A reminder from the Watch, the Council decree authorizes the city's Defense Leagues to enforce its policy. Not citizens, citizens murdering "monstrous races" within Sanctuary and violating their ban will face charges for their crimes.
Council Decree on "monstrous" Races
Citizens!
Be warned, you are not allowed to slay Illithid or Beholders that come into the city. So says the Watch.
[Any stupid additions to the Notice made without watch permission are taken down, folded up, shredded, burnt, and then thrown in a trash container by a slightly pissed off looking female watch sergeant]
