Enaran

Star Trek: Voyager
Episode: VOY 148 - Remember

A humanoid species native to the planet Enara Prime in the Delta Quadrant.  A telepathic species, they have an advanced energy conservation technology, although their warp capabilities are not as sophicated. 

The U.S.S. Voyager first encountered the Enarans in 2373 while in the Delta Quadrant.  Although implanting memories in another person is considered unacceptable, Lt. B'Elanna Torres found herself the unwilling recipient of telepathic memories from an older Enaran who wished to transfer them to her before she passed away.  It wasn't until Jessen, a female Enaran engineer, volunteered to telepathically link to Torres, that the truth about the forced memory transfer, as well as Enaran history, became clear.
