Dyvien (topic title not long enough)

Name: Dyvien (pronounced 'dee-VY-enn')

Gender: Female

Species name: Kinfel

Description: What looks like a bipedal feline-related animal. She has strong, toned legs perfect for running and jumping. Her arms are strange, turning into powerful, twisted claws where usually her species would just have relatively paw-like hands. Her tail looks like some kind of raptor dinosaur's tail, tapering towards the end.
A magnificent pair of wings extends from her back, white and glowing. There is a dangerous air about her, however. Even when the halo she always keeps with her is sitting atop her head, making her look like some kind of fabled seraph, there's still a strange feeling emanating from her that you can't quite place. Her eyes are white, though they're shaded in the centre where her pupils would be.

Other: Dyvien is cold and unfeeling. Upon first a first encounter, she will attempt to drain the life from victims via tearing at their soul and drinking all the energy that she can. Separating her from her halo weakens her the further away she is and the more objects are in the way, but your characters won't automatically know this, and they'll need to figure this out on their own.
Unfortunately for her, Dy slips up in battle a lot. Her halo isn't attached by anything, so she loses grip on it often.
