Though the humans may defy me on the other fronts, it is important to our plans that you succeed in your assignment. To you I give the task of destroying humanity's memories of their triumph against the Hopeslayer. Once you enter the shade realm of the Quiddity Seed, you must steal the skull of Avoren Palacost. The skull, which belonged to the Hopeslayer's male offspring, was a critical part of the ritual that Asheron used to weaken Bael'Zharon.
