Septerra is a unique planet system. Imagine
a world where seven continents or shells, Shell I-VII, float freely
in space, one
above the other.You can even
look down from the edge of one continent and see the one below.
But it's not easy for the inhabitants to travel to other shells.
Thus, many different cultures and individual landscapes have developed
since the creation of the planet. The Septerra Core story is as
unique as the world in which it takes place, because it simply couldn't
happen anywhere else in the universe.
