My sphere is Guardian (Person of great Love and Altruism), and my class is Rogue (Precise and Unhindered).
I am a Protector.
You won't let anything or anyone threaten the ones you love if you have anything to say about it -- and you aren't afraid to back that up by any means possible. You might get your hands dirty in your life. You might do things that more lawful people would question. But there is no doubt in your mind that what you are doing is right, and you will have no regrets. To be a Protector is to shed many layers of "status quo," of "morality," and, to a degree, of honor, in order to dedicate yourself to the protection of your love in any way you can. You are a truly rare breed. You are loved in return for your great dedication by the people who value you. You know how to keep secrets, and uphold your word.
Not sure how well it matches, but certainly a lot better than the other alternative they suggested:
My sphere is Soldier (Unity in Strength and Action), and my class is Rogue (Precise and Unhindered).
I am a Dark Artist.
If you were in the Republican Convention during Nixon's term of office, you would have been the one they sent to spy on and infiltrate Democratic Headquarters at Watergate. This isn't to say that you're a man of black operations or ill repute, but more to say that you have the efficiency and swift approach to carry out these tenuous, sometimes questionable, goals when most of your comrades might balk.
