Verin Mathwin is character from the Wheel of Time series of books by Robert Jordan. She is an Aes Sedai of the Brown Ajah. She has some graying in her hair - a sign of not inconsiderable age for an Aes Sedai. Like all Brown Ajah, she devotes herself to knowledge and the pursuit of it; as a result, she has a tendency to ramble when talking about a particular subject or become lost in thought.
Verin's scatterbrain tendencies hide a calculating mind that is more aware of events in the world than she lets on. Speculation of whether she is Black Ajah is rife in fandom.
