what would a Muse of Mind be like?

Commanding Choice, through Choice, Inspiring Mind, Commanded by Mind… Hmmm… Do you know how John started choosing a third, nonexistent Option at some point in the story? With Vriska, with Typheus teaching him to use his powers, I could somewhat see them inspiring this sort of thing, a choice on others that allows them to escape vicious cycles and loops, a way out. I could also imagine them talking to others through Telepathy.
