Never Rest On Friday- The 1 and Only

Those who are supernatural must live among humans or die if they commit a crime. A vampire cannot feed on or turn something without consent. Werewolves cannot attack humans unless it is self-defense and they cannot turn someone unless they are given consent. Witches are not allowed to cast harmful spells against anyone for profit or malice. According to those who maintain the world was better with just humans, a supernatural being will step out of line every Friday, and that's become a fact over the past two centuries.
