In stark contrast, Xena is cynical, hard, and world-weary. Xena has killed thousands of people and, overcome with guilt, is returning home, perhaps to give up her own life. But on seeing Gabrielle's willingness to sacrifice herself for others, she is inspired to spend the rest of her life redeeming herself, and this becomes the driving theme throughout the show. Together they embark on an arduous, spirited adventure lasting over 30 years. Gabrielle acts as Xena's guiding light, keeping her dark memories at bay and reminding her of the goodness that she had once possessed. In return, Xena provides Gabrielle with travel and great adventures, teaches her about survival and the fighting arts, and acts as her protector, both physically and spiritually.
