Shota (the Witch Women) to The Mother Confessor in a conversation about skinning a Wizard alive.

shota - " Do you know what he said to me, this wizard?"  "He said he forgave me.  Can you believe it? He granted me forgiveness.  And then he begged mine"

 
Mother Confessor - "Seems a strange thing for him to say, considering."  
shota - " The Wizard's Fourth Rule, he called it.  He said that there was magic in forgiveness, in the Forth Rule.  Magic to heal.  In forgiveness you grant, and more so in the forgiveness you receive."
