Whicker; 5th Mistress of Umbra.
Still a relatively young Vampyre (Vam-pear) but she has become nearly as powerful as the Elders.

Newborns start out with Blood Red eyes.
As they reach Maturity; learning to control their new bodies and bloodlust, their eyes start to brighten to a pale ghost blue, signaling they are now fully in control

From there, their pupils may take a new shape, and in time they assume a natural color so that they may walk amonst the mortals.

The bottom eye is a mirrored version of an eye icon I commissioned, the one on top is an alternate color just to see what it would look like.
