In 1289 AH (1880 in Gregorian calendar) the Empire of Yntheras is struck by an unknown enemy ; they invade the whole country and only those who lived behind the kingdom's walls have been protected by the assailants . Four children , Zayn , Elmeeria , Enes and Yynil are outside of these walls . Far away from the place where a bit of security seems to be a promise , they take route to reach the walls . Will they survive the war that rages in the empire , or will they succumb under their weak bodies ?
