Laws of the Night

Laws of the Night is the core rulebook for the Mind's Eye Theatre adaptation of Vampire: The Masquerade. The MET Vampire rules were originally titled The Masquerade and published in the same larger format as the tabletop roleplaying game that inspired it; LOTN and nearly all future MET books instead used a smaller format that would be more easily portable for live-action play.
