Vivian looks much like Evie, with "eyes like streams of melting snow," short light blond hair, and a build like Evie's. She is also said to have a pretty face.
Vivian is the cause of the unexplained death of many paranormals in the first book.
Vivian is the only other Empty One besides Evie. She was created by the Unseelie faeries.There is a poem for both Vivian and Evie. She is a bit evil and cannot control herself around paranormals.
