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. 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.
