Legend has it that an ancient great demon met its end here, turning this region into a forbidden zone for all living things. In every generation, daring or duty-bound cultivators have ventured deep inside to explore. Strange phenomena abound: eerie, dense fog that devours spiritual energy, and mournful horn calls that rob people of their reason, sounding day and night without pause. There is also an invisible barrier that seals the place from within. Getting in is easy, but fewer than one in a hundred ever makes it out. Yet immense dangers come with immense temptations. The abyss breeds mutated spirit beasts and bizarre medicinal herbs never seen in the outside world. And legend has it that the fallen great demon's fragments of divine spirit are the ultimate treasure, drawing top cultivators to venture in one after another.
