From publisher blurb:
DRAGONS OF PURE MAGIC
The true dragons are broken into numerous groups, each organized around a single common set of concepts they embody. The Chromatic Dragons are all organized by color. The Metallic Dragons are all organized by ore. The Imperial are organized by regions of rule, the Primal by elemental planes and related dimensions. All are creatures of powerful magic.
But none are creatures of pure magic. None are defined by what school of magic they embody. None, but the Draconis Arcanus.
Eight new forms of True Dragon, each embodying a single school of magic, from the defensive Abjuration Dragon to the ever-changing Transmutation Dragon, these are true dragons of pure magic, aloof and infused with arcane might in a way no other dragon can challenge. Each is presented with all the information needed for all twelve age categories, and three full stat blocks.
Also included are numerous Spell Dragon templates, allowing a GM to add various magic descriptors to allow for Chaos Infused spell dragons, or Druidic Spell Dragons.
Your players may think they know magic; that they know dragons ...
How Wrong They Are!
