In an Alternate version of Equestria, the battle against storm king is a bit like ww2 pacific. Sky Beak is the captain of the Jolly Rogers, during one of his missions, something happened to him which caused him to quit. Years later, his son Terramar wanted to follow his footstep to become a naval pilot. Sky beak soon became concerned about his son's ultimate fate of dying on the battlefield. Can father love change Terramar's mind?
