The war looms over the world of Errat. The four factions saddle their steeds and sharpen their swords to march to the battlefields. But few, if any, are aware of the shadow that hangs over them.

The horns, worn out from disuse, re-echo from the Peaks of the Night to the Celestial Prairies. Errat is in danger, but nobody knows yet.
