You have to retrieve the Star Wards that 
have lost their power from the labyrinth,
عليك أن تسترجع حرّاس النّجوم
،الذين فقدوا قوّتهم بفعل المتاهة
Sammle die „Sternenjungfern“ in den
Dungeons ein, die ihre Kraft verloren haben,
Recupera a los Guardias de las Estrellas
que perdieron su poder
Recupera a los Guardias de las Estrellas
que perdieron su poder
Tu dois récupérer du labyrinthe
les sceaux étoilés éteints
Dovrai recuperare dal Labirinto
i Guardiani Stellari che hanno perso i poteri,
Deve recuperar do labirinto a
Proteção das Estrelas que perdeu o poder
Ты должен снять с лабиринта
утратившие силу Звёздные чары
