The Positive Energy Plane is an infinite, empty, blinding firestorm of life-giving light. Upon entering this plane, an unprepared traveler would have first noticed the sun-like brilliance burning into her eyes, severely limiting the range of vision and only being able to discern nearby beings or objects by the shadow they made in the backdrop of infinite dazzle. As she gasped at a sight not meant for mortal eyes, she would have quickly realized there was no breathable atmosphere to even form a scream. The sudden feeling of weightlessness might not have been cause for concern because almost immediately any wounds would have been healed as the life-giving energy permeated her entire being and then went beyond any sense of wellness she had ever experienced. Infused with power only felt in dreams, she might have briefly entertained the thought that air was no longer necessary as she ascended to godhood, but as her cells reached their capacity, she would have realized in a fleeting moment what it means to be mortal before exploding in a burst of radiant energy.
The Positive Plan is the source of all energy and matter in the universe. It is also the source of all life, it is the Cosmic Fire at the heart of the multiverse that gives birth to mortal souls. The plane has no surface and exists as an emanation of life-giving energy radiating from an incandescent interior that resembles the molten heart of an active star.
Little is known about the creation of souls, and their transit to take hold in a mortal body, the but they are thought to be ejected through a similar process as the Pillars of Creation, through naturally occurring rifts between the domains that align with significant features of raw energy in the The Material World. In the case of the Positive Plane, it is thought that every star is an outflow of pure energy from the Positive Plane.
