Bloody Disgusting learned exclusively that Dark Castle Films is developing a new horror film entitled Library of Dust. While details are slim, we did manage to get our hands on the following plot: "The ashes of the unclaimed dead at a psychiatric hospital undergo chemical reactions causing blooms of color corrosion, revealing unexpected beauty in the most unlikely places." Dark Castle's been picking up steam with their releases and have a ton on their plate including The Factory and Unknown White Male.
