Abyssia

The Underdark? Why would we want to go there? There's nothing but death and monsters down there.- Some poor Adventurer

Abyssia other wise known as the underdark is a collection of tunnels and caverns interconnected in a vast underground realm. Manner dark monsters and denizens make Abyssia their home.

Geography

Large and small caverns connected by a vast network of tunnels. Its easy to get lost down there.

Ecosystem

Harsh and unforgiving. Only the strong survive here.

Climate

Cold and damp. Whats that slithering at your feet? Whats dripping on your head and down your back?

Fauna & Flora

Much of the flora and fauna are definitely out to kill you, its not an illusion. Steer clear of strange fungi and acid pools filled with Death Piranhas.

Natural Resources

Rich veins of rare metals, Gems and other useful ores. 
Certain Kinds of Mushroom

Tourism

I wouldnt call adventurers and travelling merchants very touristy. If you do feel like venturing down to Abyssia, be sure to take lots of provisions and protections. Wouldnt want you to die of thirst or hungry, or Gods forbid, eaten by a Bullette.
