Um, don't call anybody else by their birth name because that entangles you to fairies forever, I am already entangled with that guy because we messed up, that guy is that person's owner and he's a fairy, that's the slave person and we're calling her Cecilia, if you ask questions of the fairy you end up in his debt and that, like, does magical entanglement things that mean if you do anything that fairyland disapproves of, mostly lying or breaking agreements or attacking people you're indebted to, you hurt everyone else who's entangled with the people you're entangled with, and which sometimes makes you end up enslaved I guess, and for that reason we are mostly asking questions of Cecelia.
