When you first heard of a conference of Witch-Hunters, your initial response was that it'd behoove you to be as far away from it as possible. But though it is hosted by the Cult of Sigmar, this is no hidebound coterie of fanatic Sigmarites, nor a collection of thief-takers and hired thugs given a dubious seal of approval by some regional authority. This is a gathering of representatives of every organization dedicated to the stamping out the Forbidden Lores of the Daemonic Powers, the unholy ways of Necromancy, and other sorceries and witchcrafts that utilize the wicked powers of Dark Magic. That said, those Wizards that don't plan on attending still make a point to keep inside the Colleges or outside of Altdorf for the duration, just to be on the safe side.
