Trivia

 * Taliesin's described his inspiration for Mason's character on the Critical Role blog as follows: "Every job needs an inside man, and Dr. Pocket was our access to the main artifact — as well as the excuse to set up the rest of my occult mouse traps. I gave Phil just enough solid information to guide the group through this new mythology while making sure he would be tempted to fiddle with at least one of the triggers I had spread around. Phil eventually ran with the tiny bit of information I gave him and managed to put forward several impressive theories on the shadows that were SCARY close to my secret canon."
