The Feywild is a parallel plane to the Material Plane. Unlike the Material Plane, the Feywild is fueled by wild, magical energy drawn from the emotions of its inhabitants. Because of its connection to the Material Plane, the Feywild has similar topography and geography to the mortal world, though exact locations are constantly shifting and are therefore impossible to plot. Although the general geography of the Feywild and the Material Plane is similar, the Feywild has a much more primal landscape.
Nature rules in the lands of fey. Where you would find sprawling cities in the Material Plane, you might discover only hunting outposts or desolate ruins in the Plane of Faeries. Similarly, locations with patches of wilderness in the mortal realm could be vast, impassable forests in the Feywild. This raw, primal magic makes the Feywild an extremely dangerous place, even for those who call it home. Adventurers, or those unlucky enough to unwittingly stumble into this land from the Material Plane, must ensure they are not lulled into a sense of complacency by the Feywild’s beauty. The sporadic, magical nature of this land can kill mortals as quickly as any of its dangerous inhabitants.
