No Mortal venue game is required to be focused toward the extermination of supernatural creatures (as might have been implied by the title "Laws of the Hunt"). For the purpose of Mortal venue games, the Storyteller must also supply a Setting. This can sometimes be defined in as little as a single phrase or sentence, such as 'FBI Special Affairs Department' or 'A Cabal of shamans dedicated to worshiping Rat, and defending her people'. Obviously these two Settings have little or nothing in common, meaning that cross-Setting play would be as difficult as or more difficult than cross-venue play. If the excuse for a character to show up in another Setting of the Mortals venue is too improbable, the Storyteller is encouraged to deny it.
Storytellers must be very careful with games in the Mortal venue, lest they turn into 'zoos' supporting many different characters types who have nothing in common. Venue Style Sheets are extremely important for letting players know what sort of Mortal game is being run. Storytellers will deny vague Settings in a Mortal game’s Venue Style Sheet. Play of a mortal character in a Setting that is not appropriate to it is considered to be “cross venue” play, and is handled according to the rules in the Prime supplement.
