Estya. Where magic runs through the veins of every inhabitant just as it runs through the world itself, from the divine, to the synthetic, to the perfectly balanced Light and Dark. Where a single soldier with a single number, their Blood Number, can raise or raze entire nations in mere days.
  Fallis knows this all too well. With a Blood Number of Light Seventy-Four, she is the Ebonblade's ace up their sleeves; the most powerful Light sorceress still alive. Despite this, treachery's deep roots snake throughout the Ebonblade's ranks, and Fallis finds herself trusting a shadow on the battlefield more than her own brothers-in-arms. How far she will follow them, however, remains to be seen. Probably just to the border and to safety... possibly through the gates of Hell itself.
