Underdark

The Underdark isn't one specific place, but in fact a vast underground inhabited by drow, duerger, dwarves, deep gnomes, spiders, and tons of other creatures. It is very dangerous, and is to be traveled through with caution.

Location: Under the Old Barn, and basically any area that is underground (except Neversummer Underground) like the Menzoduran tunnels and can be reached by many areas.

Inhabitants: Driders, Hook Horrors, Drow Scouts, and many others I can't remember. Anyone else feel free to add on <:D.
