Pro by Night (also called Proelium by Night or PbN) was a story at Proelium (since renamed to Profusion). The story involved a cadre of vampires (including Pasht) holed up together in a castle, existing non-lethally and putting up with humans attacking their home. The usual vampire clichés got subverted, inverted, or otherwise generally tweaked.
