How many of the people who knew Tom’s true name are still alive? It started at about 20 and rose to maybe 26 tops, but I can only confirm about less than half of those people as still being alive.
Also what would happen if a demon where to learn a human’s true name, and is their a way to force a human to relinquish their true name in Astlan.
You know apart from forcible removing them from their body, severing from their silver cord, and then placing them inside a circle that compels them to name themselves.
