The Eastern Spine is a range of hills which stretch from Mt Serenity in Falahn to Spring Hill in Nashun. They divide the watershed of the Bay of Apaturi from that of the Eastern Sea. Most of the spine is situated in East Mearor. The rivers Elee, Yare and Thorby all have their source in the Eastern Spine. The northern end has a few skiing resorts, while the southern end is mostly used for sheep farming, as well as some mining of the limestone of which the hills are made.
