Cephiro is the world the three girls are summoned to and at times it
seems to be a character in itself. Its landscape and the behavior of its inhabitants
change to reflect the state of its Pillar. Cephiro is a mystical, otherworldly
realm, not a parallel universe or imaginary dimension, but a real world with
its own physical laws. It's hard to tell whether the "country" of Cephiro
is a planet revolving around a star or a sort of asteroid body floating in
space. Cephiro is a utopian land which the Magic Knights are there to save,
but it is not always their ally. The monsters of Cephiro, born out of its
inhabitants' fears, must be defeated or won over by the three girls.
In the second season there are three other worlds, sometimes referred to as "countries", whose inhabitants visit Cephiro: Autozam the technological, Japanese-like land (green color scheme), Fahren the Chinese-like land (red color scheme), and Chizeta the Arabian-like land (orange color scheme). During the second season there are many shots of Cephiro from space that would suggest it is a planet. In any case, Cephiro is a dynamic realm that responds to the will of its inhabitants through its climate, landscape, and even its natural - or unnatural - creatures.
