In an effort to maintain a mortal guise, the vampire Arjun and his maker-companion, Pandora, take the name de Malvrier but add the noble titles of Marquis and Marquisa, to associate among the ranks of nobility in Dresden, particularly in the palace. The rank of marquis is lower than prince yet higher than count.
The “Marquis de Malvrier” alias appears in Blood and Gold (2001). For more perspectives on this alias, read the Alphabettery entries Arjun, Marquisa de Malvrier, and Pandora.
