While obvious things such as murder and theft are illegal in Ptolus, so are compulsion spells cast upon citizens (locals frown on charming shopkeepers to get a better price) and spells of mass destruction cast within the city proper (no fireballs or disintegrate). Any spell with the evil descriptor is also illegal; in particular the authorities hate animate dead and other spells that bring more undead to the city. They also prosecute people severely for doing anything that spreads disease—including casting contagion. These and other crimes can be reported at the district’s Watchhouse.
