Timor was a Trill who labored in the Caves of Mak'ala to care for the Trill symbionts as a member of the Order of the Guardians. (DS9 episode: "Equilibrium", New Worlds, New Civilizations short story: "Aversion", DS9 novel: Trill: Unjoined)

In 2371, Jadzia Dax consulted with Timor over hallucinations she had been having. Timor informed her that they were actually memories of a past host, although he was not able to determine which one. When Benjamin Sisko and Julian Bashir questioned him later, Timor had changed his story, probably due to pressure from the Trill Symbiosis Commission. Timor later guided Jadzia to the pools where she could bring forward Joran Dax's memories. (DS9 episode: "Equilibrium")

Rantic Lan was Timor's apprentice. (New Worlds, New Civilizations short story: "Aversion")

When Bashir and Ezri Dax visited the Caves of Mak'ala in late 2376, Timor was not among the Guardians present. Bashir wondered if he had been dismissed or transferred for helping Jadzia five years earlier. (DS9 novel: Trill: Unjoined)
