Archetypes are something of a quick little cheat-sheet to help shape a character, and also define how a character regains Will.
Bond: This is what ties your character to the world of the living. A character’s bond is there hook into motivation for interacting with the story.
Virtue: This is a moral concept a character holds above all others. It is often a slogan or an easily remembered rule that the character is disinclined to disobey.
Vice: This is a shortcoming your character has that either impedes their progress in pursuing what they want, or is a stumbling block on their path to their virtue.
Demeanor: This describes a personality that the character likes to affect or maintains.
