Arthfael "Lucifer" Mendax, also known as Optimates Lucifer, or Optimates Arthfael is one of the four lords of Hell. He's also known by many other titles, including, but hardly limited to his favorite title "Prince of Lies" and like the other Optimates he possesses near god-like power, although he's very uninclined to make use of it, preferring much rather to arrange balls, banquets and high-class parties.
