The Theelin are a near-Human species that suffered greatly during the Times Of Chaos, coming to the point of near extinction. Only some tens of thousands of Theelins remain, most in the Outer Rim and many suffer from mutations due to the irradiation of their homeworld during this period.

The Theelin are known to be expert singers and the Theelin Diva, a religious order amongst their species, are famous throughout the galaxy for their excellence in this area.
