Trillius Prime - Class M - United Federation of Planets
Native Species: Trill, Trill symbiont
Location: Trillius system, Alpha Quadrant
Trill is an M-class planet in the Trill system. It is the homeworld of two sentient species, the humanoid Trill and the non-humanoid Trill symbionts.
Circa 2063, Trill was visited by the L'Dira. Trill's refusal to deal with the unknown race led to an attack on the planet, killing over fifty. This tragic error in understanding convinced the ruling council to increase their knowledge of the galaxy.
The planet joined the United Federation of Planets some time around the early 23rd century; before that the planet's military was the Trill Private Service. (TNG novel: Intellivore) Madza Bral, a Trill politician, was elected Federation President not long afterwards.
By the 24th century, Trill government was run by a President and a Senate, both housed in the Trill Senate Tower, in the city of Leran Manev. That government nearly collapsed when a terrorist attack killed or seriously wounded thousands of symbionts, including that of the president, Lirisse Maz. The Maz symbiont was successfully unjoined, and Lirisse Durghan was able to maintain her position.

Hosts and Symbionts
The hosts, as they are called, are humanoids that appear much like humans, except with distinctive black or brown spots visible from the top of the head, down each side of the face and neck, and down across the shoulders and the sides of the chest, thighs, legs to their feet. Their hands are noted for being unusually cold to the touch. Trill are strongly allergic to insect bites, because the toxins interfere with the biochemical connections between host and symbiont.
The symbionts are helpless, worm-shaped lifeforms who contain the memories of their previous hosts, and who inhabit the abdomens of the humanoid hosts. When a host and a symbiont are joined, the resulting individual is considered a new being. When a host dies, the symbiont is transplanted into a new host. Ninety-three hours after the joining, the host and symbiont are completely interdependent, but up to then, the joining may be reversed without killing the host. A symbiont who is neither implanted into a new host nor returned to their habitat (pools of nutrient-rich liquid on the Trill homeworld) will quickly die, as will a joined Trill host within one to two days of the symbiont being removed. In rare cases, Trill symbionts can be joined with non-Trill humanoids, but the differences in biology means the results are often unstable. Commander William Riker was briefly joined to the Odan symbiont so that Odan could complete peace negotiations, and to keep Odan alive until a new Trill host could arrive. While this effort saved Odan's life, it nearly caused Riker's death.
It was originally assumed that only a small fraction (0.01%) of the Trill population was capable of being joined, a myth that the Trill government continues to perpetuate. This is because the joining of the Dax symbiont with the host Joran (Curzon's predecessor) was a disaster - Joran was insane and a murderer. Joran's joining with Dax was covered up and all records of it were erased. The Trill government attempted to blame the failure on Joran's unsuitability as a host, but the truth was that Joran had passed the host screening tests and was technically a stable host - as was almost half of the Trill humanoid population. The government dares not let this information become public, lest the symbionts become a commodity to be bought, sold and fought over by the public; as long as it is widely believed that only a small fraction can become hosts, the government reasons, then such widespread hysteria can be avoided.
A joined Trill is known by the given name of the host followed by the name of the symbiont: for example, when Ezri Tigan was joined with the symbiont Dax, her name became Ezri Dax.
Trill society has a taboo against resuming relationships with loved ones from one's past joining, on the principle that each life must be unique. This taboo apparently does not extend to non-romantic relationships (or perhaps non-Trills), since Jadzia Dax renewed Curzon Dax's friendship with Benjamin Sisko and others without comment, as Ezri Dax renewed Jadzia's friendship with the crew of Deep Space Nine.
