All in the title give us your ideas for servants with an extra class, those classes outside the standard seven. Can be a new servant or a preexisting one given a new class, serious or silly. Give the servants name, their class, and a brief description. For extra credit add NP, skills and any other details you'd like.
Example: Satan (Caren), Beast VI/A: Once an angel of god whom served as the tester of faith, the demon who opposed divinity and represent the sin of wrath. Unlike other Beasts Satan has not come to end humanity, but to test them to act in their angelic role as an Adversary to be defeated. This is likely why Caren Hortensia was willing to allow this being to use her body, an act she seems to consider as holy rather than blasphemous.
NP: Gehenna Aeterna: Divine Flames of Judgment: A hellish realm of divine judgment where the damned are said to wallow in eternal punishment. This Noble Phantasm is a manifestation of that realm, a manifestation of Hell which scorches the earth and denies to concept of Death forcing all caught within to writhe for all eternity. In its current state it is merely a Reality Marble that temporarily confines enemies within however if allowed to grow in strength it will become a Marble Phantasm that covers the entire earth. But the Master of Chaldea will overcome such a trial, right?
