Trope-a-Day: Knight Errant

Knight Errant: A relatively common profession among the young and frivolous (or the old and recapturing being frivolous – telling which is which is a useful survival skill if you’re on the other side), under a variety of job titles, including any and all of “adventurer”, “weirdseeker”, “freelance troubleshooter” and “mercenary”.

(Some of these, of course, are young, frivolous AI-controlled killing machines.  Watch out for those.)
