When Kushana was a child, she was handed a glass of wine. Her mother drank it instead and was poisoned with "a fearful poison that drives the spirit mad."
As a result, she is irrevocably insane. Kushana visits her before leaving for the Periphery Campaign. She protects a doll that she names Kushana from her real daughter. Kushana leaves her, promising to "smash the fangs of those who have tormented you and your daughter, my lady."
