Below the Root is an aventure game released by Telarium (later known as Windham Classics) in 1984. It is based on the Green-sky trilogy, published between 1975 and 1979 by Zilpha Keatley Snyder. Though not a typical example of an adventure game, Below the Root featured the largest game world of any adventure game available at that time. 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.
