Trill (mirror)

The Trill are a pair of species from the planet $𝜇$. One is humanoid and distinguished by a pattern of spots from the top of their head to their toes, and the other is a symbiotic slug-like organism called a $𝜇$. The symbionts often "join" with a humanoid host so they can experience the universe at large.

The Trill were subjugated by the Terran Empire sometime around the late 22nd century before that their military was the Trill Defense League, the Trill government is the Trill Republic.

Physical features
The Trill are very similar to Terrans except for their spots, which are mostly seen on the sides of their heads. These spots run from their heads down their shoulders and carry on down their torso and legs to the feet because of this the Trill are considered to be almost equal to Terrans.

Other information
The Trill race consists of both hosts and symbionts. The Trill symbiont is a creature which is implanted into a Trill host, and subsequently joins with it, but most of the race consists entirely of unjoined humanoid Trill.
