Dragon, True

True dragons are generally divided into four broad categories: chromatic, Imperial, metallic, and primal. However, a fifth category of true dragons has emerged known as planar dragons. 

Planar dragons (adamantine, anarchal, arboreal, axial, beast, concordant, hellstorm, radiant, ruin) epitomize the alignment of the outer plane they call home. Planar dragons use Dragon Age Category, Dragon Ability Score, and Dragon Attack and Speed tables found in the Pathfinder Bestiary, and additional dragon rules presented there.
