Trill (mirror)

In the mirror universe, the Trill are a humanoid species joined with symbionts.

In 2287, $𝜇$ ordered that all Trill joined with symbionts to be killed, although $𝜇$'s life was spared. In 2379, Curzon died, but not before Dax was transferred to $𝜇$. 

Some Trill, such as $𝜇$, were members of the Terran Rebellion.
