From the description:
The Nameless Exhibition (just “the Exhibition”, to those in the know) is an old tradition borne from Doskvol’s strong academic heritage and the whims of its nobles. It’s a secretive annual party where the city’s elite gather to be occult tourists, slumming it with the dangerous and arcane in a safe environment.
The Exhibition began in Nightmarket, but in the last few decades it’s moved to Ebongarde Manor in Six Towers. The Ebongarde family has since fallen and the manor is crumbling, but thanks to the Exhibition’s noble sponsors, it always has clean floors, a full pantry, and a powered laboratory on the day...
The Nameless Exhibition is a score/scenario for Blades in the Dark, with a few extra pages of NPCs for the GM to use.
