Reles is the capital city of Spintir. It is the only major settlement on the planet. While the outlying areas harbor farmers and much of the poorer populous, the inner city is one of culture. A large open bazaar offers goods from all throughout the Galaxy, and the Museum of Spintir is a regionally famous location that displays many ancient artifacts.
The Empire does maintain a small presence here through a garrison of Imperial soldiers, however as the planet does not offer very many natural resources it isn’t considered to be an important world for the Emperor.
