Through dreams, visions, and omens revealed in sleep or the reverie, the Daughter of the Night Sky unveils the next step along the path and the next destination on the endless journey of mystic wonder that is life and death and life.
My character would use shadowdancing abilities to coax audiences into a higher state of consciousness with liquid-smooth graceful movements (starting at a comfortable pace and slowing down as he draws in the audience's minds) and mystifying elusiveness. If he did this wandering the nonelven lands *cough*Cormyr*cough*, would this please Sehanine Moonbow sufficiently that she would consider him a good follower and give him a place in the afterlife? (Oh wait, do (half-) elves already have a guaranteed place in Arvandor?)
The main scruple is that she seems to only involve herself with (half-)elves, and there would not be many elf-kin to be audience. I guess he could just be a dancer who only happens to really please his goddess when elves are watching.
