the world familiar to them resides. Most among them are limited to this plane, though some are able to gain insight into the others around them, either by witnessing entities from these planes, transcending, through ritual, or myriad other means. The Material plane is perceived from birth.
The AscentThe Ascent is a higher plane, within exists many gods and ascendent beings. Uniquely, the Ascent consists of existential levels, an entity may exist only within the first level— while another, possessing great insight, may exist within the fourth. The Ascent is perceived merely by gaining insight. Those who delve into the occult will inevitably be able to perceive it.
The DreamThe Dream is created from the collective minds of sleeping entities, from the lowest creatures— such as humans, to eldritch gods. The dreams held within are not connected to one another— at least, not at first. One must undergo purposeful effort to combine dreams. The Dream is perceived in one's sleep.
The AbyssThe Abyss is a mirror of existence. Every plane— from the Material, to the Ascent— is reflected within the Abyss. The reflections within are twisted, and dark. Like the Ascent, it contains existential levels within itself. The Abyss is easily perceived by gaining insight— or by staring into the dark.
There is one thing you must remember; no matter what plane you inhabit— you are nothing. You are weak. There are beings who could destroy you with a single thought— even here, in our own material plane. Never forget this, do not grow arrogant simply because you perceive more than your peers.
