Drezen

Founded as a city-fortress during the hubris of the First Mendevian Crusade, Drezen was overtaken by the demonic hordes of the Worldwound. It now stands as a demonic monument to the foolish naivety of those early crusaders.

Drezen was overwhelmed in 4638 AR; a wave of raw chaos washed over the city turning most of its citizens into hideous beast-men creatures who turned on each other in a wave of cannibalistic fury. After the slaughter finally stopped, the corpses were taken from the city to the ice cliffs that mark the Crown of the World. From these corpses arose the foul winter wraiths who are capable of freezing a man dead with but a touch.

Saint Argil, also known as the Pauper Sorcerer, was martyred as he defended the fleeing people against the demonic armies.

The city's once proud crusader shrines dedicated to Iomedae, Sarenrae and the other crusader deities are now perverse mockeries dedicated to foul demon lords. The city is now home to thousands of demons, led by one of the most ruthless demonic generals of the Worldwound, the bloodthirsty marilith commander Zuhra Aponavicius.
