I've accomplished my duty as a soldier, now is the time to get some answers.$B$BThis lich has knowledge I seek, yet I cannot inflict pain to his physical body to obtain that knowledge.$B$BThe lich stored his soul in a phylactery, and while it remains hidden, I won't be able to pry the information from him.$B$BReturn to the camp and take my horse, Dusk, she will lead you to the phylactery. Bring it to me.
