Feydark

The Feydark was the echo of Toril's Underdark in the Feywild.

Description
like most parts of the Feywild, the Feydark was more majestic and fantastic than its natural counterpart. . Inhabited by the fomorians, a fey echo of the titans, the Feydark was a cavernous world of maze-like tunnels and portals linking to Toril and other planes.

Geography
The geography of the Feydark was similar to that of the Underdark. A maze of tunnels linking caverns permeated the Feydark. However, unlike the Underdark, the Feydark was home to terrain commonly found on the surface, such as forests and swamps.

Flora & Fauna
Unlike the Underdark, the Feydark was teeming with life. Despite the lack of sunlight, the Feydark's flora and fauna were as colorful and vibrant as their surface cousins. Many Feydark species exhibited bioluminescent characteristics.

Plants and fungi were pervasive and ubiquitous. A typical tunnel in the Feydark had its wall covered in vines and its surface covered in thorns and noxious flowers. It was common for the vegetation to be so thick it blocked a tunnel completely. A frequent sight was thick shrubbery growing on the roofs of caverns, appearing as upside-down forests. Damaged plant-life rejuvenated quickly, even a few hours if the location was ideal. The Feydark was also home to a wide variety of fauna. Large and healthy populations of amphibians, insects, reptiles and rodents fed on the plentiful fauna, which were in turn eaten by wild hogs and large flightless birds.

Inhabitants
Several sentient species make their home in the Feydark.

The most numerous and powerful were the fomorians. Fomorian kingdoms rivaled the size of surface realms, filling massive caverns and stretching out along endless tunnels. Cyclopses, servants of the fomorians, also made their home in the Feydark. When a cyclops was encountered in the Feydark, more often than not they were on a task given to them by a fomorian master. They served the fomorians as soldiers and guards, as well as smiths. Cyclops forges created powerful, and devastating, magical weapons.
