Like a dome above the other planes, the Positive Plane is the source of radiant energy and the raw life force that suffuses all living beings. Like the heart of a star, it is a continual furnace of creation, a domain of brilliance beyond the ability of mortal eyes to comprehend. It is a vibrant plane, so alive that travelers are empowered by visiting it.
The Positive 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 can’t handle it for long. Only creatures that have Immunity to Radiant damage can survive there.
Vibrant life, creative energy, and radiant health are the essential characteristics of the Positive Plane, though touching this fundamental energy can be just as dangerous as entering the soul-siphoning annihilation of the Negative Plane. Characters who survive an excursion into the Positive Plane often find that it leaves them with a lasting charge, making it hard to calm down, to stem the flow of ideas, and even to sleep. On the other hand, they also find themselves with a persistent resistance to disease and despair.
