I personally think that we should go with a sort of tone that befits our image. Something quietly powerful, words calm, direct, and invigorating. We do not need to scream and throw around power to make them pleased; auras are something that people can't really see, but I think that they can feel it...and our aura should be one of power, composure, and utter calmness. We look down on possible enemies with an apathetic, cold stare that would make them bow before us, so that we don't even have to waste time, while we treat our allies and servants to a calm leader that won't flinch, our words filling them with moral and calming any doubts. That's my thoughts on the matter.
