Citizens of Sanctuary! Let it be known that, when this day turns into night, the famed and mad wizard of Undermountain, Halaster Blackcloak, offers any of Sanctuary who would take it a path to the surface-the walk upward through the grim and terrying depths of Undermountain itself. Many will come to him, seeking to pillage the last depths of sanity and reason from his madness; many will ply through his tests, seeking the elusive dream that has held them at bay for so long; few, if any, will live to tell the tale of their journey out of darkness by ascending through the very heart of one of the darkest realms in Faerun.
For those brave or foolish enough to risk their very lives and souls upon the mad whims of Halaster Blackcloak, for those who would dare to break the chains of this Underdark by risking eternal enslavement, for those who will ask for Tymora to smile upon them as brightly as she ever has another, the path to certain death and doom-and through this gloom, the surface-lies through the abandoned crypt of Zovaldar the Malevolent. This night, if you dare to risk all on the whim of a crow's song, go to the tomb; and within it, an ending-be it your own, or one that leads to a story anew-shall begin.
