The setting for the Phantasy Star
RPG series, Algol consists of three major planet
s around a star
not unlike our own. The planets, in original order from the sun, are as follows:
Motavia -- a barren, desert planet, home to the Motavians, a furry, squat, beaked species.
Palma -- the languid, temparate middle planet, home to the human-like Palmans.
Dezolis -- the desolate, ice-encrusted outer planet. Populated by the cranky, elongated, green-skined Dezolans.
There is, however, a mysterious fourth satellite to the system -- Rykros, the invisible planet. In addition to its inherent inperceptability, the planet is also in such a far orbit from the star and from the other planets that it only crosses nearby once every thousand years or so.
