This screen is the perfect companion for dungeon masters running the Out of the Abyss adventure, or any other trek in the Underdark. The front features ominous imagery of several demon lords while the back provides quick reference to maps, random encounter charts, and everything else you need for an extended stay in the Underdark.
The Underdark is an underground wonderland, a vast and twisted maze where fear reigns. It's the home of gruesome monsters that have never seen the light of day. It is here that the dark elf Gromph Baenre, Archmage of Menzoberranzan, casts a crude spell intended to ignite magical energy that conjures the Underdark and tears open portals to the demonic abyss. What passes through surprises even him, and from then on, the madness that permeates the Underdark intensifies and threatens to shake the Forgotten Realms to its foundations. Stop the madness before it consumes you!
