A desolate sand sea glimmering in golden light stretches as far as the eye can see. Albaz and Ecclesia press forward through the harsh terrain, slowly forging a bond through their shared journey. But soon, their journey is cut short by a surprise attack from flying machines. These steel-bodied beings, animated with hearts of soot, are the Springans—the treasure hunters of the Great Sand Sea. By a twist of fate, Albaz and Ecclesia ran into the very group they came seeking. They board the Springans’ mobile fortress, the battleship “Exblowrer,” where they meet Kitt, a brilliant inventor and younger sister of Ferrijit. Kitt introduces them to the Springans’ leader, Sargas, and Ecclesia pleads for Albaz’s protection. But Sargas decides to present the duo with an unexpected challenge.
