Use Pathfinder missions as a front for personal gain.
A loose affiliation of Varisian swindlers, thieves, and smugglers, the Sczarni don't have much in common with the average Pathfinder. But to many, there's little distinction between someone who robs the grave of an ancestor and someone who cons one out of her night's dinner. Thus, when Sczarni and Pathfinders come to town, both are often lumped into the same category by suspicious natives and watchful legal authorities—troublesome people to watch out for. Though not officially allied, many Pathfinders work with local Sczarni throughout the region to aid one another in surviving, hopefully gaining a leg up in their own endeavors in the process.
Guaril Karela is the mastermind behind all Sczarni activity in and around Absalom, and as so much of the region's business takes place at least in part in the City at the Center of the World, Guaril likes to think of himself as more important on a global scale than perhaps he truly is. Despite his delusions of grandeur, he maintains a low profile working the counter at the Pickled Imp, his curio shop in the Docks. From this strategic location, the ever-smirking charlatan keeps a close eye on what lucrative shipments come into the harbor and what warehouses are left unguarded. The constant flow of dingy sailors and visitors from all over Golarion means that Guaril's agents, both Sczarni and Pathfinder alike, blend in perfectly as they stop into his shop for a tip or to pay respect for a past job.
The Sczarni Pathfinder
Some Sczarni find a life of wandering leads them eventually to the Grand Lodge to become part of a larger organization, though these Pathfinders never lose their loyalty to their Varisian roots. Similarly, Pathfinders of any ethnicity looking to swindle, smuggle, and steal at every opportunity find that they work well with the Sczarni operating throughout much of the world. Ever opportunists, Sczarni know when the Pathfinder Society provides a great cover for their unscrupulous ventures, while similarly shrewd Pathfinders see the benefit of having contacts in nearly every port, especially ones skilled at getting valuable cargos past prying harbor watchmen and tax collectors. Most Sczarni Pathfinders are chaotic-aligned.
