The Celestial glides through the inky blackness of deep space when it suddenly finds itself in the midst of a violent attack. Captain Shirakaya, a powerful sorceress, is the dauntless captain of the Celestial, and she and her crew just barely escape the murderous barrage.

But now they must bring unsettling news to the Ruzurai, the ruling Tal'manac Order. Shirakaya is convinced the attackers were none other than the koth'vurians, a war-hungry race that had been exiled eons before.

However, the crew's harrowing tales are met only with skepticism. The Ruzurai turn a blind eye to the growing threat, and to make matters worse, Shirakaya's magical powers are mysteriously weakening.

As the body count rises, Shirakaya struggles to convince the galaxies that the koth'vurians are back-and this time, their mayhem threatens to engulf the entire Ensar universe.

As her magic continues to fade, Shirakaya is faced with a hard question: How far is she willing to go to vanquish this ancient and monstrous race and see peace prevail?
