Herein is the collected wisdom of Dr. Jenna K. Moran, the RPG designer formerly known as Rebecca Sean Borgstrom. Aside from writing Nobilis, she wrote the original and still best 1e Sidereal Charmset, the 1e Fair Folk Charms, and the 2e Solar Charms. You thought she was speaking figuratively, and this is why you weep.
