From publisher blurb:
Two worlds of great natural beauty locked in a struggle that threatens to destroy them both. Thraxis and Arril: blue sisters sharing an orbit, with continents, seas, and life.
A world in the midst of an Age of Majesty many believe will never end: nine diverse Empires at the peak of magical and cultural achievement. A world that has never known an Age of Darkness, where men and women push themselves daily to greater heights. It is an age of innocence and hope, when possibility knows no bounds.
Elder races untouched by the decay of time, great monuments to man's resourcefulness and his hubris. Mystic power waiting to be claimed, and a destiny still in the making. Dragons ruling an empire, a land that can forge gods.
The Canticle of the Morning Star: an inscrutable living Prophecy that is either a warning, or a malevolent force leading mankind towards annihilation.
The world has become a beacon to those who wish to subvert, destroy or command, and they are flocking here, bringing their alien wars in a bid that will alter the course of history and the nature of reality. Celestials, demons, devils, gods, and a sophisticated race called The Strangers compete with men, elves, dwarves and halflings to recast this idyllic planet in their own images.
