The town of Krowatol was once known as an oasis in the middle of a great desert, a beacon of hope for weary travelers. Now its water supply is almost entirely gone, and the town is as dry as the landscape surrounding it. When two mysterious travelers arrive, Krowatol resident Rosé Tomas discovers that they are the infamous alchemist duo known as the Elric Brothers Edward and Alphonse. As word of their arrival reaches the town's governor Arzen, the brothers are invited to his estate to hear out Arzen's strange and dangerous request.
