- The Trill planetary government has no name given in either canon or licensed non-canon material. The name was coined by fanfic author StarSword, with the initials first given in "Tinker, Golfer, Doctor, Trill" and the expanded form used in "The Silence Ends".
The FST opened diplomatic relations with the Federation in approximately the 23rd century and were members by the mid-24th century. (Bait and Switch: "Tinker, Golfer, Doctor, Trill"; Star Trek: The Next Generation)
