Antagonists is a sourcebook on antagonists for The Masquerade, the Mind's Eye Theatre live-action roleplaying game that later became Laws of the Night. The book covers a number of mortal and supernatural antagonists for vampires, with a focus on hunters and the Sabbat, and provides full MET rules for creating characters from these diverse backgrounds. A number of details are drawn directly (albeit in a very condensed format) from The Hunters Hunted, Mummy, the Players Guide to the Sabbat, and the Year of the Hunter sourcebooks The Inquisition and Project Twilight.
