The Powers That Be tolerate a scummy class of itinerant murder-hobos that often kill monsters for pay (Or, even better for the taxpayers, just for the monster's treasure). Conveniently, many of these ruffians are religious fanatics of some type or another, or at least consort with them. Conveniently, magical weapons often have a way of making it in to their hands. They keep the monster population in check, and society long ago decided that was worth the occasional raped barmaid, clumsy coup attempt, or eldritch horror accidentally unleashed from an ancient subterranean prison.
The Seven Swords of Sarnath and their "Pet" hook horror have just pulled up in town in their armored coach and accepted an offer to kill wights for 100 SP a head. Infamous alcoholics led by a Paladin of a dead god and with two named magic swords, three wands, and an AK-47 with half a clip (Don't ask) between them, they don't play well with others, especially other "Crawlers". Lock up the booze and send your daughters out of town. Things could get ugly fast.
