So...I've been regularly checking MMO-Champion's home page for the past couple days, and I have yet to see any news on the Book of Xereth quest line that leads us to green fire. If anyone has any updates please post here. Because I think I am not the only warlock asking this question...To those who do not care for green fire, all I can say is "Oh well." I'm just looking for updates on the subject.
