The Spine is a mountain range that runs down the west coast Alagaësia. It has only one major pass, along the Toark River; the lack of any other serves to isolate the coast. Most people in the Empire fear the Spine and the danger it represents, partly because the King lost nearly half his army in it during his campaign against the Dragon Riders. Urgals and other monsters are believed to live in the Spine. The Spine is hazardous to humans.
