This is a tower of the Void, similar to The Obelisk of Lost Souls. Inside, a shadowman ruler named Axxyk'Tuur has been tasked with infiltrating fae society in order to absorb them into the Void army, or if they should prove too resistant, simply burn their souls for energy. Through investigation it is revealed that Axxyk'Tuur and the Obelisk of Blight have another directive, once that involves the protection of a device capable of controlling a powerful Norrathian dragon.
Notes[]
There is only one re-pop in the whole zone, an advanced automaton, circling the ceiling in the center chamber of the final encounter area. This is certainly the guardian mentioned in Tower of Zet Scroll No. 3.
