Darkness descends over Ardjia, that newly discovered beautiful gemlike planet and its many hundreds of  starlane jump points that the Syndicate, the Identic, and Ardjia herself are all too willing to commit murder to control. What is the darkest sin of a world of dark energy users? Where blood is the currency of truth, of power, of life itself, where living sacrifices have their hearts ripped out and offered to the gods atop ancient pyramids, what could possibly be considered a dark blasphemy? Lord Lightfall and the undisputed King of Sunset Highland face their own darkest sins while trying to stay alive and bring the dark ka culture of Ardjia up out of the gravity well and out into the Intergalactic Identic all the while trying to maintain a bit of integrity amidst an array of awful choices whose consequences may come to affect millions on Ardjia if not billions throughout the Identic.
