Bryyo is the second planet visited in the Federation Solar System and the closest to the system's sun. It was once the location of an advanced civilization, the remnants of which is the corrupted Reptilicus race that still lives on Bryyo. Bryyo's importance is based on its waste fuel resources. Elysia is the third planet in the system and was where the mystical Chozo once lived. This cloud planet is important because of the sky facilities hovering in its atmosphere. The technology is used by the Federation for research and information gathering.
