Meliora

"The Heavens Above," speak many and most religious texts. It is not an inaccurate phrase, even if the planes associated with Meliora lack any truly distinct location in the realms, given their close relationship with the Positive Plane and their source of all things good, which have long been depicted as descending from above.
What I would give to see what that holy place must be like. To bathe in the light of the sun of all suns. If only I could be so grossly incandescent.
Praise the Sun.
-Unknown Sun Worshiper

Meliora is not a distinct place in reality, any more than Realmspace (Material Plane) and Wildspace. It is a term used to categorize the seven heavenly realms: Arcadia, Arborea, Beast Lands, Bytopia, Elysium, Mount Celestia, and Ysgard. That is, of course, not counting the Positive Plane itself, but that place exists in a way that no mortal knows or can know.
Melioran realms can easily be identified by the heavenly glow they shed into surrounding wildspace, and the comet-like trails they leave in their wake.
