Sweat of Danzar-Khâl

What happened after the Black Tide was defeated and sent fleeing back to Necrocrypt? 

Katrana and friends

That story is still unfolding, but here is a nugget of holy crusaders storming the palace of the Lich Empress - does she perish?  Well sort of, but a super bad ass does not take a dirt nap so easily, for in the end, all are just pawns of even greater powers.

One of the things that helped bring her down for a time is a magical pool called the Sweat of Danzar-Khâl.  This pool of holy water is sited in the area of the Monument of Šadullu.  The Last Saints of Gûn, former high dwarven priests of Maharâg, and the soldiers accompanying them coated their weapons with this stuff and then reapplied it many times, striking Katrana Dumu-loc 99 times.  The number of hits against her is testament of an extremely powerful foe.

The Sweat of Danzar-Khâl acted as a holy curse on Katrana, causing her evil essence to wander lost for almost a century.  The final outcome of what happened to her when she finally found her phylactery is covered in the Monument of Šadullu.
