Wanted: Zar'nai

A powerful lich has seized its hold over the trolls of Zul'Mashar. The lich itself has been deemed far too dangerous even for your abilities, but it has used the corpse of a long-dead warrior called Zar'nai as a weapon to attack our forces in the area. We would like you to destroy Zar'nai at Zul'Mashar. Be warned, our attacks have proven entirely ineffective against Zar'nai. You may need to find a way to break the lich's protections before you can slay Zar'nai.
