The Feylines occupy the northeastern Riverine Heartlands, a domain defined by the Atrix Web mana conduits. Vast plains and gentle hills support a tapestry of fey civilizations, from grand elven spires to nomadic centaur camps. High magic permeates the soil, fueling rapid growth and arcane weather. While various races maintain their own hubs, the land remains a collective effort of shared defense and magical industry focused around the living mana lines that bind them.
