"Below the Root is an adventure game released in 1984 by Windham Classics, a division of Spinnaker Software. It is based on the Green Sky trilogy, published between 1975 and 1979 by Zilpha Keatley Snyder. The player can assume the role of one of five characters with different abilities, a member of one of two races — the Kindar or the Erdling — and attempt to settle the existing differences between the two groups."
