Ryloth

Ryloth was a planet in the Ryloth system of the Outer Rim Territories, and the homeworld of the Twi'lek species. Its terrain varied, filled with jungles, mesas, valleys, and volcanoes, and had an atmosphere breathable for Twi'leks and humans alike. A forest covered its equator, filled with dangerous predators. Given the varied and dangerous terrain, Twi'leks lived in caves underground where it was safer.
