A Folk is a character species on Earth that is somehow immune to the Corruption. They have set up settlements all over the world. Your game character and most of the other characters you interact with are Folk.
Before the Corruption began, Folk conducted trade with many of the monster species. However, since all the other species have become corrupted, the Folk have dedicated their time to helping cure the monsters.
The Ministry of Monsters was formed to have a central intelligence organization to keep track of any areas where corrupted monsters seemed to be out of hand. Made up almost entirely of Folk, the Ministry helps train young Folk to be master trappers, chefs, and farmers to help keep up with the modern demands. They hope to be able to harness Gnomish technology to find the source of the Corruption and put a stop to it.
