Smallfolk is the common name for for different sentient spieces, all shorter than the average human. They are, from tallest to shortest: Halflings, Hobbits, Goblins and Gnomes.
What they all have in common is that they were all created by gods inspired by the already existing humans and by each other.
All of the above is subject to change as I get used to the idea. This post is of the “type first think later” variety.
