Timor was a male Trill and Guardian in the 24th century on Trill. He worked in the Caves of Mak'ala where he monitored the symbionts' environment, the pools. He noted that the symbionts were very particular about their environment. Like other Guardians, he was a bit awkward with visitors.
During his time there in 2371, Timor met Jadzia Dax, and, without her introducing herself, knew she was joined with the Dax symbiont. Furthermore, he could tell she was "out of balance" with it and was having recurring dreams. He helped her identify their source as stemming from the memories of one of Dax's previous hosts. Timor was initially eager to help the symbiont and Jadzia, but, after pressure from the Symbiosis Commission, which was engaged in a cover-up regarding the previous host Joran Belar, he became less helpful and resisted persuasion from Benjamin Sisko and Julian Bashir.
