It is power incarnate. It is radiance beyond compare. It is life realized to the fullest.
The Positive Energy Plane is best compared to the heart of a star. It is a continual furnace of creation, a domain of brilliance beyond the ability of monal eyes to compre- hend. Its very being wavers and ripples as new matter and energy is born and swells to full power like a bursting fruit. It is a vibrant plane, so alive with itself that travelers themselves are empowered by visiting it.
The Positive Energy Plane has no surface and is akin to the Elemental Plane of Air with its wide, open nature. However, every bit of this plane glows brightly with innate power. This power is dangerous to mortal forms, which are not made to handle it.
Despite the beneficial effects of the plane, it is one of the most hostile of the Inner Planes. An unprotected character on this plane swells with power as positive energy is force- fed into her. Then, her mortal frame unable to contain that power, she immolates as a small planet caught at the edge of a supernova. Visits to the Positive Energy plane are brief, and even then travelers must be heavily protected.
