A Toreador (with Auspex, Celerity, and Presence) singer who was kidnapped by Setites and blood-bound to work in their London Brothel. The nature of her work there is not expounded on beyond Lily's statements about the Vampiric Kiss of blood drinking ("most mortals love the delirium that comes from being a blood donor to a vampire. especially the way I do it"). Like Serena before her, she seeks to alleve Christof's pain at his separation from Anezka.
Christof and Pink rescue her (and eventually her Sire), making for an additional team member. She is not that powerful at first, starting off as barely a Neonate, but she has a lot of branches where she can develop, and all of the Tomes available in the Modern Times (Lure of Flames, Potence, Protean, Mortis and Animalism) to choose from. Dominate cannot be used because the tome comes from the Factory in New York and she gets it automatically after killing Lucretia in London. Obfuscate from the Setite Temple is not recommended because she gets it automatically after Alexandro Giovanni is killed.
As such, Lily is invaluable in the Nosferatu's Sewers. She is also the only character in the game who can always see Obfuscated characters and also be able to cast Awe on them, since neither Presence nor Auspex tomes are available in the single-player game.
