In a Galaxy across the empty vastness of space, a race of anthropomorphic fox-like humanoids called the Seiran have been locked in a several hundred year war with a race of genocidal brain slug parasites called The Ankarii. The Seiran had kept them at bay but as of three months ago, The Captain of the Imperial Knights, the most skilled and talented warriors in the Seiran Empire's military turned traitor and sided with the Ankarii, taking with him the majority of the Knights! All that remains of this once powerful caste of soldiers is Terrid Aladasair Korvo, the youngest of the knights at 28 years of age. Charged by the Empire's immortal liege, Terrid sets out on the newest Vessel in the Imperial Fleet, "The Seleucia" to hunt down the Traitors before they can let in the Seiran's long time enemy to cause untold casualties.
