The Forgotten Realms [Fan Version]

The Underdark, a sprawling subterranean realm beneath Faerûn, is a labyrinth of perpetual darkness. Its tiered depths, Upperdark, Darklands, and Lowerdark, each possess distinct ecological niches. Civilizations, often malevolent, thrive in this lightless expanse. Drow, duergar, and mind flayers establish their domains, while aberrations like aboleths lurk in hidden waters. A complex network of tunnels and vast caverns connects these regions, fostering a perilous ecosystem. The Underdark's environment is defined by its lack of sunlight, unique flora and fauna, and the constant threat of territorial conflict between its diverse inhabitants. The Underdark is inhabited by many races, including aboleths, beholders, cloakers, derro, drow, duergar, dwarves, illithids, kuo-toa, quaggoths, rock gnomes, svirfneblin.
