Some pronounce it, nee-moo, which I think is not so pretty and too close to Nemo, but the pronunciation, nih-moo-way is sweet. I like the combination Elora Nimue -- VERY magical!
There is more out there in bardic legend about Nimue and her time spent with Merlin. As I recall, she meets Merlin when she is only a girl when he is visiting her father's castle and she becomes enthralled with the much older man based mostly on the magical training he can offer her. After years of begging him, she convinces him to take her on as a student and despite himself, Merlin, over time begins to fall in love with her. She sees her power over him and decides to use it to seduce him into giving her the last secret he has refused to share up to that point to give her. I can't remember what the actually secret was. But anyway, she puts him in some kind of trance while they're laying in the forest together and causes him to tell her. After that, she abandons him and goes off to use her magical skills for personal gain and power over men. Supposedly, she is the only woman Merlin ever loves and even though she turns to less than moral pursuits, he never stops loving her.
Nimue is a little-known character in Arthurian legend but she personifies the seductress, a parallel archetype to Delilah in the Bible.
I've only very recently come to enjoy the name after seeing "Nim's Island" and being reminded of the beautiful sounding Nimue. Such a soft and whimsical little gem that I am fast falling in love with!
This was one of my cats' names. I adore it. The name Nimue evokes a sense of innocence for me. While I'd love to see it used, I'm not sure if it would age well. It's a very child-like sounding name in my opinion.
