Where the rule of law is seen as being absent, weak, or too oppressive to want, and crime of all kinds flourishes, sooner or later people will take the law into their own hands and become vigilantes. Here are seven such gangs.
I had me a dream once. Just after I *acquired* this here knife. Only the knife was a bit shinier and I was in an alley somewhere. I dunno, maybe it was Brie or Holsten, someplace like that.

The PCs encounter a strange set of artistic drawings done on the ground as they pass through a city. It has been done in chalks and no one saw who did it. Wizards might recognize the writing within the colored square as an obscure and dead language with a message stating that a prominent wizard and a retired bard have discovered how to populate Arcadia with the spirits of the dead!
Is it a local hoax, or are the PCs crossing the path of a very deranged and possibly dangerous mage?
