Many of the Feywild monsters of the surface wander among these mutant forests, along with creatures even more bizarre. Giant insects swarm through the ooze of fungus and silt, often exhibiting great intelligence. Gnomes send regular expeditions into the Feydark, searching for magical stones used in their research. Drow on missions from the mortal realm use these tunnels to travel without alerting the eladrin. Strange humanoids that can only be described as “mushroom folk” gibber and puff spores as they scurry in the shadows. However, the undisputed masters of the Feydark are, of course, the fomorians.
Translucent, glowing purple crystals light the Feydark in an unearthly glow. Where the Underdark is bare stone, the Feydark is lined with bizarre fungi. Forests of mushrooms, as tall as a human, cling to the jagged cliffs descending deep into the earth. Waterfalls run blood red with algae that’s evolved to live off the magical emanations. Poisonous blue moss lines the tunnel walls, and shock stones lodged in the onyx walls absorb travelers’ torchlight and convert it into sparking electrical energy.
