Multiple realities
(covers information from several alternate timelines)

The Garenor were a Delta Quadrant species residing on a planet located near Krenim space.

In 2374, Annorax utilized his weapon ship to completely erase the Garenor from history, in an attempt to restore the existence of the Krenim colony at Kyana Prime. Annorax's calculations were thrown off by the temporal field being generated by the starship Voyager however, and the erasure of the Garenor had the effect of reverting the Krenim to a pre-warp state. The timeline in which these events occurred was negated when Annorax's weapon ship itself was erased from history, reversing all of the damage it had done to the timeline.

This species was only mentioned in dialogue.
