Positive Energy Plane

From Manuel of the Planes (3e):

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 mortal eyes to comprehend. 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.

The greatest immediate danger on the Positive Energy Plane is the plane itself. Its radiance poses a threat to travelers who go there.

There is no air in the Positive Energy Plane. While the plane is not a true vacuum (the positive energy provides the equivalent of normal atmospheric pressure), suffocation is a great danger. Even the fast healing given to all inhabitants of the plane has no effect on suffocation. Travelers on this plane must bring their own atmosphere or forgo breathing while here.

Similarly, food and drink do not exist naturally on the Positive Energy Plane, and subdual damage from starvation and thirst is not automatically healed either.

Just as the Negative Energy Plane is divided into major and minor areas, so too is the Positive Energy Plane. A traveler may suddenly find herself in an area where her ears ring, her muscles quiver, and even her bones throb from the sudden surge of energy. But there is no immediate clue just how the border shifted, and no way to know which way lies minor positive-dominant ground. Spells such as safety help the traveler, but such energy fluxes are always a risk.

The plane of positive energy is a place of brilliant white, where the inherent power of the plane bleaches out the spectrum and leaves an environment of nothing but white and stark shadows.

Clear vision (including darkvision) is limited to 5 feet. Objects and creatures beyond that range appear as indistinct blots of darkness against the background white. Distance is impossible to gauge within this brilliant environment.
