Lucien Vanserra

The seventh and youngest son of the High Lord of the Autumn Court, Lucien is the black sheep of the Vanserra family. He left his family to serve Tamlin as an emissary for the Spring Court. He wears a fox mask when Feyre meets him, as he has been cursed along with the Spring Court and is unable to remove the mask. 

Lucien has red hair and is often compared to a fox. His complexion is noticeably darker than all of his brothers. His face was brutally scared after an attack by Amarantha when she carved out his left eye. A friend from the Dawn Court crafted him a golden metal eye as a replacement. 

Lucien first appears in A Court of Thorns and Roses.
