This thread is over 3 years old, but I still felt compelled to add my two coppers. :wink:
THREAD RESURRECTION, BABY!
I see Temptresses as any type of female character that can manuipulate other people behind the scenes. Sometimes they use their sex. Sometimes they use their natural charisma. Lady MacBeth is a Temptress. Lady Regan Hamleigh in the recent Pillars of the Earth miniseries is a Temptress, tempting her son as she would bid. Olympias, in the film Alexander, was a Temptress.
I can also see men playing the role. Anytime there is a Machiavellian-type character, he would be a Tempter class. Grima Wormtongue, in The Two Towers seems to be a Scholar/Tempter multi-class.
An example of another male Tempter may be a priest. But, a priest may be a Scholar or a Tempter (or a multiclass of the two), using the power of faith his believers have put in him to manipulate them into doing his bidding. The cult leader with fanatical followers is a Temptor class.
