The Realm's Edge is the term for the distant frontiers of each of the Mortal Realms, where solid geography gives way to raw, untamed magic. Because a realm's ruling wind grows stronger the farther one travels from its inhabited heartlands, the edges are regions of impossible, ever-shifting terrain, where the defining force of the realm reaches an overwhelming, world-warping intensity.
At the edge of Aqshy the very air becomes fire; at the edge of Ghur the land itself hunts; at the edge of Chamon reality transmutes with every step. These are places where the laws that govern the realm's centre no longer hold, and where the substance of the world dissolves back into the elemental sorcery from which it first condensed. Few travellers who venture that far ever return, and fewer still return sane.
Despite the danger, the Realm's Edge draws the desperate and the ambitious. Its unfiltered magic is a source of raw power and rare materials found nowhere else, and legends tell of hidden wonders, lost civilisations, and gateways to stranger places still beyond the final marches. To reach the edge is to stand at the border between creation and pure sorcery, a threshold that has claimed countless explorers and rewarded a bold, fortunate few. It is the ultimate wilderness of the age, the place where the map of the world simply ends.
