Byd Dwyfn

"Dark, univiting, dangerous - just three of the words that can be used to describe the subterranean depths of Byd Dwyfn. Its myriad depths and labyrinthine passages are not to be travelled lightly.  I, personally, have only ventured down there once and it is not an experience I care to repeat for there are more dangerous things than the drow and the duergar dwelling in the deep places of the world."

Amarin of Malfabar

Byd Dwyfn is the name given to the vast subterranean region below the surface of Arcania.
