Overview:
The Underdark is a vast network of caverns and tunnels that runs beneath the entirety of the Feywilds. Although attempts have been made to enter it, and map out its enormity, most expeditions fail fairly quickly owing to the numerous monstrosities that roam its depths. Strangely, almost no creatures from the Underdark seem to have made their way to the surface, although whether this is by choice or not is currently unclear. What is clear, however, is that the Fomorians are the only known species to regularly travel in and out of the Underdark.
