The Galidyn reproduce by laying one egg every century. Each young is cared for by its immediate family, then educated in the Galidyn "school system," usually by an elder Galidyn who teaches history, hunting, mathematics, language, aerodynamics, computers, and medicine. The species has a participatory democracy and all Galidyn who complete their instruction successfully can participate.

The Galidyn once lived in peaceful coexistence with the Fyodoi, the human population of Fyodos. However, many years ago, the technologically advanced human nations waged a terrible war among themselves. The war, now remembered as the Great Cleansing, destroyed human society. The humans abandoned the ruined cities, and instead of rebuilding, shunned technology and slowly regressed to a stone age level.

Nowadays, all attempts to communicate with the primitive Fyodoi have proven futile. With all records of their past expunged, the Fyodoi consider the Galidyn to be heinous, technology-worshipping monsters. In truth, the Galidyn feel sorrow and pity for the Fyodoi, but realize that attempts to re-educate them would be wasted, at least under the current conditions.

Any offworlders spotted with high-tech equipment will be escorted to an open meeting place called the "Crater of Debate," and asked to explain themselves and where they have come from. It is possible that some particularily eloquent heroes may be able to convince the Galidyn to support the Alliance, but the majority of the great creatures will not consent to leave their planet. Instead, they will vigorously defend the planet from any Imperial incursions, as well as aid the Rebels in setting up base on one of the abandoned continents. (Some Galidyn may be pursuaded to venture out into space, provided they are promised intellectual stimulation and problem-solving.)

The Imperials remain unaware of the presence of Galidyn on the planet. When initial probes and scouting parties landed on Fyodos, the Galidyn hid themselves and used their sensor-jamming equipment to avoid detection. Since there are no strategic assets on Fyodos, the Imperials have not established a permanent presence there.
