In an alternate timeline, Annorax of the Krenim uses temporal technology to remove the Rilnar from existence. As a result, a plague destroys most of the Krenim race. Annorax begins his two-hundred-year attempt to resurrect his people. (VOY: "Year of Hell", "Year of Hell, Part II")

In an alternate timeline the planet Gaia is colonized by the crew of the USS Defiant who had been transported through time. The ship crashed on the surface and was unable to send a distress call, as communications through the Bajoran wormhole were not possible at the time. (DS9: "Children of Time")
