Yedrin Dax was a host of the Dax symbiont in an alternate future timeline created by the starship Defiant's crash landing on Gaia. He is the great-grandson of Jadzia Dax and Worf. His existence was erased when the Defiant avoided the crash and that timeline was averted. (DS9: "Children of Time").
It is assumed Yedrin will never exist, as Jadzia Dax died before she could have a child with Worf.
- Yedrin was played by Gary Frank.
