Every year, the Springflower Caravan arrives at towns and villages in this part of the country. It’s staffed entirely by goblins who sell only minor magic artifacts.
As might be expected, people are suspicious of the goblins and the provenance of the caravan’s goods, but on the other hand, you can’t find artifacts like these just anywhere. Inevitably, at least a few locals end up buying an enchanted broom or anti-poison amulet.
During their stay at a settlement, half the goblins scatter into the wilderness nearby. If asked, they claim they’re just foraging for herbs and mushrooms. The locals are even more suspicious of this assertion.
As a friendly faction, the Springflower Caravan legitimately trades in minor magic artifacts, its members often looting minor dungeons to acquire them. The goblins are friendly and will happily sell a variety of useful minor magical items to the PCs. The goblins will even take requests and look out for them in their travels.
As a foe faction, the goblins of the Springflower Caravan are actually in the employ of an evil wizard. They scatter into the wilderness to hunt magical animals, which they slaughter, harvest, and bring back to the wizard, who provides them with the minor magical artifacts they sell as cover. Worse, they target creatures that protect the wilderness, like dryads and even unicorns; killing those animals is very bad news for the locals.
