Polywiki are some kind of distant relatives to the dwarves, but not quite dwarves yet. They are stout, males have beards and they are NOT friendly, at least not to people.
They seem to be tied to the earth, but additionally to plant life, as they grow green plant like hair. They have nut brown skin and they are hard workers. They work in the gardens, they work in the groves, they work in the fields, and they are master botanist and are such hard workers that they are known to punish laziness by death. Wow…what if these guys were my parents? They must not have many children who make it through their teenage years. I don’t know if they are “evil” but I know they are not good either. I would place them at Chaotic Neutral.
I’m sure they have an array of magical powers having to do with plants and nature, just like Dryads and Hamadryads and Treants.
