This isn't really significant, but she played a very minor role, mainly there to show the reader the effects of Rand al'Thor's ta'verenness.

She had the potential to become an Aed Sedai, however she did not apply herself to the work and was subsequently sent from the White Tower. It is believed Lanfear used Else's persona as a disguise when she infiltrated the White Tower (first quarter of Book 3).

Since then, Else has not been part of the story.
