An archfey that made a pact with Selene McCoy at some point, also known as The Swamp Sage. Nuferos, residing in the Archive of the Black Bog, in his own Domain of Delight called the Swamps of Telmais, is obsessed with knowledge and secrets of all kinds, and always eager to acquire them by any means necessary; this includes kidnapping those who know secret or hidden knowledge. While not a proper member of the Seelie Court or Unseelie Court, his mannerisms, aesthetics and general values fit more with the Unseelie Court, to the point of even sometimes dealing with members from it; when he isn't hiding in his swampy archive, that is.
