Trill is the homeworld of the two species jointly known as the Trill. The planet has a blue-green sky, and the rocks are bluish in tint.



Trill's first contact with alien life was in the early 21st century, when a Vulcan ship landed, proposing friendship and cultural information exchange. Trill society was deeply divided by this development, with many fearing the outsiders represented a threat to the symbionts. The ruling council eventually allowed for limited contact with Vulcans, but no other alien races. This first contact also led to increased security around and secrecy regarding the 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. (DS9 short story: "First Steps")

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. (novel: Articles of the Federation)


In the 21st century, Trill was governed by a ruling council, composed solely of joined Trills, and primarily males. The council was lead by a head councilor, addressed as "Mr. Speaker". The council met in the council chambers, at the time one of the oldest and largest spaces in the capital city, adorned with acelon desks and capped by an opaque dome. As early as the mid-21st century, debate raged over abandoning the historic chamber for more modern building. (DS9 short story: "First Steps")

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. (DS9 novel: Trill: Unjoined)


The largest mountain range on Trill is known as Ayai'leh-hirh. The largest mountain is Bes Manev.

Trill is an M-class planet and homeworld of both the Trill race and the non-humanoid Trill symbionts.

The planet Trill may sometimes be referred to as "Trillius Prime" but this has not been firmly established in canon. The Star Trek: Excelsior novel, Forged in Fire, posited that "Trillius Prime" had been coined by a non-Trill scientist and that "Trill" was the indigenous species' preferred name for their homeworld.

Aumil Killan is a Trill government official working and living mainly on the planet Trill. (Star Trek: The Cantabrian Expeditions: "Catalyst, Part One", "Thicker Than Water")
