Shenshen is the younger sister of Leetah. She is known throughout the series to be useful as a midwife (birthing Ember & Suntop, Tyleet and Mender). She is often overbearing towards her nephew Suntop (most noted in the quest in the Forever Green). She has lived both in Sorrow's End and with Cutter's band during their sleep-time. Shenshen isn't a particular fan of Cutter because of what happened to her when Suntop and Ember were born. She doesn't make a lot of appearences in Elfquest. Although Shenshen seems rude at sometimes, she is actually pretty funny (once you get to know her).
In later years she began travelling with Shuna on her quest to improve relationships between human tribes with each other and with the Elves. By that time the Elves (who already have a low birthrate) were in no hurry to have any children, leaving her bored and restless. Humans have many children, so by wandering with Shuna (appropriately magically altered to appear outwardly human) she could practice her trade while hiding the fact that she didn't age.
