I believe one of my good friends may have an idea for an additional source of power for Ketharas's gambit. He is close friend, of course, and he will be thrilled to lend his aid to an agent of my will such as yourself! You can find that old stinkfeather in the area south of here that is crawling with undead. Mourning's Rest I think you mortals call it? Make sure you mention that I sent you! He will LOVE that... most certainly!
