Investigator
You might be a criminologist on the city payroll, a public prosecutor, part of a military tribunal, or a private amateur whom the local authorities rely on to help solve crimes. Consider what case might have most affected you, and whether you are still in contact with any of the victims or perpetrators.
A uniform and/or a badge, a set of manacles lined with a gold wire (to prevent teleportation), a magnifying glass.
In any community you visit, you can easily locate local outposts of city watch or similar organizations, as well as dens of criminal activity. As long as you don’t abuse the privilege, you can call upon someone (such as a Police Officer, see page 231) to help you on official business, providing enough authority to get most suspects to agree to be questioned (and maybe come in “for a few follow-up questions” when you intend to reveal that you’ve solved the case). This ally will defend themselves if attacked, but isn’t loyal enough to go along if they know a fight is imminent.
After you solve a case or two,your exploits may make it to the papers, and would-be masterminds might taunt you with crimes intended to thwart your powers of deduction.
