In the lunar labyrinth,
in the land of darkness...
...في المتاهة القمرية، في بلاد الظلام
Im Mondlabyrinth im Land der Finsternis …

en la tierra de la oscuridad…
En el laberinto lunar,
en la tierra de la oscuridad…

le pays de l’obscurité…
Nel labirinto lunare della Terra dell'Oscurità...
No labirinto lunar,
nas terras das trevas...
В лунном лабиринте, стране мрака...
