Trolls are one of the five main Races depicted in Terry Brooks' Shannara series. Like the Dwarves, the Gnomes, and the Race of Man, Trolls are descended from humans who survived the Great Wars. Their natural home is the Northland, which is characterized by harsh, rugged terrain. (There are several types of Trolls, but Rock Trolls are the only one described in any substantive detail in the Shannara series, and "Troll" is often used as a general shorthand for Rock Troll.)
