From the back of the book: Cousins of the treants and guardians of the woodlands, the arborlings are a plant-like race of humanoids that stand outside the boundaries of civilization. They are deliberate and straightforward creatures who remain the constant enemy of those who seek to despoil the world or unduly tax the resources provided by nature’s bounty. While arborlings are an isolated race, remaining safe in their ancient homelands, a few have heard the call of the adventuring life. And now they stand poised to bring the power of nature to the bear against the evil forces in your campaign!
